PVL is one of the most important virulence factors of SA and it is encoded by LukS-PV and LukF-PV genes [6]. 2018;2018:45185418. If PVL-SA enters the body through a graze or wound it can attack the skin and may rarely enter the blood stream, causing more serious problems.

Despite the presumed importance of PVL as a virulence factor, few data are available on its prevalence among S. aureus isolates from the nares of healthy persons compared with stains isolated from infections. Toxin genes were detected in all isolates; 11 (85%) had only genes for Panton-Valentine leukocidin. Clin Microbiol Infect.

The role of the pore-forming Staphylococcus aureus toxin Panton-Valentine leukocidin (PVL) in severe necrotizing diseases is debated due to conflicting data from epidemiological studies of community-associated methicillin-resistant S. aureus (CA-MRSA) infections and various murine disease-models. Karmakar A, Jana D, Dutta K, Dua P, Ghosh C. Prevalence of Panton-valentine Leukocidin gene among community acquired Staphylococcus aureus: a real-time PCR study. In the United States, most cases of CA-MRSA are caused by a CC8 strain designated ST8:USA300, which carries SCCmec type IV, Panton-Valentine leukocidin, PSM-alpha and enterotoxins Q and K, and ST1:USA400.

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. Skin and soft tissue infections in intercontinental travellers and the import of multi-resistant Staphylococcus aureus to Europe. 150, 151 PVL is encoded by two genes,lukS andlukF, which can assemble either between themselves or with the components This finding is also in agreement with the proposed involvement of PVL in severe and invasive (soft tissue) staphylococcal infections (13).

We report 2 outbreaks of Panton-Valentine leukocidin-positive, doxycycline-resistant, methicillin-susceptible Staphylococcus aureus infections in French soldiers operating in Cte d'Ivoire.

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).

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). In order to eradicate the bacterial colonization, the patient and his close family members received daily bathing with chlorhexidine 2% and intranasal application of mupirocin, because of the positivity of the fathers nasal swab for PVL- MRSA. Two days later, we performed upper left lobectomy, and antimicrobial drug therapy was incremented with meropenem, gentamicin, and linezolid. Principal component analysis of amplified fragment length polymorphism (AFLP) data of 1,033 Staphylococcus aureus strains. The PVL positivity rate is 77100% in community-associated MRSA infections, while it is less than 4% in hospital-associated MRSA infections [10]. Its genes secrete two proteinstoxins designated LukS-PV and LukF-PV, 33 and 34 kDa[failed verification] in size.

Your article has been reviewed by three peer reviewers, one of whom is a member of our Board of Reviewing Editors, and the evaluation has been overseen by Wendy Garrett . PVL-SA infection's severity and impact are clear, even in small case series as ours. Our findings indicate that the new SARS-CoV-2 is, in the same way, a facilitating factor for PVL-producing S.aureus necrotizing pneumonia. These strains are responsible for primary skin infections and necrotizing pneumonia. Five days after the start of the triple antibiotic therapy, the infant underwent a surgical drainage of the extended abscess of the left shoulder, and the culture of the purulent exudate resulted positive for the same PVL-MRSA. We reviewed all cases of PVL-SA infection diagnosed at our center, and found 21 cases over a 43-month period.
