Panton–Valentine leukocidin

Overview

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 ,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 ,Although commonly associated with community-acquired methicillin

Panton valentine leukocidin PVL toxin positive MRSA

The PVL toxin has been shown to be responsible for many of the severe clinical symptoms of infection with MRSA, such as furunculosis, severe necrotizing pneumonia, and necrotic lesions of the skin and soft tissues, The aim of this study was to determine the presence of the S, aureus PVL toxin genes lukS-PV and lukF-PV in MRSA strains isolated from companion animals, Eleven MRSA isolates

Staphylococcus aureus Panton-Valentine leukocidin causes

The Staphylococcus aureus Panton-Valentine leukocidin PVL is a pore-forming toxin secreted by strains epidemiologically associated with the current outbreak of community-associated methicillin-resistant Staphylococcus aureus CA-MRSA and with the often-lethal necrotizing pneumonia, To investigate the role of PVL in pulmonary disease, we tested the pathogenicity of clinical isolates

Panton-valentine leukocidin Staphylococcus aureus severe

PVL toxin determines a pore formation in the cytoplasmatic membranes, resulting in leucocyte destruction, tissue necrosis and it contributes to the inhibition of infection clearance by the host immune-system , Therefore, PVL-SA associated infections may be more aggressive and life-threatening, In a retrospective study of Hardy et al,, among the six patients with PVL-SA bone and joint

Panton-Valentine Leukocidin PVL is a toxin that destroys white blood cells and is a virulence factor in some strains of Staphylococcus aureus, Strains of PVL-SA producing a new pattern of disease have emerged in the UK and worldwide, In the UK the genes encoding for PVL are carried by < 2% of clinical isolates of S, aureus submitted to the national Reference Laboratory, whether meticillin

Global Distribution of Panton-Valentine Leukocidin

Abstract, We determined the agr type, multilocus sequence type, protein A gene type spa typing, toxin gene profile, and antimicrobial drug resistance profile of 469 isolates of Panton-Valentine leukocidin–positive community-acquired methicillin-resistant Staphylococcus aureus isolates PVL-positive CA-MRSA, The isolates had been collected from around the world from 1999 through 2005 …
