Is it possible that our personal hygiene routines make us too clean? Are we soaping and cleansing away friendly microbes that help preserve skin health? A study presented at the 5th American Society for Microbiology Conference on Beneficial Microbes in Washington, DC, provides food for thought o... Read More
Some people infected with pathogens spread their germs to others while remaining symptom-free themselves. Now, investigators at the Stanford University School of Medicine believe they may know why.
When the scientists gave oral antibiotics to mice infected with Salmonella typhimurium, a bacte... Read More
The polio eradication and endgame strategic plan announced by the World Health Organization in 2014 includes at least one dose of inactivated poliovirus vaccine (IPV). Since 1988, when WHO announced the polio eradication plan, it had relied exclusively on the use of oral poliovirus vaccine (OPV)... Read More
Bovine viral diarrhea virus infections result in one of the most costly diseases among cattle with losses in U.S. herds estimated at $2 billion per year, according to professor Christopher Chase of the South Dakota State University Veterinary and Biomedical Sciences Department.

Oxytricha trifallax lives in ponds all over the world. Under an electron microscope it looks like a football adorned with tassels. The tiny fringes are the cilia it uses to move around and gobble up algae. What makes Oxytricha unusual, however, is the crazy things it does with its DNA.
Unlike... Read More

Up to 1 in 25 patients with hospital-acquired infections. It may be that standard hand-washing and sterilization procedures in hospitals aren't enough, which is where these new fabrics that can kill bacteria come in.
University researchers in Australia have shown how cotton fabrics impregnate... Read More
Scientists looking for Ebola in bats have identified 16 other viruses in the animal which could jump to humans and potentially cause a disease outbreak on a similar scale to the West African crisis, a health security expert said on Friday.
Humans can contract Ebola from bats, which are carrie... Read More

As the world experiences a wakeup call about the rise of drug-resistant infections, a new approach to creating smarter, “programmable” drugs could combat the two major problems with life-saving drugs today.
On the one hand, today’s antibiotics work a little too well. They not only kill infect... Read More
A parasitic fungus that must kill its ant hosts outside their nest to reproduce and transmit its infection, manipulates its victims to die in the vicinity of the colony, ensuring a constant supply of potential new hosts, according to researchers at Penn State and colleagues at Brazil's Federal U...

Treating dairy cows and other farm animals with antibiotics and then laying their manure in soil can cause the bacteria in the dirt to grow resistant to the drugs. But a study now suggests that the manure itself could be contributing to resistance, even when it comes from cows that are free of a... 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
Last week two American aid workers who had contracted Ebola while working in west Africa were released from a U.S. hospital and pronounced “recovered.” They had been flown to Emory University Hospital in Atlanta from Liberia earlier this month to receive care in the hospital’s specialized infect...

Swarming, white growth with finger like projections at the outer edges, around the circular solated colonies, circular white/beige opaque colonies, was not seen until ... Read More
Contrary to popular belief, the foodborne pathogen Campylobacter jejuni is not a harmless commensal in chickens but can cause disease in some breeds of poultry according to research. Campylobacter jejuni is the most frequent cause of foodborne bacterial gastroenteritis in the world and the Cente... Read More
