Detection of disinfectant-resistant gene in acinetobacter baumannii isolated in clinic
Abstract：Objective To investigate the drug resistance characteristics of acinetobacter baumannii isolated in clinic and the disinfectant-resistant gene (qacEΔ1-sul1) taken along with acinetobacter baumannii ,and to explore its sensitivity to chlorine-containing disinfectant .Methods Antibiotic susceptibility was detected by Kirby -Bauer agar scrip diffusion method.Polymerase chain reaction (PCR) was used to examine qacEΔ1-sul1 and broth dilution method was used to determine the minimum inhibitory concentration .Results Among the clinically isolated 73 strains of acinetobacter baumannii ,37 strains were found to be positive in qacEΔ1-sul1gene, and positive rate was 50.68%.The average MIC of chlorine-containing disinfectant to acinetobacter baumannii was 365.07mg/L.Conclusion Clinically isolated acinetobacter baumannii is multidrug resistant bacteria , and its qacEΔ1-sul1 positive rate is higher , but the chlorine-containing disinfectant in practical concentration can kill acinetobacter baumannii .
