The incidence of myositis has been increasing since the advent of the epidemic of community-associated methicillin-resistant Staphylococcus aureus infection, and Panton-Valentine leukocidin has been implicated as a factor contributing to more-severe muscle injury. We report a case of severe myositis accompanying septic osteomyelitis and necrotizing fasciitis caused by a Panton-Valentine leukoci...

The Panton-Valentine leukocidin is associated with staphylococcal skin and pulmonary infections. We describe a school outbreak of skin infections and the public health response to it. Nasal carriage of a Panton-Valentine leukocidin-positive Staphylococcus aureus clone was detected only in previously ill classmates and their family members.

During 2005-2014, community-associated methicillin-resistant Staphylococcus aureus infections increased in Shanghai, China. Most infections were caused by sequence type 59 S. aureus that lacked Panton-Valentine leukocidin. This finding challenges the notion that Panton-Valentine leukocidin is necessary for epidemiologic success of community-associated methicillin-resistant S. aureus.

Necrotising pneumonia caused by Panton-Valentine Leukocidin Staphylococcus aureus confers a high mortality. We describe a child presenting with sepsis and necrotising pneumonia. Septicaemia caused by Panton-Valentine Leukocidin Staphylococcus may not be adequately treated with antibiotics to which it appears sensitive through standard culture techniques. Some evidence suggests that early anti-t...

Staphylococcus aureus strains that produce Panton-Valentine leukocidin are known to cause community infections. We describe an outbreak of skin abscesses caused by Panton-Valentine leukocidin-producing methicillin-susceptible S. aureus (clonal complex 121) in a professional rugby team in France during July 2010-February 2011. Eight team members were carriers; 7 had skin abscesses.

INTRODUCTION Strains of Panton-Valentine leukocidin-producing Staphylococcus aureus producing a new pattern of disease have emerged worldwide. Infection with these bacteria typically presents as a life-threatening infection of soft tissues and bones, and may cause potentially devastating consequences. CASE PRESENTATION We report a case of osteoarticular infection caused by Panton-Valentine le...

Panton-Valentine leukocidin secreted by Staphylococcus aureus is known to cause severe skin, soft tissue and lung infections. However, until recently it has not been described as causing life-threatening musculoskeletal infection. We present four patients suffering from osteomyelitis, septic arthritis, widespread intravascular thrombosis and overwhelming sepsis from proven Panton-Valentine leuk...

We report a de novo -assembled draft genome sequence of the Indian Staphylococcus aureus type 88 (ST88) strain LVP-7, isolated from an ocular infection. The harbors Panton-Valentine leukocidin phage, V staphylococcal cassette chromosome mec element, delta-hemolysin-converting Newman phage ΦNM3, and pathogenicity island SaPI3, encoding superantigen enterotoxin B.
