Research published today in PLOS Pathogens reveals how viruses called bacteriophages destroy the bacterium Clostridium difficile (C. diff), which is becoming a serious problem in hospitals and healthcare institutes, due to its resistance to antibiotics. The study, by scientists at the European Molecular Biology Laboratory (EMBL) in Hamburg, Germany, could help bring about a new way of fighting this and other bacteria.
"Our findings will help us to engineer effective, specific bacteriophages, not just for C. diff infections, but for a wide range of bacteria related to human health, agriculture and the food industry," says Rob Meijers from EMBL, who fac lzn cwoz.
