Wound colonization with methicillin-resistant Staphylococcus aureus and hypotheses about acquisition routes in rural health care settings in Sub-Saharan Africa: Perspective from a center devoted to the treatment of cutaneous neglected tropical diseases

Abstract

We identified a high prevalence (46.4%) of wound colonization with methicillin-resistant Staphylococcus aureus (MRSA) in patients hospitalized in a center devoted to the treatment of cutaneous tropical diseases in Benin. The proportion of MRSA among S aureus isolates was 54.3%. Thirty percent of these MRSA were identified in outpatients. The analysis of pulsed-field gel electrophoresis demonstrated an important diversity of strains but also identified 8 small clusters containing between 2 and 4 isolates suggesting cross-transmission.
