Epstein Barr Virus Analysis

Epstein Barr Virus Analysis
Epstein – Barr virus (EBV) is an enveloped, dsDNA virus, member of the Herpesviridae family and Gammaherpesvirinae subfamily and it is a
common pathogen, currently present in over 95% of the adult population (Murray, 2012). The virus is the primary cause of infectious mononucleosis
both in childhood and adulthood. The disease is caused by proliferation of infected B cells and later their destruction by activated T cells (CTLs). EBV
infects the mucosal epithelial cells, releasing progeny virus into the saliva and the B lymphocytes which leads to a long term, latent infection with little
or no production of progeny virus (Acheson, 2011). Chronic EBV infection has been linked to multiple diseases including Burkitt's lymphoma, Hodgkin
disease,

Although the aforementioned symptoms are suggestive of IM, a subset of infected patients may be asymptomatic (e.g., subclinical IM) or their
symptoms may be attributable to other illnesses such as acute HIV, cytomegalovirus or Lambert–Eaton myasthenic syndrome.1 In order to differentiate
IM from other illnesses, diagnostic tests such as the mono–spot assay or EBV–specific antibodies should be

Mononucleosis Research Paper
Mononucleosis
By age of 5, about 50 percent of children in the United States have already been infected by mononucleosis. This disease pops up frequently on
college campuses, where one out of every 200 students get it each year. Though it isn't very harmful it can last a while, and sometimes in rare cases if
not treated it can be fatal.
Mononucleosis is a virus caused by the epstein–barr virus. Which is also known as EBV. Mononucleosis (also known as mono) is most commonly
known as the kissing disease. It is a fairly well known disease and it's not a very harmful one, though it is highly contagious. It can be spread through
kissing, sharing drinks, or anything where you exchange bodily fluids. So it is easily spread within families.
In 1990, September 11th through October 7th there was an outbreak of mono in Puerto Rico. It started out as just a few people but at one point
about 70% of Puerto Rico had mono. It spreads quickly and easily so more and more people were getting infected. Though mono isn't very harmful
to people, it stops you from being able to do lots of activities and lasts for about two weeks or more. Doctors started investigating why it was
happening and they discovered how contagious it ... Show more content on Helpwriting.net ...
There was an outbreak where 450 students got mono. After that, they then began a 5 year study on it. The next time they started studying it again was
in 1971 when at yale university, over 16 people were diagnosed with mono. Then, in 1972 2,851 people were infected in college campuses in the united
states. In 1974 it infected a military academy in the united states where 53 people were infected. In 1979 there was an outbreak of infectious
mononucleosis that infected college campuses around california and hawaii. After that in 2013 there was another outbreak in college campuses and
there was another study on it and they found that 51 people in a high school had mono without even knowing

Infectious Mononucleosis is a viral infection characterized by swelling of the lymph glands. Mononucleosis is more commonly referred to as
"mono" or "kissing disease" because it is transferred by saliva. Mono was first named "glandular fever" in the 1880s by a group of german physicians;
the name stems from the characteristics of having swollen glands and high fever. Glandular fever was given the name Infectious Mononucleosis in 1920
by Thomas P. Sprunt and Frank A. Evans. In 1932, two researchers that go by the names of Paul and Bunnell discovered a way to help doctors
diagnose mono more accurately. A few years later Anthony Epstein, Barr and Achong discoveredEpstein–Barr Virus (EBV) in the year 1964 and
categorized it in the herpes family. Epstein–Barr Virus and Infectious Mononucleosis had no connection until 1968 when Gertrude and Werner Henle
discovered how to inoculate EBV and found a link between the two. ... Show more content on Helpwriting.net ...
About 85%–90% of Americans have developed antibodies to the Epstein–Barr virus by the time they are 40 years of age, which indicates that they have
been infected with the virus during their lifetime. A person can live with someone that has EBV and never become infected, but it is possible that a
person is susceptible to spreading the virus even if they no longer have symptoms. Epstein–Barr virus lives in the nose and throat and is spread when a
person comes in contact with infected saliva, tears and mucus.
The most common group of people to contract EBV are teenagers from the ages of 15–17 years old, but anyone can contract the virus. Young adults
that become infected with this virus will usually experience common symptoms, such as, headache, sore throat, fatigue, swollen lymph nodes, fever
and in some cases an enlarged spleen. Swelling of the spleen can get as large as two to three times the normal size and occurs in about 75 out of 100

Causes And Effects Of Cancer
Cancer is a name given to collection of various diseases that are caused by a similar mechanism: uncontrolled division of cells that results in formation
of abnormal cells that grow without stopping – tumors. Cancer is caused by changes in genes of the cells that control the way they function. Those
changes can be caused by various environmental factors, such as excess ultraviolet exposure from the sun, chemicals in tobacco smoke, radiation from
radioactive elements and many other factors. The only type of cancer that can be caused by an infection is the viral cancer. Viruses that cause cancer
are called oncoviruses; oncoviruses represent approximately 15% of all human cancers worldwide (Liao 115). Viruses are made up of small
portion of either DNA or RNA(sometimes both) surrounded by a protein coat. Viruses enter a living cell and insert portion of their DNA or RNA
into the host cell, allowing the host cell to reproduce even more viruses through the processes of transcription and translation of the cell. Each type of
viruses tends to be very specific: they target only specific type of cells in the body. Even though development of cancerous tumors from viral
infections may take years or even decades, they are still causing thousands of deaths annually (Liao 43).
A tremendous portion of human cancers are associated with viral infections: "The estimated total of infection–attributable cancer in the year 2002 is
1.9 million cases, or 17.8% of the global cancer burden. The

Streptococcus pneumoniae– Is a Gram–positive bacterium in the shape of a slightly pointed cocci. They are usually found in pairs as diplococci.
Streptococcus pneumoniae are alpha hemolytic bacterium. Streptococcus pneumoniae have a polysaccharide capsule that acts as a virulence factor for
the organism; along with surface proteins that prevent the activation of complement pathways, and pili that enable S. pneumoniae to attach to epithelial
cells in the upper respiratory tract. Streptococcus pneumoniae lacks catalase and ferments glucose to lactic acid, like most other streptococci. However,
unlike most other streptococci, it does not display an M protein and it hydrolyzes insulin, which help distinguish it from other streptococci.
Streptococcus pneumoniae is the most common cause of meningitis in adults and young adults throughout the world and is best known for causing
pneumonia all other the world.

Summary Of Gammaherpesvirus
PROJECT SUMMARY The gammaherpesviruses Epstein–Barr virus (EBV) and Kaposi's sarcoma herpesvirus (KSHV) establish lifelong persistent
infection in the host and are capable of causing several lymphomas and neoplasms. Gammaherpesviruses have two distinct phases in the life cycle: lytic
replication and latency. Lytic replication is cleared by the immune system, the virus evades detection by the immune system and maintains a lifelong
persistence in the host by establishing latency. Viral latency in B cells is the critical event associated with tumorgenesis. The innate immune system
employs the Type I Interferon (IFN) response to combat viral infection. IFN family of cytokines signals the presence of an intracellular infection and
activates the transcription of IFN stimulated genes (ISGs). ISG products are a diverse collection of proteins that promote antiviral and
immunomodulatory functions. This proposal... Show more content on Helpwriting.net ...
Much of the work characterizing the immune response to KSHV and EBV has been done in vitro. A critical barrier in the gammaherpesvirus field is
the lack of an in vivo immune system to study KSHV and EBV infection in the laboratory. To investigate how gammaherpesviruses interacts and
modulates the immune response in vivo, a closely related murine gammaherpesvirus, MHV–68, is used as a laboratory model system. MHV–68
consists of 80 genes and is genetically more homologous to KSHV than EBV. 60 open reading frames (ORFs) in MHV–68 are homologous to KSHV.
The replication lifecycle of MHV–68 mirrors human herpesviruses, with primary lytic infection in the lungs, latency establishment and maintenance in
the spleen, and viral reactivation mechanisms. While lytic replication is resolved, the virus is able evade immune detection and persist in the host by
establishing latency. Viral latency in B cells is the critical event associated with

Epstein Barr Virus ( Ebv )
INTRODUCTION Epstein–Barr virus was first discovered in 1964 by Sir Michael Anthony Epstein and Ms. Yvonne Barr. They located it in a Burkitt
lymphoma cell line. It was the first virus to be associated with cancer. Infection of Epstein–Barr (EBV) is extremely widespread. The National Institutes
of Health estimates that roughly 95% of people carry the virus. The virus was later found to cause infectious mononucleosis. Mononucleosis has since
been nicknamed the "kissing disease". Transmission is spread orally, primarily through saliva. Healthy people are able to spread the virus to uninfected
people through kissing or sharing food. The virus remains dormant in the body throughout life. For the most part, EBV presents no serious
complications other than the cold–like symptoms and glandular fever related to mononucleosis. However, a growing body of evidence indicates that
many cancers are directly attributable to EBV. It is also known to play a significant role in the incidence of certain autoimmune and blood diseases.
ETIOLOGY
Epstein–Barr Disease (EBV) is known as Herpes Virus 4 (HHV–4). HHV–4 belongs to the gamma–herpes viruses family. EBV is distinct to B
lymphocytes. Latency is often present in lymphoid tissue. EBV DNA "may persist lifelong in an episomal form in the host carrier cells (mainly in
lymphocytes but also in macrophages, in non–hornifying squamous epithelium and/or in blood vessel endothelial cells)." (Rajcani)

diseases such as chicken pox, shingles, multiple sclerosis, infectious mononucleosis, and Burkitts lymphoma which is one of the human cancers. More
than ninety percent of the adult population have artificially acquired immunity
The portal of entry is the respiratory tract. The virus survives in the infected cells of humans, and causes an infection to the B cells which are located in
the lymphoid tissues near the tonsils. Serology tests that can detect that the IgM EBV antibodies are positive for EBV virus are used. Signs and
symptoms include, fever, sore throat, swollen and tender cervical lymph nodes, and extreme fatigue. Prevention should include the treatment of
symptoms and avoiding strenuous activity because there is an increased risk of spleen rupture.

Symptoms of Mononucleosis
Mononucleosis Symptoms Mononucleosis is an infectious disease caused by the Epstein–Barr virus (EBV), which infects the cells in an individual's
throat, and an individual's immune system (Deckler et al., 2009). Mononucleosis gets its name from the high number of white blood cells in the
blood of an infected person, which are called mononuclear cells (Deckler et al., 2009). People infected with EBV carry the virus in their saliva.
Symptoms The symptoms of Mononucleosis are as follows, according to the MayoClinic (2012): Fatigue/Exhaustion Overwhelming feeling of
malaise Sore, irritated throat, such as a strep throat that doesn't respond to antibiotics Fever Swollen/enlarged/sore lymph nodes in neck and
armpits Swollen tonsils Headache/migraine Skin rash or otherwise irritated skin Soft, swollen spleen A person suffering from mono who has a
swollen spleen must be very careful to avoid physical activity or any sports which could cause a rupture to the spleen (Deckler et al., 2009). This
type of precaution is truly important as, resuming normal activities can be done within a few days, but all forms of exercise and one should really
wait at least a month for the safety of the spleen. While the sore throat and swollen tonsils may last just a few days or a week, the sense of extreme
fatigue will last at least a few weeks (Deckler et al., 2009). Mode of Transmission As stated earlier, individuals carry the virus in their saliva, which
means that it can be

Mononucleosis is a disease that is spread from person to person. It is commonly referred to as "mono" and "the kissing disease". It often occurs in
adolescents from the age of fifteen to seventeen. Mononucleosis is a viral infection that can cause fever, sore throat and swollen lymph glands. It is
passed on by saliva and close contact. It was discovered in the late nineteenth century. It was not always referred to as mononucleosis and did not
receive that name until around 1920. The virus, Epstein–Barr Virus, that causes Mononucleosis is relatively large in size. It is something that stays in
your body due to cell memory. It is not always active and cannot always cause for a flare up of the disease. When diagnosing this disease doctor's

When going to a doctor for suspected Mononucleosis a simple test is needed. The first test is a simple evaluation. This is done by simply looking at
the patient. The doctor is looking for signs such as a skin rash, swollen tonsils, and swollen liver or spleen. After doing this simple test the doctors
will draw blood. Mononucleosis leads to an elevated white blood cell count. The mononucleosis spot test looks for two specific antibodies that are
associated with this disease. An antibody titer helps to tell if the Epstein– Barr Virus infection in the patient is current or not. It measures the number of
the antibodies present against EBV in blood, which test can determine if the antibodies are unknown or have been around for a long time. There are
many simple treatments that will help with this Mononucleosis, which relieve the symptoms of this disease. Thus include drinking plenty of fluids,
gargle with warm salt water, to ease the sore throat. Mononucleosis can cause fatigue. Acetaminophen or ibuprofen should be taken to ease the pain.
Since the spleen is swollen no contact sports or anything that could rupture the spleen are contraindicated (Medline Plus, Center of Disease Control)

Most commonly known as "the kissing disease", Mononucleosis or "Mono" is a serious and contagious virus. Mononucleosis is a condition where
there is an unusual profiteration of the lymphocytes in the blood, due to an infection with the Epstein–Barr virus. The (EBV) Epstein– Barr virus is a

Lymphoma's and Nasopharyngeal. Some of the symptoms of "Mono" are often confused with strep throat. But because of the severe sore throat, it
often prompts the patient to call the doctor and get in for a visit. Some of the most common symptoms of Infectious Mononucleosis are: a general lack

These tests rely on our immune system and it's measurable anti–bodies against the (EBV) Epstein–Barr virus. Unfortunately that is not able to be
done until the patient has had the virus for 2 to 3 weeks. The doctor will need to ask several questions and examine the patient. Once the blood tests
are done, the results will help the doctor rule out any other causes of the patient's symptoms. Once detected Mononucleosis can live in ones saliva for
up to 18 months. One thing about this virus is, once you have tested positive for "mono" our body builds up an antibody against the Epstein–Barr
Virus. Although patients have stated that with this virus making you feel so terrible, that ,there must be some kind of antibiotic that is needed to
get better. However, self care is usually all that is needed. Of course, getting plenty of rest is important with most sickness, but with mono that is all
you will seem to do for the next 4 to 6 weeks. Gargle with salt water and warm water. That will help your sore throat and swollen tonsils. Make sure
to get some throat lozenges to help sooth your throat as well. It is also helpful to take some acetaminophen (like Tylenol) or ibuprofen (like Advil) to
reduce fever and helps relieve the sore throat that was mentioned above. If possible only rest, nourishment, and water are the best way to get through
this virus. The medications above are not needed to improve they are only

There was no significant trend amongst many of the toxicity endpoints and RILA irrespective of CMV serostatus. However, there was a significant
trend in relation to urinary STAT and RILA predictive power. It is noteworthy that the RILA assay shown to predict urinary STAT within this cohort
population. Interestingly, when the dataset was split based on CMV serostatus, however, urinary toxicity was not observed in CMV seropositive
patient despite an increase number of cells undergoing apoptosis as assessed by RILA . This implies CMV infection in this cohort of prostate cancer
patients protects against toxicity (i.e. these patients were hyposensitive to toxicity – CMV seropositive patients were at a minimal risk of suffering
toxicity). This trend is in opposition to what was observed amongst CMV seropositive BC patients. Neote et al. (1993) found elevated levels of
CMV IgG preceded the development of breast cancer in a Norwegian cohort. This might be the reason why CMV seropositive BC patients had worse
toxicity. CMV infection in BC patients might be involved in tumour progression. Oseguera et al. (2017) study found elevated CMV levels in the serum
of some BC patients correlated with poor prognosis. CMV infection was associated with promoting malignant spread of BC cell.
This study was subject to a series of limitations. First, BRCA1 and BRCA2 mutations were not accounted for in this cohort population as these

United States alone, it has shown previous infection in about ninety to ninety five percent of all adults. (Weller, 2003). It is also one of the eight
main human herpes viruses as well as the cause of another disease called mononucleosis. Mononucleosis is a kind of infection that is generated
through kissing or sharing the same saliva. Occurrences vary from drinking from the same glass or using the same toothbrush as someone who is

The Epstein–Barr virus is part of the Herpesvirales Order. Following order, this viruses Family is the Herpesviridae. What this term means is that the
viruses nucleic capsid is liner and has a double stranded DNA. It is also composed of an icosahedral capsid and it is surrounded by an envelope which
is rich with phospholipids. The Epstein – Barr virus also is classified with a Subfamily termed Gammaherpesvirinae. The virus is specific to
T–lymphocytes or B–lymphocytes as well as attacking the lymphoid tissues of vertebrae's. Moreover, the Genus is named Lymphocryptovirus because
it only infects cells in humans and monkeys. The Species is the Human Herpesvirus 4–. This translates into a kind of virus that infects humans only and

pathogens. Kaposi sarcoma (KS) is a cancer that develops from the cells that line lymph or blood vessels. It usually appears as tumors on the skin or
on mucosal surfaces such as inside the mouth, but tumors can also develop in other parts of the body, such as in the lymph nodes (bean–sized
collections of immune cells throughout the body), the lungs, or digestive tract. KS can cause serious problems or even become life threatening when
the lesions are in the lungs, liver, or digestive tract. KS in the digestive tract, for example, can cause bleeding, while tumors in the lungs may cause
trouble breathing. A person infected with HIV (that is, who is HIV–positive) does not necessarily have AIDS. The virus can be present in the body for
a long time, often many years, before causing major illness. The disease known as AIDS begins when the virus has seriously damaged the immune
system, which results in certain types of infections or other medical complications, including KS. When HIV damages the immune system, people
who also are infected with a certain virus (the Kaposi sarcoma associated herpes virus or KSHV) are more likely to develop

Mononucleosis Research Papers
Emma Johnston Ms. Phelps Health Period 5 October 12, 2016 Mononucleosis Infectious Mononucleosis, commonly known as mono, is an infectious
disease caused by the Epstein–Barr virus (EBV). The EBV virus causes an increase in lymphocytes (large white blood cells) in the blood stream due
to viral infection. Although scientists are not certain when the first case of mono occurred, the most accurate record was written in 1889 by Dr. E.
Pfeiffer. The term Infectious Mononucleosis was first introduced in 1920 by British researchers Thomas P. Sprunt and Frank A. Evans in replace of its
original term Glandular Fever. By 1964, the Epstein–Barr virus was successfully identified and named by doctors M. Anthony Epstein and Ms. Yvonne
Barr. Mono's nickname "The Kissing Disease" comes from its ability to transfer by human contact with saliva. This, however, is not particular to just
kissing. Mono can be transferred through anything that has touched the saliva of anyone infected by it. Things such as sharing chapstick or lipstick,
straws, utensils, or cups can transmit the virus. Even sneezing or coughing in a close radius can transmit the disease via droplet. Mono is most
common in people ages 15–25, and is at it's prime during high school years. Cases of... Show more content on Helpwriting.net ...
Doctors may often advise people diagnosed with mono to stay in bed, limit activity, drink lots of fluids, and use a throat lozenge––or gargle with salt
water––to sooth a sore throat. Nonsteroidal anti–inflammatory and analgesic drugs (such as Ibuprofen, Advil, and Tylenol) can be bought over the
counter as pain relievers and fever reducers. Mono symptoms usually die down at around 1–4 weeks, but the person may still be infected with the EBV
virus for up to two months. However, there is a small percentage of people whose immune systems are unable to completely fight off mono. As a
result, some people may develop CFS (Chronic Fatigue Syndrome) due to the EBV

Medical Case Study
As the head physician at Johns Hopkins University Center Infirmary, I must inform you of an urgent matter regarding the presence of four different
diseases that hold the potential for an outbreak on your campus. These four diagnosed diseases are meningococcal disease, Epstein–Barr virus,
streptococcal pharyngitis, and influenza virus B. Currently, nine students are independently affected by one of these illnesses and if the campus does
not take precaution immediately, the number of infected students can quickly double within a day.
Found to be the most prevalent disease of the four, meningococcal disease, also known as bacterial meningitis, was diagnosed in four of the campus'
students. It was first diagnosed by DNA sequencing through ... Show more content on Helpwriting.net ...
The second disease was the Epstein–Barr virus, which is also known as mononucleosis, that infected two students on campus. For diagnosis, DNA
sequencing through BLAST was also used to detect the pathogen's existence in one of the patients. However, since the laboratory was unable to obtain
a sample from the second patient, the clinic deduced their infection by determining their relationships. The symptoms that accompany this illness
include a fever, sore throat, headaches, fatigue, and swollen lymph nodes. Since the pathogen, Human herpesvirus 4 (HHV–4), for mononucleosis is a
virus, the patients were instructed to rest and antiviral medications were prescribed. Antiviral drugs, unlike antibiotics, function similarly to pain killers
as the viruses cannot be targeted and destroyed the way that bacteria can, therefore, advising that the patients rest and recover allows for their immune
system to gradually fight off the viral infection. As the pathogen is able to be transmitted through bodily fluids, students are advised to avoid sharing
foods and drinks with other students and maintain overall good hygiene, which includes regularly washing their hands.
Strep throat claimed one of the students on the campus, which was determined again through DNA sequencing. With strep throat, individuals typically
have a sore throat, fever, headaches, swollen tonsils and/or lymph nodes, and overall body soreness. The

Infectious Mononucleosis
Infectious mononucleosis, or mono, is called "the kissing disease" because that is one of the ways you can get it. Mono occurs in about 1 in every
2,000 people every year. Mono is caused by Epstein–Barr virus, EBV for short, which affects nearly every person at some point in his or her life. In
this essay, you will learn the signs and symptoms, the treatment options for, and the prognosis of infectious mononucleosis. Infectious mononucleosis
most often occurs in people between the 5 to 25 years of age, with the highest occurrence rate being between 15 to 25 years of age. Universities are the
hot spot for contractions of mononucleosis each year. Epstein–Barr virus is carried in the salivary glands and is spread by direct intimate contact

Viruses : A Small Organisms And Most Viruses Essay
Viruses are known to be very small organisms and most viruses cannot be seen with an ordinary microscope. They are comprised of a little
number of qualities as DNA or RNA encompassed by a protein covering. A virus must enter a living cell and "commandeer" the cell 's hardware so
as to duplicate and make more viruses. Some viruses do this by embedding their own DNA (or RNA) into that of the host cell. At this point the
DNA or RNA influences the host cell 's qualities and can push the cell toward becoming cancerous (American Cancer Society). There are several
ways that a virus can cause cancer. Some viruses can cause chronic inflammation. The chronic inflammation that is brought on by the virus is
when there is an increase in the cell division. By the cell division increasing and making new cells to replace damaged cells, usually results in the
risk that a genetic mutation will take place. Therefore, inflammation caused by some of these viruses leads to increase cell division, which leads to
a greater chance that errors in genetic material will take place and will eventually lead to cancer. There are also some viruses that may directly
damage the DNA within the cells causing them to result into cancer and alter the immune system, so that it is less able to fight off cancer cells
(Fayed). According to The National Cancer Institute, cancer is the name given to a collection of related diseases. In all types of cancer, some of the
body's cells begin to divide without stopping

Epstein Barr Research Paper
Epstein–Barr Virus, also known as human herpesvirus type 4, is a common infectious virus that will affect greater than 85% of the population at least
once in their lifetime. The virus was first discovered by, and named after, Sir Michael Anthony Epstein and Yvonne Mr. Barr in 1964 in the midst of
researching a case of Burkitt's lymphoma. The Epstein–Barr virus is predominately found in a host's saliva, and is transmitted through direct and
indirect contact with the infected person's bodily fluids. Epstein–Barr virus (EBV) is responsible for numerous infections that can take place throughout
the body, most commonly acute infectious mononucleosis. Infectious mononucleosis, simply referred to as "mono," is an illness that is directly caused
by the Epstein–Barr virus and can frequently affect toddlers, teenagers, and adults. EBV, along with infectious mononucleosis, is primarily spread from
person to person orally through the following acts: kissing, sharing food and drinks, and coming in contact with contaminated objects, such as
toothbrushes. ... Show more content on Helpwriting.net ...
Antibiotics are not usually prescribed to those infected because they are considered an ineffectual treatment of Epstein–Barr virus and its secondary
virus, mononucleosis. However, over–the–counter medications such as acetaminophen can be taken, but will only reduce fever and pain associated
with symptoms and will not treat the virus itself. Those in the recovering stage will be instructed by a physician to get a sufficient amount of sleep,
stay hydrated, and use pain relievers for any pain and fevers that may arise. Confirmation of Epstein–Barr Virus can come from a "mono spot" test and
complete blood count (CBC) testing if the mono spot test produces a negative result. Typically, a physician will check for any red dots or noticeable
white patches on the oropharynx and soft palate areas during an

HodgkinвЂ™s Disease Essay
Hodgkin's Disease
Cancers arising from the lymph nodes or other sites of lymphoid tissue are broadly termed lymphomas. This group of diseases is divided into
Hodgkin's disease and non–Hodgkin's lymphoma. In both conditions, there is a replacement of normal lymphatic tissue by collections of abnormal
lymphoma cells.
The lymphatic system are a complex network of specialised cells and organs that defend the body against infection. Lymphatic organs include the bone
marrow, spleen, thymus gland, lymph nodes, tonsils, adenoids, appendix and clumps of tissue in the small bowel. A function of the lymphatic system is
to nurture and mature the B and T–lymphocytes (white blood cells vital to immune function). Cancerous changes can take place ... Show more content

In some instances, the nodes may spontaneously increase and decrease in size.
Because Hodgkin's disease is associated with a defect in the maturation of the lymphocyte, the immune system may be impaired. As such repeated
infections may occur. Symptoms
The symptoms of Hodgkin's disease frequently depend upon the stage of disease. Staging defines the extent to which the disease has spread throughout
the body. Moreover, it often determines which treatment(s) will be required.
Hodkins has 4 distinct stages of Hodgkin's disease, these being stages 1–4. Each stage is further defined as exhibiting either A or B symptoms. These
symptoms refer to either the absence of A or presence of B unexplained weight loss in the preceding 6 months, fever greater than 38В°C, and or night
sweats.
Tumour suppressor genes: In health this family of genes usually act as a counter balance for oncogenesis. It is thought that they may be responsible
for repairing gene damage in cells, or are growth inhibitor genes. In Hodgkin's disease, there are often evidences of mutation in tumour suppressor
genes as well as other genes.
Stage 1.

Stage 1 Hodgkin's disease affects a single lymph node or lymph node region. The lymph nodes most commonly affected are the nodes in the neck,
armpits or groin.
Stage 2.
Stage 2 disease is associated with lymph node involvement in 2 or more regions. However, the nodes must be involved in only one side of the

Name: Jade Dufren
Causative Agent: Epstein–Barr virus
Disease: Burkitts lymphoma, Mononucleosis, and Orchitis
Classification of the causative agent:
Human Herpesvirus 4 (HHV–4) – Gammaherpesvirinae enveloped virus.
History:
The Ebstein–Barr Virus took on the name of its founders, Anthony Epstein, Yvonne Barr, and Burt Achong in 1964. It is a part of the herpes family,
but has no relation to the genital or oral types of herpes. Although it was first recognized in children, about 90% of the human population all over the
world between infancy to old adulthood is infected with the virus. It is most popular for causing mononucleosis, short for mono, which a lot of

This disease can cause several secondary infections including strep, sinusitis, and pneumonia that involve damage to the immune system. In some rare
circumstances, it can evolve to Guillain–BarrГ© syndrome which can lead to death.
In some rare cases, EBV can be associated in causing the secondary infection orchitis, which symptoms include inflammation of the testicles.
Treatments:
There is no cure for EBV, only medications to relieve the symptoms such as anti–inflammatory and steroids. People can also take vitamins to make
their immune system stronger so the virus has a less chance of taking over. There are also anitviral medications for people to take to help symptoms
flaring up such as acyclovir. A doctor may prescribe plenty of bed rest and fluids while experiencing symptoms.
Prevention:
It is very difficult to prevent EBV since a lot of people infected are not even aware they have the virus. There is no vaccine against the virus, but
people can always make sure not to share drinks, utensils, or eat after each other. Hand washing, good hygiene, and avoid kissing strangers. Protective
sex is never 100% effective but can lessen the chances of a person becoming

Essay On Odontogenic Etiology
There are numerous conditions which could result in the pain experienced by a patient who reports a "toothache". Many times, an odontogenic
etiology–such as caries, cracked tooth, infection, or periodontal abscess–for the pain can be identified, treated, and resolved. However, in some cases,
there is no odontogenic etiology for the pain, requiring a more complicated differential diagnosis. After eliminating the possibility of odontogenic
conditions by examination, radiography, and pulp tests, several other conditions should be considered.
Fungal and viral infections can both cause orofacial pain. One common fungal infection of the mouth is Candida albicans, whose symptoms typically
include white patches or plaques on the mucosa or tongue (SOURCE). Viral infections such as Herpes virus and Epstein–Barr virus ... Show more

Trigeminal neuralgia is a chronic neuropathic pain conditions which typically causes numbness, pain, and/or burning in the area around the trigeminal
nerve (NINDS, 2013). In patients with trigeminal neuralgia symptoms, careful questioning about any concurrent health issues or symptoms may allow
diagnosis of an underlying systemic causes, such as neoplasm or multiple sclerosis (Dumas, 1999), which may require referral to an appropriate
specialist. Fibromyalgia is another neuropathic pain condition, which results in symptoms including chronic, widespread pain, hyperalgesia, fatigue,
and sleep problems; additionally, this condition has a high comorbidity rate with irritable bowel syndrome, depression, and anxiety disorders (Jin,
2014). One condition that can be misdiagnosed as fibromyalgia is myofascial pain. Myofascial pain and fibromyalgia both involve trigger points;
however, unlike the former, myofascial pain involves asymmetrical pain in a taut muscle band. Myofascial pain may also be misdiagnosed as
odontogenic pain, so it is important to assess radiographic exams, trigger points, and symptoms

Gamma Herpes Virus (EBV)
EBV (Epstein Barr Virus) also known as Gamma herpes Virus– 1, is amongst a large family of approximately 100 herpes virus, 8 of these are known
to infect humans. These are Cytomegalovirus, herpes simplex virus –1 and –2, varicella–zoster virus, human herpes virus 6 (variant A and B), human
herpes virus 7, kaposi's sarcoma (human herpes virus 8) and EBV (gamma Herpes Virus –1). All of these are classified into 3 different subfamilies
known as alpha, beta and gamma dependant on the specificity of cell host range and tropism. The alpha group includes Herpes simplex virus –1 and
–2, and Varicella–Zoster Virus and can be described to have a broad host cell range, a short reproductive cycle in epithelial cells and efficiently spreads
well in culture. ... Show more content on Helpwriting.net ...
Beta Herpes subfamily consists of CMV (cytomegalovirus – HHV–5) also classified along with HHV–6 and –7 (Human Herpes Virus –6, –7); HHV–5,
–6 and –7 have similar genetic homology. The beta subfamily has a restricted host range in vitro, except in vivo where few types of cells including
monocytes, lymphocytes and epithelial cells can be the site of replication; HHV–6 and –7 tend to target T–lymphocytes and latently infect lymphocytes
(lymphoreticular cells), secretory glands and kidneys. The focus is on the Gamma subfamily which includes Kaposi's sarcoma – Herpes Virus (KSHV
– HHV8) and EBV (HHV4), usually known to infect epithelial cells in the oral cavity, gamma herpes sub family latently infect B–lymphocytes to
prolong infection and further spread in the host. EBV targets B–cells in the pharynx (nasopharnyx) leading to division of

Mononucleosis is defined as, "a vial infection caused by the Epstein–Bart virus (EBV), which is part of the herpes family of viruses." (Beaman).
Mononucleosis is often referred by one of two names: mono or the kissing disease. This infection is typically spread via saliva, so it is important to
not and drink after other people, and when someone is in a relationship. It is most common in young adults in the age range of 15–24 years of age. The
prevalence rate of mononucleosis is over 95%. Once a person has this infection, it takes a while for the results to go back to negative. The signs and
symptoms of mononucleosis can take approximately four to eight weeks to first appear. These symptoms include: swollen lymph glands, fever, sore
throat,

Multiple Sclerosis Research Paper
Multiple sclerosis (MS) is a chronic inflammatory disease that affects the nerve and nerve fibers of the central nervous system (Ringold, Lynm, &
Glass, 2006). It results in the loss and damage of myelin, the insulator of nerve fibers, thus affecting the conduction of nerve signals within the brain
and spinal cord. This damage to the central nervous system (CNS) leads to an impairment in sensory, cognitive, and motor functions of the body. The
cause of multiple sclerosis is still unknown, however, it is known that environmental, genetic, and viral factors play a role in the spread and diagnosis
of this disease. This essay will examine the likelihood of the Epstein–Barr virus as an indicator to the development of multiple sclerosis.

The acquisition of an infectious agent like EBV is more likely to occur during a specific window of weak immunologic functioning such as childhood
(Alotaibi et al., 2004). The diagnosis of multiple sclerosis at such a young age further emphasizes the similar environmental and genetic factors that it
shares with EBV.
A study conducted by Alotaibi et al. (2004) compared the serological evidence of EBV in children with MS and their healthy peers without MS. Of
the children with MS, data showed that 83% traced some sort of remote EBV infection. Whereas, the control group of healthy children showed only
42% of present EBV antibodies. The data further showed that there was no correlation to MS when tested for other virus' such as parvovirus B19,
cytomegalovirus, and varicella zoster. This evidence supports the genetic etiology of multiple sclerosis. During childhood and adolescence, 50% of
individuals contract an EBV infection, and 5% of these individuals go on to develop multiple sclerosis. Although these numbers may seem minuscule,
the majority of children with MS show a prior exposure to EBV, compared to their healthy peers who have yet been exposed to the

Epstein-Barr Virus Lab
The Epstein–Barr Virus is part of the herpesvirus family and was the first virus discovered to cause a human cancer. The virus has two stages of its
life cycle, the latent phase, which allows the virus to lie dormant within a cell and the host and the lytic phase where the virus reproduces and spreads
among cells. Haloperidol (HPD), a common mood stabilizer, aids in the initiation of the lytic cycle. Administering the Haloperidol at varying
concentrations and exposure lengths will test what is the best time and concentration that will activate viral gene expression. Quantitative polymerase

The HH514–16 Burkitt lymphoma B cell is a cell line used that is infected with the Epstein–Barr Virus. Cells are grown using RPMI 1640 medium
containing 8% fetal bovine serum; a supplement contain low level of antibodies and growth factors. Quality and quantity of the cells are measured by
counting the number of alive and dead cells under a microscope and also noting shape, size, and arrangement. After, the cells are then cultured and
treated with Haloperidol (HPD) at varying concentrations or exposure times. Exposure times are marked when the cells are frozen and stored in
negative 80 degrees celsius. RNA is then isolated from the cells using a Promega kit. RNA concentrations are measured using a Nanodrop and then
appropriate dilutions are achieved to ensure unified sample concentration. iScript reverse transcriptase generates a strand of complementary DNA from

CFS, otherwise known as chronic fatigue syndrome, is this illness characterized by debilitating fatigue. At times, this disease is also referred to as

One can simply become tired, while others may be totally bedridden and disabled from fatigue. Sometimes the body is better, so the individual can
lead an almost normal lifestyle, but then days or weeks later this strength may easily wane.
The true cause of this illness is not yet known. Several studies in the 1980's tried to link CFS with the Epstein–Barr virus (CFS pamphlet). This virus
is one in the family of herpes viruses, and EBV infection are almost inevitable in all humans. However, more recently it has been found that some CFS
patients lack the EBV antibodies, which means they never had this virus (Bell, 1994). Therefore, there has been no consistent link found between
elevated EBV antibodies and the presence of CFS.
Other viruses have been associated with CFS as well. In the published research results (Holmes, et al, 1988) findings suggest that the recently
discovered herpesvirus–6 (HHV–6) is higher in patients with CFS than in control groups. The higher level of HHV6 does not necessarily suggest that
this viral activity is occurring, but may demonstrate immune responses to various stimuli. Although it is possible that HHV–6 may be a factor in CFS
sufferers, it cannot be proven with the current antibody testing.
Though this remains an area of great controversy, the psychological factors influencing those diagnosed with chronic fatigue must be considered as
well. Many

Hepatitis B And Its Effects
Hepatitis B is a genuine liver disease created by the hepatitis B virus (HBV). For some individuals, hepatitis B contamination gets to be incessant,
which means it keeps going over six months. Having unending hepatitis B builds your danger of creating liver disappointment, liver disease or
cirrhosis which is a condition that causes lasting scarring of the liver. A great number of people contaminated with hepatitis B as grown–ups recuperate
completely, regardless of the possibility that their signs and side effects are extreme. Babies and youngsters will probably build up a ceaseless hepatitis
B contamination (MayoClinic).
Hepatitis C contamination additionally expands the danger of creating liver disease just like hepatitis B. Until the 1980 's, hepatitis C virus (HCV) was
known as non–A non–B hepatitis. The underlying disease may have side effects, yet a critical number of individuals don 't have side effects. Not at all
like hepatitis B, in which the ailment does not frequently get to be constant, have around 80% of individuals with hepatitis C built up an endless

Immune Complicated Disease: Multiple Sclerosis
Multiple sclerosis, or MS as it is more commonly referred, is an immune mediated disease that involves the body's own defense mechanism, specialized
immune cells, that ultimately attacks the central nervous system. Specifically, the myelin protein that coats axons and forms an electrically insulating
layer for quicker processing of the nervous system, is attacked by cytotoxic cells that have crossed into the CNS. In a healthy patient, the blood brain
barrier cannot be crossed by cytotoxic cells and it is speculated that an environmental component or outside source mediates this crossing. When the
myelin is attacked, it forms scars in the CNS, as multiple sclerosis literally translates to "many scars," which is the direct result of the disease. The scars
disrupt the normal nerve impulses that travel through the central nervous system, and can cause a variety of symptoms including loss of cognition,
fatigue, or numbness in the body (Evidence). ... Show more content on Helpwriting.net ...
While this may sound like an autoimmune disease, scientists are still unsure about what antigen the immune cells are attracted to attack, meaning it is
"immune–mediated" as opposed to "autoimmune" (Evidence). This, like many components to MS, remains a mystery, and researchers are still
discovering and advancing what we know about the disease.
When I received your letter, I made sure to research MS more in depth to provide you with as much information on the root cause of MS, as science
will currently allow. As I mentioned, this disease remains partially a mystery but with new scientific breakthroughs, it is becoming more clear that a
