The social amoeba Dictyostelium discoideum can farm symbiotic bacteria for food by carrying them from generation to generation. New research shows that these bacteria can also protect the amoeba from environmental toxins.
Bacteria aren’t the only non-human invaders to colonize the gut shortly after a baby’s birth. Viruses also set up house there, according to new research led by Lori Holtz, MD, at Washington University School of Medicine in St. Louis.
Infections with one of the most troublesome and least understood antibiotic-resistant “superbugs” are increasing at alarming rates, particularly in health-care settings. But by studying A. baumannii, a frequent cause of difficult-to-treat infections in hospitals, researchers have identified a naturally occurring process that restores its vulnerability to antibiotics.
The acidity of urine — as well as the presence of small molecules related to diet — may influence how well bacteria can grow in the urinary tract, a new study shows. The research, led by Jeffrey Henderson, MD, PhD, at Washington University School of Medicine in St. Louis, may have implications for treating urinary tract infections, which are among the most common bacterial infections worldwide.
A newly discovered link between bacteria and immune cells sheds light on inflammatory bowel disease, an autoimmune condition that affects 1.6 million people in the United States, according to researchers at Washington University School of Medicine in St. Louis.
Antibiotic resistance is poised to spread rapidly around the globe among bacteria frequently implicated in respiratory and urinary infections in hospital settings, according to new research at the School of Medicine.
Antibiotics aren’t supposed to be effective against viruses, but new evidence in mice suggests they may help fight norovirus, a highly contagious virus that causes severe gastrointestinal illness, scientists at the School of Medicine report.
The most common type of hospital-associated infection may be preventable with a vaccine, new research in mice suggests. The experimental vaccine, created by School of Medicine researchers, prevented urinary tract infections associated with catheters, the tubes that hospitals and other care facilities insert to drain urine from the bladder.
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.
A multi-institutional campaign to harness a newly recognized cellular defense against infection is being led by researchers at the School of Medicine. A $32 million grant from the National Institutes of Health is funding the collaborative, which could lead to drugs with unprecedented versatility in fighting different infections. Washington University’s Herbert W. Virgin IV, MD, PhD, is the principal investigator.
