We assessed the prevalence of six biocide resistance genes among 82 methicillin-resistantStaphylococcus aureus (MRSA) and 219 methicillin-susceptibleS. aureus (MSSA) isolates from three African countries; the prevalence was very high forsepA (95.3%),mepA (89.4%), andnorA (86.4%), intermediate forlmrS (60.8%) andqacAB (40.5%), and low forsmr (3.7%). A significant association between biocide resistance genes and antibiotic resistance was observed, and a new cutoff MIC of ≥1 mg/liter for chlorhexidine nonsusceptibility was defined.
