Staphylococci are gram-positive bacteria divided into coagulase positive and coagulase negative classes, Staphylococcus aureus is the most important bacterium of this class. Epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) has changed a lot. It is no more the problem of only hospitalised patients. Children coming from community has also been increasingly affected by MRSA-called community acquired methicillin-resistant (CA-MRSA) infection. The higher severity of CA-MRSA is due to its ability to produce the toxin Panton-Valentine Leukocidin (PVL) associated with staphylococcal cassette chromosome mec (SCCmec) type IV gene. Here, we are presenting five cases of CA-MRSA infection in children having age range 0.5 months to 11 years. All of them had invasive MRSA infection finally diagnosed as causing empyema thoracis, infective endocarditis, psoas abscess and necrotising fasciitis. Early surgical intervention, quick microbiological recognition of the pathogen, and appropriate antimicrobial therapy helped save their lives.
