The routine use of antibiotics in agricultural animals are headed in the wrong direction: sales of antimicrobials important for human medicine have increased 20 percent since 2009 and 3 percent since 2012. Read More

Study of African birds reveals hotbed of malaria parasite diversity

A new study published last week in the journal PLOS ONE explores the scope of malaria parasite diversity in southeast African birds, and provides insight into how lifestyle characteristics of birds can influence their association with different parasite genera. Read More

Unprecedented microbial diversity reported in remote Amazonian tribe

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...

Iowa State, Ames Lab scientists describe protein pumps that enable bacteria to resist drugs

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

HOW MAPLE SYRUP COULD IMPROVE ANTIBIOTICS

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

Unearthing new antivirals

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

Paper and Phones Could Soon Diagnose Ebola and HIV for $1

Shape-shifting molecule tricks viruses into mutating themselves to death

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

How a bacterial cell recognizes its own DNA

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

Six questions about HIV/AIDS that deserve more attention

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...

To fight nasty digestive bugs, scientists set out to build a better gut -- using stem cells

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

HOW ZINC ‘JAMS UP’ THESE DRUG-RESISTANT MICROBES

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

YOUR GUT NEEDS BACTERIA TO MAKE MORE SEROTONIN

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
