Panton-Valentine Leukocidin Genes in Staphylococcus aureus. We report a PVL-secreting S. aureus superinfection in a patient who had COVID-19. 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). The leukocidins genes (lukD . Furthermore, patients with bone and joint infections require more than one surgical procedure [26]. Albiski MK, Lutz N, Ceroni D, N'Dele D, Zambelli PY, Bregou A.

In addition, a variety of bacterial pore-forming toxinssuch as Panton-valentine leukocidin from Staphylococcus aureus and -toxin from Clostridium perfringensinduce necrosis in muscles and intestinal epithelium (42-44). Patients with PVL positive severe infections needed a prolonged hospital stay and a longer recovery times [5]. For this purpose, a single polymerase chain reaction method was used to detect both lukS-PV and lukF-PV genes (2).

Skin and soft-tissue infections especially are sometimes caused by strains harbouring Panton-Valentine leukocidin (PVL). The pathogenicity of Staphylococcus aureus depends on various bacterial surface components and extracellular proteins. The PVL toxin is a combination of two proteins (Leuk S and F) that act synergistically to activate and destroy leukocytes by creating lytic pores (Finck-Barbancon et al., 1993), and are associated with necrotic infections of skin, subcutaneous fat and pneumonia (community-acquired). official website and that any information you provide is encrypted Panton-Valentine Leukocidin (PVL) is a toxin produced by some strains of Staphylococcus aureus (S. aureus).
