EurekAlert -- Researchers from Iowa State University have identified a novel factor that promotes the development of antibiotic resistance in a bacterial pathogen. The study, published June 6th in the open-access journal PLoS Pathogens, explains that Mfd, a protein involved in DNA transcription and repair, plays an important role in the development of fluoroquinolone resistance in Campylobacter, a bacterial pathogen commonly associated with food poisoning in humans.
