Pulmonary Infection Caused by an Unusual, Slowly Growing Nontuberculous Mycobacterium

Mycobacterium triplex, a recently described slowly growing nontuberculous mycobacterium, was isolated from a Finnish patient with pulmonary mycobacteriosis. The disease was successfully treated with antimycobacterial drugs. The strain isolated, which was similar to the type strain but differed slightly from the species description, was regarded as a variant of M. triplex sensu stricto. According to present knowledge this variant of the species has never been isolated before.

三联分枝杆菌（Mycobacterium triplex）是一种近年被正式描述的缓慢生长非结核分枝杆菌，此前从一名芬兰肺部分枝杆菌病患者体内分离获得。该患者所患疾病经抗分枝杆菌药物治疗后成功痊愈。本次分离得到的菌株与模式菌株（type strain）高度相似，但与该物种的官方描述存在细微差异，因此被认定为狭义（sensu stricto）三联分枝杆菌的变异株。据现有研究认知，该物种的这一变异株此前从未被分离得到过。
