摘要: 目的 了解云南省鼠伤寒沙门氏菌PFGE分子分型及耐药状况, 为防控由鼠伤寒沙门氏菌引起的疾病提供科学依据.方法 根据Pulse Net China公布的沙门氏菌PFGE分型技术进行分子分型.分析得出药敏板MIC值, 根据CLSI的相应标准获得出S、I、R结果.结果 云南省68株鼠伤寒沙门氏菌呈53种PFGE带型.68株鼠伤寒沙门氏菌对复合磺胺 (SXT) 的耐药率最高, 为45.59%, 对亚胺培南 (IMP) 最敏感.其中1株菌对14种抗生素中11种抗生素耐药.结论 云南省鼠伤寒沙门氏菌分子分型呈多样性.复方磺胺是云南地区鼠伤寒沙门氏菌最耐药抗菌素.地区鼠伤寒沙门氏菌多重耐药不典型.Abstract: Objective To understand the molecular typing and drug resistance of Salmonella typhimurium in Yunnan Province, to provide scientific basis for preventing and controlling diseases caused by Salmonella typhimurium. Methods Molecular typing was carried out according to Salmonella PFGE typing technology published by Pulse Net China. The MIC value of the drug sensitive plate was obtained from the analysis of the instructions, and the results of S, I and R were obtained according to the corresponding standards of CLSI.Results The 68 strains salmonella typhimurium in Yunnan Province showed 53 types of PFGE. The drug resistance rate of the 68 strains of salmonella typhimurium was the highest for the compound sulfonamide (SXT) , 45.59%, and the most sensitive to imipenem (IMP) , among which one strain was resistant to 11 of the14 antibiotics. Conclusion The molecular typing of salmonella typhimuriumin in Yunnan province is diverse.Compound sulfonamide is the most resistant antibiotic of Salmonella typhimurium in this region. Multiple drug resistance of Salmonella typhimurium in this region is atypical.
