چکیده

staphylococcus aureus carrying pvl gene remain major health problem associated with highly virulent infections. characterization of such gene is important to know the impact and the functional significance of nucleotide variations. pcr and standard sequencing were performed for twelve sudanese strains from different sources. protein structures prediction, modeling and physiochemical analysis were done to analyze genetic variation in pvl. single nucleotide polymorphism at position 610 (a / g) of luks-pv was detected in all tested isolates resulted in nonsynonymous mutation in the amino acid sequence at position 204 (n / d). using molecular and bioinformatics tools the detected novel mutation in luks-pv may have a diagnostic functional significance.

Panton-Valentine Leukocidin Genes in Staphylococcus aureus

To the Editor: The pathogenicity of Staphylococcus aureus depends on various bacterial surface components and extracellular proteins. However, the precise role of single virulence determinants in relation to infection is hard to establish. The frequent recovery of staphylococcal isolates that produce leukocidal toxins from patients with deep skin and soft tissue infections, particularly furuncu...

Panton-Valentine Leukocidin–producing Staphylococcus aureus

To the Editor: Panton-Valentine leukocidin (PVL) is a cytotoxin produced by Staphylococcus aureus that causes leukocyte destruction and tissue necrosis (1). Although produced by <5% of S. aureus strains, the toxin is detected in large percentages of isolates that cause necrotic skin lesions and severe necrotizing pneumonia (2). Although commonly associated with community-acquired methicillin-re...

Panton-Valentine leukocidin in pediatric community-acquired Staphylococcus aureus infections.

PURPOSE Panton-Valentine Leukocidin (PVL) is an exotoxin produced by strains of Staphylococcus aureus (SA). Its importance as a virulence factor is controversial. We aim to further characterize the role of PVL in pediatric community-acquired SA infections. METHODS In a cohort study conducted from July to November 2006, we prospectively collected all strains of SA isolated at the Montreal Chil...

Panton-Valentine Leukocidin in Staphylococcus aureus Musculoskeletal Infections

Infections caused by Panton-Valentine leukocidin (PVL)–producing strains of Staphylococcus aureus have been reported with increasing frequency. However, the role of PVL in the pathogenesis of invasive staphylococcal infection is controversial. It is interesting to note that the role played by PVL may depend on the site of infection; although an association between PVL and severity has been repo...
