What will the next big zoonotic virus be? Most emerging infectious diseases are zoonoses, and many, if not most, of them are caused by viruses, but right now we have little idea what viruses are out there in livestock and wildlife, let alone which one might be next in line to cause a human pande...

The Ministry of Health, Labor and Welfare announced on Monday that it will pursue the production of vaccine against the H7N9 avian flu virus that is still spreading across China. The ministry aims to develop the vaccine as soon as possible before the virus mutates and imposes further risk to hum... Read More
Flu vaccination is no longer merely a choice between a jab in the arm or a squirt in the nose. This fall, some brands promise a little extra protection.
For the first time, certain vaccines will guard against four strains of flu rather than the usual three. Called quadrivalent vaccines, these... Read More
Scientists have found another chink in bacteria's armour, mapping for the first time the structure of a protein that plays an important role helping infection gain a foothold in the body.
Published today in Nature a group of international scientists from Monash University, the National Instit... Read More
Tuberculosis is an ancient disease that still affects millions of people, largely in developing countries. A startling statistic valued by fundraisers for tuberculosis research is that this devastating disease claims three lives every minute worldwide. Since a major factor underlying this import...

Over the many years that I taught microbiology to medical students, perhaps my least favorite lecture was the one on the “normal flora,” what we now call the microbiome. What used to make me grumpy was that I could talk only in vague generalities, rambling about the intestinal flora being an imm... Read More
Bacteria living in the Gulf of Mexico beaches were able to 'eat up' the contamination from the Deep Water Horizon oil spill by supplementing their diet with nitrogen, delegates at the Goldschmidt conference will be told today, Friday 30th August.
Professor Joel Kostka will tell geochemists ga... Read More
Researchers have devised a way to turn the tables on a sneaky strain of bacteria that can cause life-threatening diseases, based on a technique using infrared light.
Scientists at the University of Veterinary Medicine, Vienna said the technique lets them differentiate strains that can cause ... Read More
If the idea of hookworms makes you shudder, consider this: Those pesky intestinal parasites may actually help your body ward off other infections, and perhaps even prevent autoimmune and other diseases.
Studying members of the Tsimane, an indigenous population in the lowlands of Central Boliv... Read More
Left untreated, a serious tooth abscess can eventually kill.
In 2007, Deamonte Driver, a 12-year-old boy in Maryland, died after bacteria from an abscessed tooth spread to his brain. The case drew widespread media attention, and his is the cautionary tale cited whenever politicians and advoca... Read More
This episode: A strain of E. coli helps reduce severity of Salmonella infection by competing with it for iron in the gut!
Scientists say that around a quarter of the population, particularly those who are obese, have 40% less intestinal bacteria than needed to maintain good health, according to a study published in the journal Nature.
Researchers from Europe conducted a genetic analysis on human gut microbial co... Read More
A diverse range of life forms exists deep below Earth's surface, scientists have concluded, but they survive at an incredibly slow pace.
Long-lived bacteria, reproducing only once every 10,000 years, have been found in rocks 2.5km (1.5 miles) below the ocean floor that are as much as 100 mill... Read More
Everywhere you go, the trillions of microbes in your gut go too. And that's a comforting thought. Because according to a new study, a more diverse population of intestinal bacteria is linked to better health. The work is in the journal Nature. [Emmanuelle Le Chatelier et al, Richness of human gu... Read More
People who have less diversity in their intestinal microbiomes tend to be heavier and have more inflammation and metabolic dysfunction than those who have a more robust portfolio of gut bacteria, researchers found.
In an analysis of data from the European consortium MetaHIT, about a quarter o... Read More
What types of microbes do mothers transmit to their newborns and how universal is maternal microbial transmission throughout animals, including from your mother?
The sterile womb paradigm is an enduring premise in biology that human infants are born sterile. Recent studies suggest that infant... Read More
Based on a Twitter conversation with two microbiology educators, I share a story of how (through a survey) I encourage students to look deeply at their study strategies and promote "ownership" in their classroom experience. Read More
Researchers from the Perelman School of Medicine at the University of Pennsylvania demonstrate for the first time that the immune system influences the skin microbiome. A new study found that the skin microbiome -- a collection of microorganisms inhabiting the human body -- is governed, at least... Read More
