Source NIH Scientists continue to uncover the many fascinating ways in which the trillions of microbes that inhabit the human body influence our health. Now comes yet another surprising discovery: a medicine-eating bacterium residing in the human gut that may affect how well someone responds to the most commonly prescribed drug for Parkinson’s disease. There
Elite athletes really are different from you and me. Or, at least their gut microbes are. Scientists who analyzed stool samples of 15 runners a week before and after they competed in the 2015 Boston Marathon found unusually high levels of one particular microbe compared to 10 non-athletes. Levels of the microbe in question, Veillonella,
The FDA is now aware of bacterial infections caused by multi-drug resistant organisms (MDROs) that have occurred due to transmission of a MDRO from use of investigational fecal microbiota for transplantation (FMT): Two immunocompromised adults who received investigational FMT developed invasive infections caused by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (E.coli). One of the individuals died. FMT
Results from three long-term studies following host and microbiome characteristics during pregnancy and preterm birth, inflammatory bowel disease, and prediabetes have expanded our understanding of how humans and microbes interact and the resulting consequences for our health. The studies were funded as part of a second phase of the National Institutes of Health’s Human Microbiome Project (HMP).
A number of physiological and psychological changes occur as we age, and many studies have shown that our gut microbiome also changes as we grow older. A fascinating new study is suggesting that a shift in gut bacteria in our middle-age could trigger a process that plays a role in cognitive decline in our later years. And
Highlights •Microbiome-derived NO promotes widespread S-nitrosylation of the host proteome •Interspecies S-nitrosylation regulates miRNAs, gene expression and host development •Microbiota control host function by shaping the post-translational landscape Summary Bioactive molecules can pass between microbiota and host to influence host cellular functions. However, general principles of interspecies communication have not been discovered. We show here
