Two herdsmen in the country of Georgia have been infected with a brand-new virus, scientists from the Centers for Disease Control and Prevention said Thursday. The newly identified virus is a second cousin to smallpox. And, like smallpox, it causes painful blisters on the hands and arms. Other ... Read More
The nucleoside adenosine—a tiny chemical structure made up of a simple base linked to a sugar—is critical for the regulation of bodily functions ranging from blood flow to tissue repair to sleep. Now, researchers at Rutgers New Jersey Medical School show that adenosine is essential in promoti... Read More
Scientists from the University of Bern have developed a novel substance for the treatment of severe bacterial infections without antibiotics, which would prevent the development of antibiotic resistance.
Ever since the development of penicillin almost 90 years ago, antibiotics have remained t... Read More
Exciting research suggests that a shot every one to three months may someday give an alternative to the daily pills that some people take now to cut their risk of getting HIV. The experimental drug has only been tested for prevention in monkeys, but it completely protected them from infection in... Read More

Vincent, Alan, Rich and Kathy discuss how interleukin 10 modulation of Th17 helper cells contributes to alphavirus pathogenesis.
Virulence, the capacity to cause disease, varies markedly among viruses. Some viruses cause lethal disease while others do not. For example, nearly all humans infected with rabies virus develop a disease of the central nervous system which ultimately leads to death. In contrast, most humans are ... Read More
A healthy and balanced diet, as well as probiotics, have been known to be helpful in preserving gastrointestinal health for quite a long time. But it is only recently that the underlying mechanisms have become somewhat clearer. A rapidly increasing body of knowledge promises to further clarify t... Read More
I came across this paper and thought it sounded interesting for a discussion on TWiP:
Colonisation resistance in the sand fly gut: Leishmania protects Lutzomyia longipalpis from bacterial infection
A chemist at Washington University in St. Louis is studying siderophores, iron chelating molecules released by bacteria during an infection, with the thought of using them to design personalized antibiotic therapy that would avoid the rapid evolution of resistance that plagues antibiotic drug di...

Researchers from the National Collection of Yeast Cultures (NCYC) at the Institute of Food Research (IFR) have identified a new globe-trotting yeast species that lives on tree-associated beetles. This new species demonstrates the importance of preserving biodiversity, as yeasts like this may hel... Read More
Like animals, plants are susceptible to infections from bacteria, viruses and fungi. While animals have a wide variety of immune cells and in some cases an interconnected immune system plants must rely on other methods to fight infection. A recent news bulletin from the Howard Hughes Medical Ins... Read More
Eighty-six years after the discovery of penicillin, docs are running out of antibiotics to treat serious infections like Clostridium difficile and gonorrhea, according to the Centers for Disease Control and Prevention. At the same time, the discovery of new "wonder drugs" has slowed, and microbi... Read More
(CNN) -- Evidence is mounting against camels as leading suspects in a deadly mystery that's claimed more than 100 lives in the Middle East. The biological supervillain is the virus causing MERS-coV, short for Middle East Respiratory Syndrome, a type of coronavirus. Since the first documented cas... Read More
The arrival in the United States of a Liberian man infected with the Ebola virus shows how easily the disease can travel and how thin the procedures are, relying heavily on the honesty of travelers and the diligence of airport workers. Some experts say that the system, given its inherent weaknes... Read More
Scientists from The University of Manchester have discovered that 'lonely' microbes are more likely to mutate, resulting in higher rates of antibiotic resistance.
The study, published today in Nature Communications and jointly funded by The Wellcome Trust and Engineering and Physical Sciences... Read More
Bacteria found in the nose may be a key indicator for future development of skin and soft-tissue infections in remote areas of the body, researchers say. The nose is the primary S. aureus reservoir in humans and nearly 80% of the time, an individual's colonizing strain is the same strain that ca... Read More
Q. When you eat yogurt or take a probiotic supplement, why aren’t the probiotic bacteria killed by stomach acids?
A. The point of consuming a probiotic supplement in a food like yogurt, a powder or a capsule is to introduce beneficial bacteria in the gut, said Dr. Christine Frissora, a gastro... Read More
Conjugal plasmids provide microbes with full complements of new genes. Conjugal plasmid transfer is deemed responsible for the rapid spread of antibiotic resistance among microbes. While broad host range plasmids are known to confer transfer abilities to diverse hosts in pure culture, the extent... Read More
