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). Epidemiology is underknown and underdiagnosis is likely. Disseminated Panton-valentine Leukocidin-positive Staphylococcus aureus infection in a child. It also induces an influx of immune cells to lung tissues, including neutrophils; the rapid killing of these cells by PVL and release of inflammatory mediators might promote disease development by damaging the epithelium (7,8).

Principal component analysis of amplified fragment length polymorphism (AFLP) data of 1,033 Staphylococcus aureus strains. Because it can be found in virtually all CA-MRSA strains that cause soft-tissue infections, it was long described as a key virulence factor, allowing the bacteria to target and kill specific white blood cells known as neutrophils. 2021 Jul 17;47(1):158. doi: 10.1186/s13052-021-01105-5.

CAP afflicted younger and healthier patients and yet had a worse outcome (>40% mortality. Panton-Valentine leucocidin (PVL) is an exotoxin produced by certain strains of Staphylococcus aureus (SA). PVL is a cytotoxin which attacks leukocytes by creating pores in these . 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 [12]. 2016;114(2):e757.

The microorganism isolated was always a MSSA, due to the low rate of MRSA in the paediatric population of the geographic area where the study was conducted [13]. Introduction. FOIA PVL creates pores in the membranes of infected cells. 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 (13). Through its cytolytic action on the cell membranes of human polymorphonuclear neutrophils, PVL causes a range of pathologies collectively known as PVL-SA disease. In 1932, Panton and Valentine described PVL as a virulence factor belonging to the family of synergohymenotropic toxins (4). Moreover, in PICU, daptomycin was included in the regimen for the bacteraemia and the osteo-articular infection. These may be meticillin susceptible (MSSA) or MRSA strains. This literature review focuses on the salient features of diagnosis and management, with particular attention to the choice of antimicrobials.
