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. We used the same strain collection to study the PVL prevalence in carriage and invasive isolates of S. aureus from a single geographic region. It was named after Sir Philip Noel Panton and Francis Valentine when they associated it with soft tissue infections in 1932. This lack of data led us to investigate the frequency of PVL genepositive S. aureus strains obtained from the nares of healthy carriers in the community. There are no evidence-based guidelines to consult for the management of PVL-associated staphylococcal pneumonia. Sharma R, Hammerschlag MR. 19 thng trc
The presence of resistance genes and of the Panton-Valentine leukocidin gene (lukF-lukS) was analyzed by PCR. 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.

Necrotizing pneumonia induced by Panton-Valentine leukocidinsecreting Staphylococcus aureus is a rare but life-threatening infection that has been described in patients after they had influenza. This finding is also in agreement with the proposed involvement of PVL in severe and invasive (soft tissue) staphylococcal infections (13).
The PVL positivity rate is 77100% in community-associated MRSA infections, while it is less than 4% in hospital-associated MRSA infections [10].

PVL is mostly associated with community-acquired methicillin-resistant S. aureus (MRSA) infections and distinguishable from nosocomial MRSA by nonmultidrug resistance and carriage of the type IV staphylococcal chromosome cassette element (SCCmec type IV) (6,7). PubMed it was observed that in children with complicated staphylococcal infections, daptomycin administration alone or in combination with other antimicrobial agents was efficacious and well tolerated [31]. On admission, he was in good general conditions, with normal vital signs, moist mucous membranes, tongue and lips dry, tears when crying, mild tachypnoea (respiratory rate 40/min) and wheezes all over the chest. All SAs, including PVL-SAs, can cause harm if they get an opportunity to enter the body, for example through a cut or a graze. Whole-body MRI in the pediatric patient.

Furthermore, daptomycin was successfully used in 14-year-old boy with tibial osteomyelitis, multilobar pneumonia, pericardial effusion, and septicaemia [16].

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. Moreover, in PICU, daptomycin was included in the regimen for the bacteraemia and the osteo-articular infection.
Antimicrobial peptides produced by neutrophils (HNP1-3) neutralize several other bacterial cytotoxins. Panton-Valentine leucocidin (PVL) is a virulence factor produced by certain strains of Staphylococcus aureus (SA). The echocardiography resulted negative.
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.

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). 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].
