Use of Coagulase Gene (coa) Repeat Region Nucleotide Sequences for Typing of Methicillin-Resistant Staphylococcus aureus Strains

ABSTRACT

Coagulase gene (coa) short sequence repeat region sequencing was used to measure relatedness among a collection of temporally and geographically diverse methicillin-resistantStaphylococcus aureus isolates. The results show thatcoa polymorphism is free of strong selective pressure and has a low index of variation that may be useful for long-term epidemiological investigations. coa typing is a useful addition to spa typing for analysis of S. aureus, including methicillin-resistant strains.
