This case report describes the development of halo naevi, vitiligo and diffuse alopecia areata associated with tocilizumab therapy following infection with Methicillin-resistant Staphylococcus aureus (MRSA) and Panton-Valentine leukocidin positivit...

conclusions the cefoxitin disk diffusion method showed the best results when compared to oxacillin disk, similar to results from detecting the meca gene in pcr as a golden test. studies on mrsa that carry the luk-pv gene should continue to provide significant insight into the prevalence and epidemiology of these important resistant pathogens. also, the rate of pvl gene-producing isolates showed...

BACKGROUND Staphylococcus aureus has been recognized as a major human pathogen and is the major cause of nosocomial infections. Gamma-toxin, leukocidin and other bi-component toxins are a family of proteins encoded by the hlg and luk-PV, respectively. Panton-Valentine leukocidin (PVL) is an example of these toxins and causes leukocyte destruction and tissue necrosis. The aim of this study was t...
