Abstract:
Objective To understand the prevalence of disinfectant-resistant gene qacA/B in the clinical strains of methicillin-resistant Staphylococcus aureus (MRSA) .Methods A total of 123 clinical consecutive MRSA strains were collected for PCR assay to detect qacA/B gene and mecA gene .Results The qacA/B gene was identified in 19 (15 .4% ) of the 123 MRSA strains . The mecA gene was positive in 89 .4% (110/123) of the MRSA strains .Conclusions The disinfectant-resistant gene qacA/B is prevalent in the hospital-acquired MRSA strains .Monitoring measures should be strengthened for appropriate selection of disinfectants in clinical practice .
