The prevalence of arginine catabolic mobile element (ACME) among diverse and heterogeneous community‐associated methicillin‐resistant Staphylococcus aureus community‐associated Methicillin‐resistant S. aureus (CA‐MRSA) (n = 114)
in a low‐endemic area, i.e. Sweden, was investigated. Among the CA‐MRSA, represented by 47 different spa types, ACME was only found in 10 isolates with a common genetic background [t008, SCCmec type IV, Panton‐Valentine leukocidin (PVL) positive, and indistinguishable
or closely related pulsed‐field gel electrophoresis (PFGE)‐patterns] corresponding to USA300. This strain does not seem to be established in our area as most of the patients contracted the CA‐MRSA abroad. Presence of ACME does not seem to be associated with colonization,
long‐term carriership, or intra‐familiar transmission in a higher extent than CA‐MRSA in general.
