mecC-MRSA in French Dairy Farms All mecC-positive strains belonged to the clonal complex CC130 and harbored the same spa-type t1736. Conclusion: This study found that mecC-positive MRSA isolates are able to persist within the same farms for several years after being introduced in this setting and are able to widely disseminate but only among dairy cows suggesting that milking machines might be a key player.
