Molecular typing of methicillin-susceptible Staphylococcus aureus isolates collected in the Yogyakarta area in Indonesia, 2006

The characterization of 62 community-associated methicillin-sensitive Staphylococcus aureus (MSSA) isolates from 440 individuals in the Yogyakarta area of Indonesia in 2006 showed that: (i) almost half of the isolates were associated with methicillin-resistant S. aureus lineages [clonal complex (CC)1, CC8 and CC45] and (ii) ten Panton–Valentine leukocidin-positive isolates were associated with CC1 (n = 7), CC30 (n = 1) and CC51 (n = 2). The high Panton–Valentine leukocidin prevalence (16%) among S. aureus is of concern because these strains can cause severe infections and the introduction of staphylococcal cassette chromosome mec into virulent and epidemic MSSA could pose a serious public health threat.
