Low prevalence of community-acquired methicillin-resistant Staphylococcus aureus colonization and apparent lack of correlation with sexual behavior among HIV-infected patients in Nebraska.

摘要

Community-acquired (CA) methicillin-resistant Staphylococcus aureus (MRSA) has become the predominant cause of skin and soft-tissue infection in the United States [1]. Human immunodeficiency virus (HIV) infection has emerged as a risk factor for increases in the incidence of CA-MRSA events up to 18-fold, compared with the incidence among HIV-uninfected patients [2]. Several lines of evidence suggest that CA-MRSA infection may be associated with sexual behavior [2-6], such as distribution of lesions predominantly around the pubic, genital, and/or perianal areas [2, 4]; the association with recent syphilis infection [2]; the protective effect of wearing condoms [5]; and a higher incidence among men who have sex with men (MSM) and among individuals with multiple sex partners [5, 6].
