Soil bacteria may provide clues to curbing antibiotic resistance

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.

Gut microbes in healthy kids carry antibiotic resistance genes

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.
