ABSTRACT
OBJECTIVE To investigate the qacA/B genes in meticillin-resistant Staphylococcus aureus(MRSA) and their significance.METHODS Totally 221 MRSA strains were clinically isolated.The genes of qacA/B were analyzed using polymerase chain reaction(PCR).RESULTS From them 101 strains were found the qacA/B genes,the positive rate of qacA/B genes was 45.7%.And 71 strains were selected for qacA PCR detection,20(28.2%) were with qacA gene and 27(38.0%) were with qacA/B gene,suggesting that the seven strains be with qacB gene.CONCLUSIONS MRSA strains have emerged the high-frequency qacA/B disinfectant resistance gene.Application of chlorhexidine and other disinfectants to prevent postoperative nosocomial infections must be reassessed.The efficacy of existing disinfectants or disinfection methods should arouse our wider attention.Disinfectant resistance gene detection technology provides a practical means for the research of the disinfectant-resistant bacteria and the clinical application of the molecular epidemiology research.
