摘要:目的 调查非结核分支杆菌在牛中的感染情况。 方法 对174头牛鼻腔分泌物，按中国防痨协会1995年11月颁布的“结核诊断细菌学检验规程”进行非结核分支杆菌分离培养和鉴定。 结果 从174份标本中分离出分支杆菌88株，阳性率为50.5%，其中草分支杆菌占22.7%、偶然分支杆占21.5%、戈登分枝杆菌占17.3%、不产色分支杆菌占14.8%、土分支杆菌占10.2%、龟脓肿分支杆菌占9.1%和鸟胸分支杆菌占2.2%。 结论 非结核分支杆菌在牛中存在的现象应引起重视，其毒力对人类的影响应进一步研究，以便采取有效的措施，保护人群的健康。

    Abstract:Objective To Investigate the infectious status of nontuberculous Mycobacteria in cattle. Methods Nontubercu-lous mycobacteria detected from nasal cavity secretions of174heads of cattle were isolated，cultured and differentiated according to the“Bacteriological Determination Standards for TB Diagnosis”，issued in1995by the Antituberculosis Association of China. Re-sults Totally88strains of Mycobacteria were detected from174samples with a positive rate of50.5%.The constituent ratio of Mycobacteria was as follows:M.Phlei was accounted for22.7%;M.fortuitum21.5%;M.gordonae17.3%;M.non-chromogenicum14.8%;Mterraey complex10.2%;M.chelonae subdy abscessus9.1%and M.avium-intracellulare2.2%. Conclusion Attention be paid to the infection of nontuberculous Mycobacteria in cattle and further study on its toxicity and its influ-ence on humans be carried out in order to formulate effective control measures and protect the health of people. ......
