Typing of staphylococcal cassette chromosome mec encoding methicillin resistance in Staphylococcus aureus strains isolated at the bone marrow transplant centre of Tunisia.

Abstract excerpt

Staphylococcal Cassette Chromosome mec (SCCmec) is a mobile genetic element that carries the gene mecA mediating the methicillin resistance in staphylococci. It is composed of mec and ccr gene complexes. Six SCCmec types have been defined so far. SCCmec typing of 13 methicillin-resistant Staphylococcus aureus (MRSA) out of 72 (18%) non redundant S. aureus strains recovered in 1998-2007 at the Bone Marrow...
