聚团肠杆菌的分离及药敏谱分析

Isolation and Antimicrobial Susceptibility Analysis of E.agglomerans

目的研究聚团肠杆菌的临床分布特点及耐药现状。方法运用经典的生理生化法对各种临床标本分离到的188株聚团肠杆菌进行种的鉴定,并用K-B法测定该菌对抗菌药物的敏感性。结果临床各类标本中,该菌的分离率最高的是呼吸道标本(73.5%),其次是泌尿道标本(17.1%)。该菌对泰宁、丁胺卡那、卡那霉素和氟哌酸的耐药率分别为12.5%、19%、29%和35.2%,其余的抗菌药物的耐药率均大于40%。结论聚团肠杆菌的多重耐药率高,给治疗增加难度,应引起临床重视。

Objective To investigate the infection ability and antimicrobial susceptibility of E.agglomerans Methods Typical physiological and biological chemistry tests were used to detect E.agglomerans. Antimicrobial susceptibility of 188 E.agglomerans strains isolated from clinical samples was analyzed. Results 73.5%E.agglomerans strains were isolated from respiratory system and 17.1%from urinary system. The antimicrobial resistances of E.agglomerans to Tienam, Amikicin, Kanamycin, and Norfloxacin were 12.5%, 19%, 29%and 35.2%, respectively. The resistance to other tested antibiotics was more than 40%. Conclusions E.agglomerans isolates had a high drug resistant ability, which increased the difficulty to therapy. Therefore we should pay great attention to E.agglomerans infection.
