Abstract

In a collection of 50 pvl-positive Staphylococcus aureus isolates from 10 Rio de Janeiro hospitals, 18 (36%) were from bloodstream infections, and 31 (62%) carried the SCCmec IV. Among 25 (50%) isolates of the USA1100/ST30/CC30 lineage present in 8 hospitals, 1 isolate was characterized as vancomycin-intermediate S. aureus.

Keywords: Panton-Valentine leukocidin; Staphylococcus aureus; USA1100/ST30/CC30; Vancomycin-intermediate S. aureus.
