Bacteria that naturally live in the soil have a vast collection of genes to fight off antibiotics, but they are much less likely to share these genes than infectious bacteria, a new study by researchers at the School of Medicine has revealed. Shown is senior author Gautam Dantas, PhD.
Friendly microbes in the intestinal tracts of healthy American children have numerous antibiotic resistance genes, according to results of a pilot study by scientists at the School of Medicine. The genes are cause for concern because they can be shared with harmful microbes, interfering with the effectiveness of antibiotics in ways that can contribute to serious illness and, in some cases, death. Pictured is the study’s senior author, Gautum Dantas, PhD.
Our bodies contain far more microbial genes than human genes. And a new study suggests that just as human DNA varies from person to person, so too does the massive collection of microbial DNA in the intestine.
A largely unexplored world of viruses make their home in the lower intestine, and new research at Washington University School of Medicine in St. Louis suggests that each of us harbors a unique collection of these “friendly” viruses. The research is published in the journal Nature.
As part of the Human Microbiome Project (HMP), scientists at Washington University School of Medicine in St. Louis and their colleagues have decoded the genomes of 178 microbes from the human body, they report in the journal Science.
