SCCmec

SCCmec, or Staphylococcal Cassette Chromosome mec, is a mobile genetic element that carries the methicillin resistance gene (mecA) in Staphylococcus aureus, particularly in methicillin-resistant Staphylococcus aureus (MRSA). This genetic element is crucial for understanding the mechanisms of antibiotic resistance in staphylococcal infections.
