Research opens possibility of reducing risk of gut bacterial infections with next-generation probiotic

A team of researchers is exploring the possibility that next-generation probiotics – live bacteria that are good for your health – would reduce the risk of infection with the bacterium Clostridium difficile. In laboratory-grown bacterial communities, the researchers determined that, when supplied with glycerol, the probiotic Lactobacillus reuteri produced reuterin, an antibacterial compound that selectively […]

Flesh-Eating Infections In Rheumatoid Arthritis Patients Spur New Discovery

Rheumatoid arthritis patients taking medications that inhibit interleukin-1beta (IL-1beta), a molecule that stimulates the immune system, are 300 times more likely to experience invasive Group A Streptococcal infections than patients not on the drug, according to University of California San Diego School of Medicine researchers. Their study, published August 19 in Science Immunology, also uncovers […]
