A team of investigators has discovered a new, more powerful variant on an antimicrobial resistance gene common among Staphylococcus species. The gene protects the bacteria from an antiseptic compound widely used in healthcare. The team showed that the newly discovered gene occurs in a highly virulent and multi-resistant clone of Staphylococcus epidermidis, found in healthcare settings worldwide.
Researchers from the San Diego Zoo Global Institute for Conservation Research have found the gut microbiota of the captive southern white rhinoceros may partially explain its infertility.
A team of investigators has identified a cluster of four patients harboring Escherichia coli carrying a rare antibiotic resistance gene, mcr-1. That gene renders the microbe resistant to colistin, an antibiotic of last resort against some multidrug-resistant infections. Three of those patients showed no symptoms, raising the risk of spread.
Intestinal infection with helminths—a class of worm-like parasites—prevented weight gain in laboratory mice on a high-fat diet. The helminths did so by boosting populations of bacteria that produce compounds that trigger increased energy consumption in the mice.
