Scientists create 1st new antibiotic in nearly 30 years
Scientists have discovered the first new antibiotic in nearly 30 years called Teixobactin. It is effective against many common bacterial infections like tuberculosis and C. difficile. Teixobactin works via a novel dual mechanism attacking the building blocks of bacterial cell walls. Testing on mice showed it cleared infections without side effects. This discovery is significant because Teixobactin does not encounter any detectable resistance, which could lead to a new generation of antibiotics. It may be available for human use within 5 years.
ARE WE KILLING ANTIBIOTICS?
Antibiotics are facing their final stage of survival as common bacteria take over in violent opportunistic infections. Hospitals have become hotbeds for spreading antibiotic-resistant infections. The overuse and misuse of antibiotics, both in hospitals and at home, is contributing to the rise of drug-resistant bacteria that are difficult or impossible to treat. If antibiotic resistance continues to spread unchecked, it could lead to widespread healthcare issues and even the end of modern medicine as we know it.
Antibiotics
Antibiotics are substances that kill or inhibit the growth of bacteria. They are important for modern medicine as they allow complex surgeries and treat infections. Most antibiotics are produced in laboratories based on compounds found in nature that microbes use against other microbes. Antibiotics work by attacking bacterial cell walls or interfering with reproduction. They can be bactericidal, killing bacteria, or bacteriostatic, stopping their growth. Common types target a narrow or broad range of bacteria. While antibiotics revolutionized medicine, their overuse and misuse has led to increased antibiotic resistance.
Microbiology concepts
This document discusses microorganisms that cause disease in humans. It identifies the main types of pathogens as viruses, bacteria, protozoa, and fungi. Viruses hijack host cells to replicate and are usually self-limiting, while bacteria come in various shapes and sizes and antibiotics are often used to treat bacterial infections. Protozoa and fungi can also cause diseases like amoebic dysentery and ringworm, respectively, and are treated with special medicines. The development of drug resistance in pathogens is a growing health concern caused by overuse of antibiotics. Identifying the causative organism is important for effective treatment and preventing resistance.
why does bacteria make infections on humans
Bacteria can cause a variety of infections and diseases in humans, such as strep throat and tuberculosis. While some bacteria are helpful in food production, others can be harmful by releasing toxins that damage tissues. Bacteria were first discovered in the late 1600s by Antony van Leeuwenhoek and reproduce by splitting into two or forming spores. They are found nearly everywhere and while mostly harmless, a small percentage can make humans sick.

Some of the major branches of medical microbiology it outlines include general microbiology, immunology, bacteriology, virology, mycology, and parasitology. The document also highlights some of the pivotal early contributors to microbiology, including Antonie van Leeuwenhoek, Edward Jenner, Louis Pasteur, and Robert Koch.
History of plant pathology
Plant pathology is the study of plant diseases. It deals with the causes and mechanisms of disease development, plant-pathogen interactions, and disease management methods. Some key events in the history of plant pathology include the first use of microscopy to observe fungi and bacteria in the 16th-17th centuries, the 19th century discoveries of the fungal causes of late blight and anthrax, and the early 20th century discoveries of viral and other non-fungal pathogens. Modern plant pathology incorporates genetics, microbiology, and other fields to understand and address important diseases.
Resistance with narrations
1) This document discusses how bacteria and insects can evolve resistance to antibiotics and pesticides due to variation, mutations, sexual reproduction, rapid reproduction rates, and selection pressures from human use of these substances.
2) It provides examples of bacteria and insects as organisms that can evolve quickly due to short generations and large numbers of offspring.
3) An activity is described to show how bacterial resistance to antibiotics depends on genetic variation, the adaptive value of resistance genes, survival of resistant bacteria when exposed to antibiotics, and reproduction of the resistant bacteria to pass on those genes.
Pest and pesticides
The overuse of pesticides to control pests can have negative consequences like pest resurgence and secondary pest outbreaks as beneficial insects are killed. Pests also develop resistance over time requiring higher pesticide doses. Pesticide residues can also contaminate soil, water and crops, posing dangers to humans and animals. A more sustainable approach is biological control which uses natural predators and parasitoids to regulate pest populations and maintain ecological balance.

MICROBIOLOGY - INTRODUCTION.pptx
Microbiology is the study of microorganisms that are too small to be seen with the naked eye, including bacteria, fungi, and protozoa. These microbes play key roles in processes like soil formation, nutrient cycling, and were the only life forms on Earth for billions of years. There are several branches of microbiology focused on different types of microbes. Important figures like van Leeuwenhoek, Pasteur, Koch, and others helped develop microbiology and establish concepts like the germ theory of disease. Microbiology now informs diverse fields like medicine, biotechnology, and more.
Disease
This document discusses disease and its treatment. It defines disease as any condition that prevents effective functioning in an organism. Diseases are classified as either hereditary/congenital, meaning they are present at birth, or acquired, meaning they develop after birth. Acquired diseases include infectious diseases caused by living organisms, diet/deficiency diseases from too much or too little nutrients, cancers from uncontrolled cell growth, occupational diseases from work environments, and heart diseases from risk factors like smoking. The document also discusses infectious diseases in more depth, how they are spread, treated with antibiotics or prevented through immunization, and how the immune system and its defenses work to fight disease.
21 3 Ecology Of Fungi
Fungi play important ecological roles as decomposers and symbionts. Many fungi are saprobes that break down decaying matter for food. Others are parasites that live in and harm other organisms. Fungi also form beneficial symbiotic relationships, such as lichens with photosynthetic organisms and mycorrhizal relationships with plants. Fungi can also cause diseases in humans, plants and animals through the release of digestive enzymes and infection by microscopic spores.
BACTERIAS INFECTION AND IMMUNE SYSTEM RESPONSE
This document discusses bacteria and the human immune system response. It begins with an introduction comparing prokaryotic and eukaryotic cells, as well as pathogenic and non-pathogenic bacteria. It then discusses typhoid fever caused by Salmonella bacteria, noting how the immune system fights the infection through neutrophils and monocytes but some bacteria can still evade these responses. Next, it examines Group A Streptococcus and the toxins it produces that inhibit host cell protein synthesis. It is noted that increasing asparagine production is a host defense mechanism but also increases bacterial virulence, and that asparaginase may be a potential new treatment. Finally, it stresses the importance of continued research on bacterial virulence
Presentation for Antibiotic Resistance
Alexander Fleming discovered antibiotics in 1928 when he noticed that a mold growing in one of his culture plates was preventing the growth of Staphylococcus bacteria. Antibiotics either kill bacteria or prevent their growth, but overuse and misuse of antibiotics has led to many bacteria developing resistance. This includes methicillin-resistant Staphylococcus aureus (MRSA) which is now a major threat in hospitals. Antibiotic resistance occurs due to overuse of antibiotics for unnecessary infections, incomplete use of antibiotic regimens, and use of non-prescribed antibiotics. Proper antibiotic stewardship including only taking antibiotics as prescribed for the intended infection can help reduce the spread of resistance.
Good bad ecological
Bacteria can be categorized as good, bad, or ecological. The good bacteria maintain ecological equilibrium as producers, decomposers, and nitrogen fixers. They are also useful for food production, cleaning oil spills, and human digestion. However, bad bacteria cause disease and disrupt equilibrium. They damage cells by using them for food or releasing toxins. Controlling pathogenic bacteria requires resources. Ecological bacteria are important as decomposers, nitrogen fixers in food chains and symbiotic relationships, and many other living things could not survive without them.
AN EPISODE FROM THE ANTIBIOTIC ERA A TIME TO ACT
Bacteria have evolved to become resistant to antibiotics through misuse and overuse of antibiotics. Alexander Fleming discovered penicillin in 1929, beginning the antibiotic era and revolutionizing medicine by saving many lives. However, antibiotic resistance has increased in recent years as bacteria are no longer vulnerable to many drugs. The overprescription and misuse of antibiotics by doctors and patients has contributed to this growing problem. If antibiotic resistance continues to increase and no new antibiotics are developed, medicine could return to the pre-antibiotic era with many bacterial diseases being difficult or impossible to treat.

Importance and relevance of microbiology to nursing
Microbiology is the study of microscopic organisms and their interactions with other living systems. It is highly relevant to nursing as infectious diseases are a major health issue, especially with aging populations, and new diseases continue to emerge. Nurses must understand microbiology to properly control infections in hospitals, distinguish between harmful and harmless microbes, apply sterilization and cleanliness practices, and safely handle infectious patients and samples. Microbiology knowledge is essential for nurses to participate in healthcare activities like drug production, diagnosis, and treatment of disease.

Gene cloning
Gene cloning involves making many identical copies of a gene. It differs from cloning an entire organism. Gene cloning is done to isolate and study particular genes, identify control sequences and mutations, and engineer organisms for specific purposes like insulin production. It is accomplished by extracting DNA from an organism, cutting it into pieces with restriction enzymes, and inserting the gene of interest into bacterial plasmids which are then taken up by bacteria. This allows the gene to be amplified as the bacteria containing the recombinant plasmid multiply. PCR is another method that amplifies DNA fragments in vitro using heat-stable DNA polymerase and repeated heating and cooling cycles.

Antibiotics
Antibiotics have transformed medicine by providing treatments for bacterial infections that were previously untreatable. Before antibiotics, many deaths were caused by bacteria like Streptococcus pyogenes. Alexander Fleming's discovery of penicillin in 1928 led to the development of antibiotics that could kill bacteria. While antibiotics have saved many lives, their overuse and misuse has led to increased antibiotic resistance, which is now a major public health challenge. Proper antibiotic stewardship is needed to ensure these important drugs remain effective.

Antibiotic resistance has become a major public health issue as many bacterial infections are now resistant to common antibiotics. Overuse and misuse of antibiotics has led bacteria to evolve and become resistant. In hospitals, antibiotic use and underlying patient health conditions increase the risk of resistant infections. Community risks include close contact with infected individuals and antibiotic use in livestock. Homoeopathic approaches focus on remedies that address conditions from antibiotic overuse like Carbo Veg, Magnesium Phos, and Opium. Proper antibiotic use and hygiene are important for prevention.

School health awareness programme22
This presentation is made for school health awareness programme on antibiotic resistance. This includes introduction to antibiotics, antibiotic save lives, side effect of antibiotic, and detail about antibiotic resistance. This presentation is mostly focus on antibiotic resistance prevention.
POPH Antibotics
The overuse of antibiotics in both human medicine and agricultural practices has led to a growing problem of antibiotic resistance. When antibiotics are used to promote growth in farm animals, resistant bacteria can be passed to humans through meat consumption and spread among populations. If antibiotic resistance continues to increase, many infections could become untreatable, returning the world to a pre-antibiotic era. Reducing unnecessary antibiotic use in both medicine and agriculture is necessary to slow the development of resistance and preserve the effectiveness of these drugs.
Scope of microbiology
Microbiology is relevant to many areas of life. In agriculture, microorganisms play an important role in soil health and plant growth. They are involved in nutrient transformation and decomposition processes in the soil. In food microbiology, microbes are important for food production through fermentation, but can also contaminate foods and cause disease if proper safety practices are not followed. Pharmaceutical microbiology utilizes microbes to produce antibiotics, vaccines, and other drugs, while ensuring sterility during production. Astrobiology studies microbes in space as potential sources of oxygen, food, and waste processing for long term space missions.
The Pros And Cons Of Bacteria
The document discusses the pros and cons of bacteria, noting that while some bacteria can make us sick, bacteria also plays important roles in waste disposal, vaccines, and food production. While harmful bacteria like E. coli and Staphylococcus aureus can cause infections, the human body also relies on beneficial bacteria to maintain health. The document examines both the bacteria that should be avoided as well as the critical functions performed by other bacteria we depend on.
Antibiotics
Antibiotics are medications that destroy or slow down bacterial growth. Alexander Fleming discovered penicillin in 1928. While antibiotics have helped treat bacterial infections, their overuse and misuse has led to increasing antibiotic resistance in bacteria. This occurs as bacteria mutate and evolve in response to antibiotic use, becoming "superbugs" that are difficult or impossible to treat. Recent research focuses on developing new antibiotics and combination therapies to combat the growing threat of antibiotic resistance and ensure we continue to have effective treatments for bacterial infections.
final
The document discusses the role antibiotics play in disrupting the gut microbiome and the emergence of antibiotic-resistant bacteria. It outlines the early history of antibiotic discovery and current uses in agriculture and medicine. The overuse and misuse of antibiotics has put pressure on bacteria to develop resistance, undermining the effectiveness of our most powerful drugs. This has serious health implications, as at least 23,000 people in the US die each year from antibiotic-resistant bacterial infections. Both the medical and agricultural industries contribute to the problem through their antibiotic practices. Maintaining a diverse gut microbiome is important for health, but antibiotics can negatively impact this diversity.
Streptocci Research Paper
Through culture growth and effects on agar plates, Streptococci can be identified and differentiated. Alpha-hemolytic colonies from respiratory specimens are considered normal flora, while beta-hemolytic colonies are tested to identify the antigenic group as A or B. Identification can also be made by the ability of S. pyogenes to hydrolyze PYR, turning it bright red. Rapid immunoassay testing is also available to detect group A streptococci from throat swabs.
HOW MICROBES RULE THE WORLD?
Microbes outnumber human cells 10 to 1 and play important roles in human health and disease. While some microbes cause illness, most are harmless or beneficial. Microbes are found everywhere including in the air, water, soil, and inside and on the human body. They aid in digestion and prevent infection. However, overuse of antibiotics has led to increased antibiotic resistance in microbes, threatening our ability to treat infectious diseases. Antibiotic resistance occurs as bacteria evolve and share DNA allowing them to survive drug exposure. Prudent antibiotic use is needed to slow the development and spread of resistant microbes.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Antibiotics
- 3. Virtually all current antibiotics act only on replicating bacteria Antibiotics are generally active against multiplying bacteria, but are much less effective against non-replicating (latent) bacteria. Bacteria produce antibiotics Antibiotics are common metabolic product of bacteria (e.g. Streptomyces, Bacillus) and fungi. Bacteria produce antibiotics as their defense to kill
- 4. Antibiotics can't distinguish between the "good" and the "bad" bacteria There is a delicate balance of billions of bacteria inside our digestive tract. Bifido bacteria in the large intestine and acidophilus in the small intestine and vagina protect against infection by yeast and other bad bacteria. "Friendly" bacteria on the skin protect against bad bacteria, yeast, and fungal infections. Continued use of antibiotics, especially broad-spectrum antibiotics, can seriously disrupt the normal ecology of the
- 5. The worst thing one can do is to take only a few of the antibiotic prescribed At the beginning of treatment antibiotic wipes out the most vulnerable and weakest bacteria. Premature termination of antibiotic course will allow relatively resistant bacteria to survive and multiply. Proper dosage is very important for antibiotic effectiveness If the dosage of the antibiotic is not adequate, it will not be effective for treatment of the infection and bacteria are more likely to develop resistance. This is because the bacteria can

In the last 30 years the use of penicillin-type drugs in farm animals has increased by 600%, and of tetracycline by 1,500%. Antibiotics are largely used in raising pigs and
- 7. Antibiotics are life- savers Antibiotics have saved countless lives worldwide. When antibiotics were first used to treat bacterial infection they were hailed as the greatest lifesavers of all time. Before penicillin was discovered, infections were a leading cause of death. In 1900, the three leading causes of death were
