This feathery environmental sample is likely to be Bacillus mycoides, often recognized by its characteristic appearance. This particular bacterial specimen was propagated on GCB (gonococcal base) agar for several days at room temperature, with the plastic eyes added just prior to its disposal. Read More
This picture was taken in early October 2014 in the Washington, DC metro area. The temperature that week had been in the mid-70's during the day to the low 60's at night (Fahrenheit), and it hadn't been too humid. This had grown at the base of a tree, and was very large -- my hand is in there fo... 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

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
