Prospective Study of Methicillin-Resistant Staphylococcus Aureus (MRSA) Among HIV-Infected Persons

Prospective Study on the Incidence, Predictors, and Characteristics of Methicillin-Resistant Staphylococcus Aureus Infections and a Randomized, Double-Blind Study on Decolonization Procedures for Prevention of MRSA Infections Among HIV-Infected Persons

This study will prospectively evaluate the prevalence and incidence (over a two year period) of MRSA colonization and infection among HIV-infected military beneficiaries to determine predictors for the development of MRSA colonization and infection. This study will also investigate the utility of decolonization procedures for clearance of MRSA carriage and prevention of MRSA infections. Finally, the molecular characteristics and the antimicrobial sensitivities of isolates in this population will be determined.
