Virulence determinants, biofilm production and antimicrobial susceptibility in Staphylococcus aureus causing device-associated infections in a Tunisian hospital.

Staphylococcus aureus is a clinically relevant pathogen that causes device-related infections (DRI) driven by several virulence factors. This study characterized S. aureus isolates involved in DRI in Tunisian patients.

Clinical isolates of Pantone-Valentine leucocidin- and gamma-haemolysin-producing Staphylococcus aureus: prevalence and association with clinical infections.

Pantone-Valentine leucocidin (PVL) and gAMMA-haemolysin (Hlg) are members of the synergohymenotropic toxin family produced by Staphylococcus aureus and encoded by pvl and hlg genes, respectively. Many reports describe an association between PVL toxin and necrotic lesions involving skin and mucosa. The aim of this study was to determine the prevalence of S.

Background: Community-acquired pneumonia due to Panton-Valentine producing S.aureus is a serious infection recently described. Many cases have been reported worldwide.
