Impact of Combined Low-Level Mupirocin and Genotypic Chlorhexidine Resistance on Persistent Methicillin-Resistant Staphylococcus aureus Carriage After Decolonization Therapy: A Case-control Study

Abstract

Combined low-level mupirocin and genotypic chlorhexidine resistance significantly increases the risk of persistent MRSA carriage after decolonization therapy. Institutions with widespread use of these agents should monitor for resistance and loss of clinical effectiveness.
