Microorganisms Vaccine And Antibiotics
Vaccines work by introducing a small, weakened amount of a virus or bacteria into the body to trigger an immune response and develop antibodies without causing illness. They are designed using different strategies depending on the pathogen, including weakening or inactivating viruses and neutralizing bacterial toxins. Antibiotics, meanwhile, are drugs that treat bacterial infections by killing or stopping the growth of bacteria.

Microorganisms Friends and Foe Part 3
Viruses are microscopic organisms that can only reproduce inside host cells. They come in various shapes and sizes and can infect animals, plants, and bacteria. Useful microbes are used in food/beverage production, medicine, vaccine production, and environmental cleanup. Harmful microbes can cause communicable diseases in humans and plants via air, water, food, or contact. Antibiotics are drugs that kill germs and cure infections, while vaccines protect against diseases by triggering antibody production without causing illness. Proper vaccination prevents diseases like cholera, hepatitis, smallpox, and tuberculosis.

Defining Emerging infectious diseases (EIDs) as a disease that are new or changing and are increasing or have the potential to increase in incidence in the near future then these changing diseases turn in some way uncontrollable for science. Coping with such evolving and changeable existing organisms have turned into an inextricably challenge to Science. According to Microbiology textbook it references some of the factors that have contributed to the development of EIDs are evolutionary changes in existing organisms, the spread of known disease to new geographic region or population by modern transportation, and increased human exposure to new, unusual infectious agent in areas that are undergoing ecological changes such as deforestation and construction; but also AIDs developed as a result as antimicrobial resistance.
Examples of EIDs given in the textbook we have Avian Influenza A (H5N1) or bird flu. This type of flu is most often contracted by contact with sick birds; these viruses occur in birds worldwide. It can also be passed from animal to animal, animal to person and person to person. The outbreak came in 2003 in southeast Asia when it killed millions of poultry and 24 people. However, a different Avian influenza virus(H7N9) sickened 131 people in China, but no death was reported. Reported as of 2008 Avian Influenza had sickened 242 people, and about half of them died. The virus has not yet evolved to be transmitted successfully among humans but still under monitoring due to its power to mutate and spread. Another example is Bovine spongiform encephalopathy (BSE) is a neurodegenerative disease of cattle caused by misfolded proteins known as prions. Symptoms include abnormal behavior, trouble walking, weight loss, and eventual paralysis. The outbreak came across 1986 when microbiologists’ studies suggested that the main source of disease was a cattle feed prepared from sheep infected with their own version of the disease. Cattle are herbivores but adding protein to their feed improves their growth and health. Some steps we can take in order to prevent any outbreak of these diseases described above, first you have to understand how those diseases are transmitted; it means get educated in topics related to it in order to avoid getting sick. Good personal hygiene like wash your hands regularly, before and after every action you take, cover a cough, do not share personal utensils like dishes, glasses, combs, spoon, forks and so on. Practice good food-safety techniques to avoid getting sick like wash produce, rinse meats, do not eat raw food. Adults and children should make sure their vaccinations are up to date. If you are traveling to an area where insect-borne disease is present, take and use an insect repellent containing DEET. In many tropical regions, mosquitoes can carry malaria, dengue, yellow fever, Japanese encephalitis, or other seri ...
B iotechnological potential of viruses
This document discusses the biotechnological potential of viruses. It describes how viruses can be used for biological pest control by infecting target pest species. It also explains how viruses are used to develop vaccines by using weakened or killed viruses to produce immunity. The document outlines different types of gene therapy that use viruses as vectors, including ex vivo and in vivo gene therapy. It also discusses how bacteriophages can be used for bacteriophage therapy to selectively target and destroy pathogenic bacteria.
Changing Pathogens
The document discusses antibiotic resistance and how it develops through natural selection. It explains that when antibiotics are used, only bacteria that are resistant to the antibiotic will survive and pass on the resistant genes. This can lead to epidemics if the bacteria become resistant to multiple antibiotics. The document also discusses the H5N1 bird flu virus and efforts to develop a vaccine against it.
1.5 ways to prevent infections
There are several key ways to prevent infections caused by microorganisms, including controlling vectors like mosquitoes and houseflies, sterilization using heat, chemicals, or radiation, and immunization. Vectors can be controlled by covering food, disposing of waste properly, using insecticides, and cleaning areas where larvae may live. Sterilization aims to kill pathogens through processes like applying steam, chemicals like antiseptics and disinfectants, or radiation. Immunization stimulates the body's immune system to produce antibodies to fight pathogens by exposing it to weakened or dead forms of viruses and bacteria typically through vaccines.

Infectious diseases 13.1
Infectious diseases are caused by pathogens like bacteria, viruses, fungi, protozoa, and parasites that can be passed from one living thing to another. Common examples are influenza, strep throat, and athlete's foot. Pathogens are spread through various methods like person-to-person contact, contaminated food/water, animals, and surfaces. Treatment depends on the type of pathogen, with antibiotics used for bacterial infections and medicines to relieve symptoms of viral infections. Prevention focuses on vaccination, hygiene like hand washing, avoiding sharing personal items, and protection against insect vectors.
diease43.ppt
The document discusses infectious diseases. It outlines Koch's postulates, which provide criteria for determining if a specific agent causes a disease. The main agents that cause infectious diseases are bacteria, viruses, protozoa, fungi and helminths. Diseases can be transmitted through the air, contaminated food/water, body fluids, contaminated objects, or animal vectors. Examples given are the flu, which is caused by influenza viruses, and AIDS, which is caused by the HIV virus. Methods for reducing spread include vaccines, antibiotics, hygiene, mosquito protection and quarantine. Emerging infectious diseases are those recently appearing or increasing rapidly due to new agents, host spread, drug resistance or deliberate introduction.
Viral Diseases in Poultry & Their Management.pdf
Viral diseases in poultry are widespread and fatal for poultry enterprises. Every year outbreaks of bird flu, new castle disease, gumboro & IBH creates havoc in the industry. This document will help in throwing light on overall perspective of viral disease in poultry, use of antibiotics and avian immunology.
plague .pptx
Plague is a disease caused by the bacterium Yersinia pestis that is usually transmitted via flea bites from infected rodents. There are three main forms: bubonic plague causes swollen lymph nodes, septicemic plague can result in bleeding into the skin and organs, and pneumonic plague causes a severe pneumonia that can spread between humans. Symptoms depend on the form but may include fever, chills, coughing, and respiratory failure. Treatment with antibiotics can cure plague if administered early in infection. Prevention focuses on reducing rodent habitats and flea exposure.
Dengue
Dengue is a mosquito-borne viral disease affecting millions of people worldwide each year. It is transmitted by the bites of infected Aedes aegypti and albopictus mosquitoes, which breed in stagnant water. The dengue virus causes flu-like symptoms including fever, muscle pains, and rashes. While most cases are mild, severe dengue can cause potentially lethal complications. Prevention efforts focus on eliminating mosquito breeding sites and reducing exposure to bites. A dengue vaccine was recently approved but more research is still needed.
Harmful Micro-organisms
Harmful microorganisms can cause diseases in humans, animals, and plants. Some microorganisms are pathogens that transmit communicable diseases from infected individuals to healthy ones through body fluids or carriers like insects. Pathogens include bacteria, viruses, fungi, and protozoa that obtain nourishment from their host. Microorganisms show harmful effects by causing most diseases, aside from genetic factors, and by damaging food and sometimes releasing toxins that cause food poisoning. Infections can be prevented through methods like handwashing, antibiotics, competitive microbes, and vaccination.

SC week 8 Viruses.pptx
Viruses are tiny infectious agents that can cause disease in humans. They spread through various means such as respiratory droplets from an infected person, contact with contaminated surfaces or objects, sexual contact, contaminated food or water, and insect bites. Viruses infect and take over human cells to replicate, which can damage or kill cells and lead to symptoms ranging from mild to severe. While there are antiviral treatments for some viruses, treatment for most viral infections focuses on relieving symptoms until the immune system fights off the infection. Proper handwashing, cleaning, food safety, avoiding sick people and insect bites can help prevent viral transmission.
Infectious diseases (communicable).pdf
The document discusses various infectious diseases caused by four main types of pathogens: viruses, bacteria, fungi, and protozoa. It provides examples of major diseases for each pathogen type, including how they are transmitted and prevalent examples like influenza, tuberculosis, malaria, and more. It also discusses vaccines for diseases like measles, hepatitis, and others. Overall, the document serves as an overview of common infectious diseases categorized by the pathogen that causes each disease.
Infections
This document defines and discusses various types of infections. It begins by defining an infection as the invasion of an organism's tissues by pathogenic agents, their multiplication, and the host's reaction. Infections can be caused by viruses, viroids, prions, bacteria, nematodes, arthropods, fungi, and other microorganisms. The document then provides details on the causes, signs and symptoms, diagnosis, prevention, and treatment of infections.
Microbe human interaction
The document discusses various types of relationships between microorganisms such as mutualism, parasitism, and commensalism. It also defines key microbiology terms like infection, disease, pathogenicity, and virulence. Finally, it describes the different microorganisms that normally reside on or inside the human body as well as those that can be present transiently.
Infection disease transmission
Infectious diseases are caused by pathogenic microorganisms like bacteria, viruses, parasites or fungi. They can spread directly from person to person or indirectly through contact with contaminated surfaces or objects. Common signs of infection include fever, fatigue, diarrhea, muscle aches and coughing. Infections are treated using medications like antibiotics, antivirals and antifungals. Preventing the spread of infectious diseases involves practices like hand washing, vaccinations, safely preparing food and practicing safe sex.
Diseases Caused by Viruses_ Khyati Gupta (1).pdf
Viruses cause a variety of diseases that are transmitted through different routes. Common viral diseases include influenza, measles, mumps, rubella, smallpox, rabies, chikungunya, and dengue. Viruses have an incubation period before symptoms appear. Symptoms vary depending on the virus but can include fever, rash, joint pain, and respiratory issues. Some viral diseases may lead to severe complications affecting organs like the heart, brain, or CNS. Antiviral drugs and vaccines exist for some viruses.
Infec 01
This document discusses the basic principles of infection, including:
1. Microorganisms are small living organisms including pathogens that cause disease and non-pathogens that do not cause or can be beneficial.
2. For an infection to occur and spread, certain conditions must be met including: an infectious agent, a reservoir, a means of exiting the reservoir, a mode of transmission, a portal of entry, and a susceptible host.
3. There are various types of microorganisms like bacteria and viruses that can cause infection through different mechanisms and are influenced by factors such as temperature, pH, food, moisture, oxygen, and darkness.

MERCURY GROUP.BHMS.MATERIA MEDICA.HOMOEOPATHY
Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.
The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Recently uploaded (20)
