Researchers are working on a vaccine that might one day prevent norovirus, which has made many cruise ship passengers in the United States ill.
"It is possible to prevent infection and illness with a vaccine for norovirus," said Dr. Robert Atmar, a professor of medicine and molecular virolo... Read More

The winning photography entry, "Glass Forest," depicts at the microscale level a community of diatoms, unicellular algae characterized by a peculiar glass-like cell wall, att... Read More
Snottites have captivated cave-goers and scientists alike since the earliest publication on cave microbes by Hoeg in 1946. These biofilms cover the walls with a thick snot-like film, from which they derive their particularly appropriate name. A variety of cave systems, the Frasassi caves in Ital... Read More
Scientists have managed to reverse type 1 diabetes (T1D) in experimental mice by giving the animals an oral course of harmless gut bacteria that had been engineered to secrete the whole proinsulin autoantigen (PINS) and the immunomodulatory human cytokine IL-10 (hIL10). An international team led... Read More

A recent test of packaged raw chicken products bought at grocery stores across the country found that roughly half of them were contaminated with the bacteria E. coli.
E. coli, which the study said was an indicator of fecal contamination, was found in 48 percent of 120 chicken products bought... Read More
Researchers have determined that bacteria are present in the bladders of some healthy women, which discredits the common belief that normal urine is sterile. These findings were published in the April issue of the Journal of Clinical Microbiology by researchers at Loyola University Chicago Strit... Read More

A bacteria strain that causes a hard-to-treat staph infection probably developed its antibiotic resistance in food animals, a team of scientists announced Tuesday.
The strain of staph, known as methicillin-resistant Staphylococcus aureus, or MRSA CC398, most often infects farm workers who com... Read More
Two papers published this week, and one last month, reveal the pandemic potential of H5N1 "bird flu". One identifies four, another identifies five, genetic changes the virus would have to undergo before it could spread easily in humans, and the third paper suggests some of these changes are alre...

One in every six cancers worldwide is caused by an infection that is preventable or treatable, according to new estimates published in the journal Lancet Oncology. The research indicates infections are attributable for approximately 2 million new cancer cases every year.
"Infections with cert... Read More
Bacteria can multiply rapidly, potentially doubling every 20 minutes in ideal conditions but this exponential growth phase is preceded by a period known as lag phase, where no increase in cell number is seen. Lag phase was first described in the 19th Century, and was assumed to be needed by bact... Read More
If you've ever had a bacterial infection like staph or strep throat, your doctor may have prescribed penicillin. But if you've had the flu or a common cold virus, penicillin won't work. That's because antibacterials only kill bacteria, and both the flu and the common cold are viruses. So for ill... Read More
