 Community-acquired methicillin-resistant Staphylococcus aureus, CAMRSA, has become a global health concern due to its ability to spread rapidly in communities. This study examined the genetic makeup of 117 CAMRSA strains from different continents to determine, if there were any common genetic markers between them. The results showed that all of the strains had a similar genetic background, but they differed significantly depending on their geographical location. This suggests that the strains are likely to be spreading through local transmission rather than being imported from hospitals.
