Recent outbreaks of nosocomial infections caused by organisms identified as the Mycobacterium fortuitum complex suggest that species and subspecies identification is epidemiologically important. In a study of 170 strains, M. fortuitum was differentiated from M. chelonei by nitrate reduction and iron uptake. M. fortuitum was further divided into biovariant fortuitum, biovar peregrinum, and an unnamed third biovar by inositol and mannitol utilization. M. chelonei was further divided into subsp. chelonei, subsp. abscessus, and an unnamed subspecies by tolerance to 5% sodium chloride, utilization of mannitol and sodium citrate, and uptake of iron.
近期由被鉴定为偶然分枝杆菌复合体的微生物引起的医院感染暴发表明,菌种和亚种鉴定在流行病学上具有重要意义。在一项对170株菌株的研究中,通过硝酸盐还原和铁摄取将偶然分枝杆菌与龟分枝杆菌区分开来。通过肌醇和甘露醇利用情况,偶然分枝杆菌进一步分为偶然生物变种、迁徙生物变种和一个未命名的第三生物变种。通过对5%氯化钠的耐受性、甘露醇和柠檬酸钠的利用以及铁摄取情况,龟分枝杆菌进一步分为龟亚种、脓肿亚种和一个未命名的亚种。
