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

The clinical importance of low-level mupirocin resistance and genotypic chlorhexidine resistance remains unclear. We aimed to determine whether resistance to these agents increases the risk of persistent methicillin-resistant Staphylococcus aureus (MRSA) carriage after their use for topical decolonization therapy.
