چکیده
Epidemiological surveillance for community-associated methicillin-resistant Staphylococcus aureus revealed prevalences of 33% and 13% in pediatric and adult patients, respectively, in Cordoba, Argentina, in 2005. This study describes for the first time the emergence and dissemination of the sequence type 5 (ST5) lineage as the most prevalent clone (89%) (pulsed-field gel electrophoresis type I-ST5-staphylococcal cassette chromosome type IVa-spa type 311) harboring the Panton-Valentine leukocidin and enterotoxin A genes.

Emergence of an epidemic clone of community-associated methicillin-resistant panton-valentine leucocidin-negative Staphylococcus aureus in cystic fibrosis patient populations.
The article by Moroney et al. (3) documents the increased prevalence of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) strains in different patient populations. Most of the CA-MRSA strains characterized by carriage of staphylococcal cassette chromosome mec (SCCmec) type IV were also positive for the Panton-Valentine leucocidin (PVL) gene 1 (2). However, this gene ass...

OBJECTIVES The aim of this paper is to attribute Panton-Valentine leucocidin (PVL)-positive methicillin-resistant Staphylococcus aureus (MRSA) to clonal lineages by molecular typing with special reference to isolates exhibiting spa type t008/multilocus sequence type (MLST) ST8 [widely disseminated in the USA as 'community-associated MRSA (caMRSA) USA300']. METHODS PVL-positive MRSA (n = 117) ...

This study aimed to determine the antibiotic susceptibility pattern of Staphylococcus aureus (SA) and the circulating clones in Bangalore, India. Susceptibility testing was performed for all cases of SA infections in a tertiary-care hospital. Panton-Valentine leucocidin (PVL) encoding genes were detected, and sequence type and spa type were determined. Out of the 92 collected strains, 52.2% wer...
