【摘要】 目的研究深圳某医院发生的一起术后暴发感染的致病菌。方法按照中国防痨协会《结核病诊断细菌学检验规程》和《伯杰细菌鉴定手册》第九版，以及《实用临床细菌学检验与进展》介绍的方法，对９７例切口分泌物标本进行细菌培养。在分离出非结核分支杆菌的基础上，以标准株龟分支杆菌龟亚种、龟分支杆菌脓肿亚种和偶然分支杆菌作对照，对临床分离株进行了菌型鉴定。结果从９７例切口分泌物中分离出２６株抗酸染色阳性的速生长非结核分支杆菌，在分离出非结核分支杆菌的基础上，加上医院收集的１５株共４１株，鉴定为龟分支杆菌脓肿亚种。结论此次院内术后暴发感染是由龟分支杆菌脓肿亚种引起的。更多还原

【Abstract】 Objective To study the pathogen of postoperative infection outbreak in a hospital in Shenzhen. Methods According to the Laboratory Science Procedure of Diagnostic Bacteriology in Tuberculosis published by Chinese Antituberculosis Association, Bergeys Manual of Determinative Bacteriology (ninth edition),and the Clinical Bacteriology Examination & Development, 97 wound exudates were cultivated by the traditional bacteriologic method. The strains were identified with three standard strains of M. chelonae subsp.chelonae, M. chelonae subsp. abscessus and M. fortuitum as controls. Results 26 fastacid positive and fast growth nontuberculous mycobacterium were isolated from 97 exudates,then 41 strains including other 15 strains which were collected from the hospital were identified as M. chelonae subsp. abscessus. Conclusion The outbreak of the postoperative infection happened in the hospital was caused by M. chelonae subsp. abscessus.更多还原
