Whole genome sequencing confirms livestock-to-human MRSA transmission

A study published in the journal EMBO Molecular Medicine confirmed that human infections in Denmark were caused by a type of methicillin-resistant Staphylococcus aureus (MRSA) found in livestock. Research was conducted in the UK and Denmark on two Danish subjects who lived on farms. The blood and nasal passage of one was positive for mecC-MRSA and the other had a wound infected with mecC-MRSA. Samples from the patients differed by only a handful of single nucleotide polymorphisms from those of a cow and two sheeps that lived on the farms. The similarity suggests transmission, but researchers remain unsure of which direction the transmission occurred. Read the study here.
