Abstract:
Distribution of insertion sequence IS431 in clinical isolates of Staphylococcus aureus, Staphylococcus epidermidis, and Staphylococcus haemolyticus was investigated. Except for methicillin susceptible-S. aureus (MSSA), IS431 was detected in all isolates of the three staphylococcal species. In MSSA, only 20% of isolates with distinct coagulase types and genetic types possessed IS431. In a few MSSA isolates, an IS431 variant with internal deletion was found.
