Before CAS Effect of antibiotics, alone and in combination, on Panton-valentine leukocidin production by a Staphylococcus aureus reference strain. Panton Valentine leukocidin (PVL) is a cytotoxin, one of the -pore forming toxins (Panton and Valentine, 1932), and its presence is associated with increased virulence of certain strains of S. aureus. (5). These toxins form pores in the membrane of host defense cells by synergistic action of 2 secretory proteins, designated LukS-PV and LukF-PV, which are encoded by 2 cotranscribed genes of a prophage integrated in the S. aureus chromosome (5).

This PVL-SA ST121 strain has been described in literature as mainly disseminated in Africa, Asia and Europe [11]. Panton-Valentine leukocidin (PVL) is a necrotizing exotox-in produced by both methicillin-susceptible and methicillin-resistant Staphylococcus aureus (MRSA) strains. We performed a reverse transcription PCR specific for SARS-CoV-2 on an endotracheal aspirate by using the method developed by the National Reference Centre for Respiratory Viruses (Institut Pasteur, Paris, France).

PubMed Background: A novel Panton-Valentine leukocidin (PVL)-positive meticillin-resistant Staphylococcus aureus (MRSA) clonal complex (CC)5-MRSA-IVc ('Sri Lankan' clone) was recently described from Sri Lanka. 2018;6(2):40. https://doi.org/10.3390/microorganisms6020040. The 2 MRSA clones in the United States most closely associated with community outbreaks, USA400 (MW2 strain, ST1 lineage) and USA300, often contain Panton-Valentine leukocidin (PVL) genes and, more frequently, have been associated with skin and softtissue infections. The frequent recovery of staphylococcal isolates that produce leukocidal toxins from patients with deep skin and soft tissue infections, particularly furunculosis, cutaneous abscesses, and severe necrotizing pneumonia, suggests that the Panton-Valentine leukocidin (PVL) is 1 such virulence factor that has a major role in pathogenicity (1-3). Panton-Valentine Leukocidin (PVL) is a toxin produced by a small number of Staphylococcus aureus strains (1-2%).

Ital J Pediatr. Staphylococcus aureus causes serious hospital-acquired (HA) and community-acquired (CA) infections. staphylococcal enterotoxin H (seh), Panton-Valentine leukocidin (PVL) and Toxic Shock Syndrome Toxin-1 (TSST-1) were the virulence genes of the MSSA isolates determined in the study. Gillet Y, Dumitrescu O, Tristan A, Dauwalder O, Javouhey E, Floret D, et al. Multilocus sequence typing analysis of a subset of the strain collection showed that the 15 PVL-positive strains were within clonal complex (CC) 30 (n = 7), CC 121 (n = 3), CC 1 (n = 2), CC 8 (n = 1), CC 22 (n = 1), and CC 45 (n = 1) (Table) (8). Whether the prevalence of PVL in carriage- and blood-culture isolates is higher and differs among distinct genetic clusters of S. aureus in countries with endemic CA-MRSA has to be investigated further. Methicillin-resistance prevalence was 24%. National Library of Medicine The blood tests showed an elevation of CRP 65mg/dl and a WBC of 3800/L with 55% of neutrophils.

This rare entity is mainly described in young immunocompetent patients with an influenza-like prodrome and has a high case-fatality rate (1,2). PVL is associated with skin and soft tissue infections but not with bacteremia, which suggests that PVL is not likely to be involved in the pathogenesis of bacteremia.
