Abstract excerpt
The population structure of methicillin-resistant Staphylococcus aureus (MRSA) is predominantly clonal, which may be related to the fitness of the genetic background of the methicillin-susceptible S. aureus (MSSA) into which the mecA chromosomal resistant determinant has inserted. To test this idea, we assessed whether the genotypes of New York MRSA are present in MSSA populations by using a combination of...
