We confirmed PVL production by using a specific PCR as described by Deurenberg et al. (5). Infections with these strains can cause recurrent skin and soft tissue infections, and occasionally may cause more serious invasive infections (including necrotising pneumonia).

In our patient WB-MRI was really helpful for the detection and location of multifocal flogistic processes and was a valid and sensitive tool during the follow-up period, without radiation exposure of the child. discussed this issue for COVID-19 and suggested consideration of methicillin-resistant S. aureus coverage to reduce the risk of superinfection (10). Furthermore, daptomycin was successfully used in 14-year-old boy with tibial osteomyelitis, multilobar pneumonia, pericardial effusion, and septicaemia [16]. BMJ Case Rep. 2013;2013:bcr2013200139. We describe a case of an infant with a severe PLV-SA infection and we perform a literature review since 2010 on this topic in paediatric age. We associated clindamycin, as inhibitor of PVL production. 8600 Rockville Pike Furthermore, concentration below the Minimum Inhibitory Concentration of -lactams and, to a lesser extent, vancomycin have been shown to enhance PVL secretion, determining more aggressive symptoms [7, 30].

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).

Invasive strains (blood culture, skin and soft tissue infections, and impetigo isolates) were included in this study (Table). We changed antimicrobial drug therapy to oxacillin plus clindamycin (for antitoxin effect) against methicillin-susceptible S. aureus and lopinavir/ritonavir (quickly stopped because of suspected toxicity) plus azithromycin against SARS-CoV-2. Emerg Infect Dis. In 1932, Panton and Valentine described PVL as a virulence factor belonging to the family of synergohymenotropic toxins (4). Melles, D. C., van Leeuwen, W.
