April 17, 2015 - A multicenter team of U.S. and Venezuelan scientists, led by researchers from NYU Langone Medical Center, have discovered the most diverse collection of bodily bacteria yet in humans among an isolated tribe of Yanomami Indians in the remote Amazonian jungles of southern Venezuel...

Research teams led by Edward Yu of Iowa State University and the Ames Laboratory have described the structures of two proteins they believe pump antibiotics from bacteria, allowing the bacteria to resist medications.
One of the protein pumps, known as MtrF, is believed to be the mechanism tha... Read More
The Centers for Disease Control and Prevention revised its guidelines on Ebola transmission on Sunday night, urging survivors to abstain from all forms of sex or use condoms every time “until more information becomes available,” rather than three months as previously recommended.

A concentrated extract of maple syrup makes disease-causing bacteria more susceptible to antibiotics, according to laboratory experiments.
The findings, which will appear in the journal Applied and Environmental Microbiology, suggest that combining maple syrup extract with common antibiotics ... Read More
SAN DIEGO (April 14, 2015) -- A team of biologists from San Diego State University has developed a platform for identifying drugs that could prove to be effective against a variety of viral diseases. In a pair of recent articles in the Journal of Biomolecular Screening and the Journal of Visuali... Read More
Diseases such as HIV and Ebola are on the verge of being diagnosed almost instantly using paper-based technology costing less than $1. Read More
A newly developed spectroscopy method is helping to clarify the poorly understood molecular process by which an anti-HIV drug induces lethal mutations in the virus's genetic material. The findings from the University of Chicago and the Massachusetts Institute of Technology could bolster efforts ... Read More
It may come as a bit of a surprise to learn that bacteria have an immune system - in their case to fight off invasive viruses called phages. And like any immune system - from single-celled to human - the first challenge of the bacterial immune system is to detect the difference between "foreign"... Read More
As HIV investigators work to control and eradicate the virus worldwide, certain myths or misconceptions about the disease have been embraced, whereas other concepts with merit have been left relatively unexplored, argues American HIV/AIDS researcher Jay Levy, MD, in a commentary publishing April...

Researchers at the University of Michigan are studying the ecology of microbes in the GI tract in hopes of developing novel diagnostic tests and effective treatments for intestinal disease. How are they studying this? By creating tiny gut ecosystems! Using undifferentiated stem cells, the inv... Read More
An Ebola vaccine candidate that has been successful in non-human primates is being tested on volunteers in Sierra Leone this month, where two new cases were reported as of Monday. Read More
New research from the University of Queensland has shown how zinc "tricks" an essentialmManganese-transport protein of S. pneumoniae into a shape in which it can't accept manganese. It is known that manganese is essential for S. pneumoniae infection to occur, so this research offers a chance to... Read More
A new study from CalTech suggests that serotonin levels may be regulated to some degree by the gut microbiome. Researchers are investigating the degree to which bacteria in the guts of mice are able to confer serotonin-dependent function in comparison to control, or "germ-free" mice. Further s... Read More
Science writer Maryn McKenna interviews John Sever, MD, PhD, former chief of infectious diseases at the National Institutes of Health and current vice-chairman of Rotary’s International PolioPlus Committee, about the early days of the polio struggle and the introduction of the polio vaccine.

A leukemia-like cancer is killing soft-shell clams along the east coast of North America. The cancer is transmitted between animals in the ocean, and appears to have originated in a single clam as recently as 40 years ago. Read More
Human norovirus may infect our canine companions, according to research published online April 1 in the Journal of Clinical Microbiology, a publication of the American Society for Microbiology. That raises the possibility of dog-to-human transmission, said first author Sarah Caddy, VetMB, PhD, M... Read More
