Streptococcus pneumoniae is a major human pathogen and is known to be associated with increased risk of fatal heart complications including heart failure and heart attacks. Read More
It's no wonder that giant pandas are always chewing and eating, say Chinese researchers: their gut bacteria are not the type for efficiently digesting bamboo. Read More
A seven-year scientific study has revealed that microbial communities in urban waterways have the potential to play an important role in cleansing Singapore's waterways and also act as raw water quality indicators. Read More
A new study delineates a sequential pattern of changes in the intestinal microbial population of patients recovering from cholera in Bangladesh, findings that may point to ways of speeding recovery from the dangerous diarrheal disease. The report also finds what appear to be consistent differenc... Read More
A team led by researchers from UC San Francisco, Organic Health Response, and Microclinic International is reporting results of a study that showed significant benefits of microclinics -- an innovative intervention that mobilized rural Kenyan HIV patients' informal social networks to support the...

(Millbrook, NY) Machine learning can pinpoint rodent species that harbor diseases and geographic hotspots vulnerable to new parasites and pathogens. So reports a new study in the Proceedings of the National Academy of Sciences led by Barbara A. Han, a disease ecologist at the Cary Institute of E... Read More
A new study led by researchers at the University of Minnesota has found a three-way link among antibiotic use in infants, changes in the gut bacteria, and disease later in life. The imbalances in gut microbes, called dysbiosis, have been tied to infectious diseases, allergies and other autoimmun... Read More
The decision to warn the world of future global disease epidemics like Ebola would be taken out of the hands of the director general of the World Health Organisation under plans formulated by experts at a meeting hosted by Angela Merkel, the German chancellor. Instead it would be given to a new ... Read More
Investigators found that nearly half of the 50 chicken meat samples purchased from supermarkets, street markets, and butchers in Austria contained viruses that are capable of transferring antibiotic resistance genes from one bacterium to another—or from one species to another. “Our work suggest...

Niger’s Ministry of Public Health notified WHO of 5,855 suspected cases of meningococcal meningitis, including 406 deaths. This is a rapidly growing outbreak with some unprecedented features.
Suspected cases have been increasing very quickly, tripling over the last 2 weeks (see previous notif... Read More
BioSentinel--it sounds like Hollywood’s next big sci-fi film. Rather, it's one of NASA’s upcoming missions, with the goal of studying the long-term effects of radiation on human cells. The mission, run by scientist’s at NASA’s Ames Research Center, will be the first biological experiment to take... Read More
A dangerous type of bacteria can not only block their own growth, but also the growth of their antibiotic-resistant mutants.
The discovery might lead to better ways to fight bacteria that are becoming increasingly resistant to antibiotic treatments.
“This means we can start to think about ... Read More

Vincent, Dickson, and Daniel reveal last week's case study and introduce a new one concerning a patient who traveled to Belize.
Researchers have discovered the structure of a key protein on the surface of an unusually large virus called the mimivirus, aiding efforts to determine its hosts and unknown functions.
The mimivirus was initially thought to be a bacterium because it is much larger than most viruses. It was is... Read More
Over the past few years, researchers have gotten a much better idea of the importance of the human microbiome--the trillions of bacteria living in and around our bodies. Now we know that these bacteria can make us more obese, change how our brains work, and are unique to individuals. Although a ... Read More
Nebraska Governor Pete Ricketts declared a state of emergency on Thursday, after federal agriculture officials confirmed a second farm site had tested positive for the rapidly spreading avian flu virus.
The declaration follows earlier, similar actions by governors in Wisconsin, Minnesota and ... Read More
