Multiple staphylococcal cassette chromosomes and allelic variants of cassette chromosome recombinases in Staphylococcus aureus and coagulase-negative staphylococci from Norway.

Abstract excerpt

We investigated the nature of the staphylococcal cassette chromosome mec (SCCmec) elements and cognate insertion sites in a collection of 42 clinical staphylococcal isolates of various species from Norway. The ccr and mec genes and the attachment sites (attL/attR) were identified by PCR, Southern blot hybridization, and DNA sequencing. We found 10 possibly new SCCmec types and one previously unreported variant of...
