Bacterium Causing U.S. Catfish Deaths Has Asian Roots

WASHINGTON, DC – June 3, 2014 – A bacterium causing an epidemic among catfish farms in the southeastern United States is closely related to organisms found in diseased grass carp in China, according to researchers at Auburn University in Alabama and three other institutions. The study, published this week in mBio®, the online open-access journal of the American Society for Microbiology, suggests that the virulent U.S. fish epidemic emerged from an Asian source.

Testing a Paleo Diet Hypothesis in the Test Tube

WASHINGTON, DC — May 20, 2014— By comparing how gut microbes from human vegetarians and grass-grazing baboons digest different diets, researchers have shown that ancestral human diets, so called paleo" diets, did not necessarily result in better appetite suppression. The study, published in mBio® the online open-access journal of the American Society for Microbiology, reveals surprising relationships between diet and the release of hormones that suppress eating.
