Using whole genome sequencing, scientists have found conclusive evidence that a type of methicillin-resistant Staphylococcus aureus (MRSA) that caused human infections in Denmark came from livestock – adding to concerns that food animals are a significant MRSA reservoir for human infections.
While previous research has suggested that MRSA transfers from animals to humans, including a U.S. study last year that looked at “pig-MRSA,” the study published this week in EMBO Molecular Medicine provides the strongest evidence to date that this phenomenon is occurring and provides fodder to those advocating for greater limits on antibiotics in agriculture.
