Abstract
Reports of methicillin-resistant Staphylococcus aureus (MRSA) harboring the mecC gene have increased in the UK since first being described. To our diagnostic S. aureus multiplex PCR, a mecC primer set was designed and implemented, and then the prevalence in our patient population was investigated. Fewer than 1% of the clinical isolates possessed the mecC gene, confirming that mecA remains the dominant genetic determinant of MRSA in East London.
