Researchers at the University of Bern have identified a new antibiotic resistance gene in Macrococcus caseolyticus strains from dairy cows. This gene confers resistance to all beta-lactam antibiotics including the last generation of cephalosporins used against methicillin-resistant Staphylococcus aureus (MRSA). A transfer to S. aureus (which is possible according to the researchers) would jeopardize the […]
