Diet matters less than evolutionary relationships in shaping gut microbiome

Gut microbes provide many services for their hosts, including digesting their food. Researchers have long known that mammals with specialized diets, such as carnivores and anteaters, have special types of gut microbes that allow them to eat that diet. Is the same true in primates? In the largest published comparative dataset of non-human primate gut microbiomes to date, a new ...

Insights from metabolites get us closer to a test for chronic fatigue syndrome

A study led by researchers at the Center for Infection and Immunity (CII) at Columbia University’s Mailman School of Public Health has identified a constellation of metabolites related to myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Combining this data with data from an earlier microbiome study, the researchers now report they can predict whether or not someone has the disorder with a ...

Gut bacteria byproduct protects against Salmonella

Researchers at the Stanford University School of Medicine have identified a molecule that serves as natural protection against one of the most common intestinal pathogens. Propionate, a byproduct of metabolism by a group of bacteria called the Bacteroides, inhibits the growth of Salmonella in the intestinal tract of mice, according to the researchers. The finding may help to explain why ...

Researchers turn powerful, viscous disinfectants into breathable mist for the first time

A team of engineers and physicians in San Diego have developed a device that diffuses potent disinfectants for airborne delivery. Notably, the device works on a range of disinfectants that have never been atomized before, such as Triethylene glycol, or TEG. In a study published in the August issue of Applied Microbiology and Biotechnology, the team used the device to ...

Novel PET imaging noninvasively pinpoints colitis inflammation sites

A novel positron emission tomography (PET) imaging method shows promise for noninvasively pinpointing sites of inflammation in people with inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn’s disease. The University of California, Los Angeles (UCLA), study is featured inThe Journal of Nuclear Medicine. The U.S. Centers for Disease Control states that approximately three million Americans reported being diagnosed ...
