The long-chain components of 75 strains of mycobacteria, cultivated from Mycobacterium leprae-infected or non-infected armadillos, and of eight clinical and 15 environmental isolates of M. gordonae, were compared. Four major groups could be distinguished based on the presence of 10-methyloctadecanoic (tuberculostearic) and 2-methyl 3-hydroxyeicosanoic acids and secondary alcohols (2-octadecanol and 2-eicosanol). Some heterogeneity was found in strains assigned to M. gordonae: the characteristic absence of tuberculostearic acid and secondary alcohols and the presence of the branched C14 and the hydroxylated C20 acids were seen in only 34 of the 49 strains studied. Three strains were identified as M. malmoense, one as M. kansasii, ten as belonging to the M. avium-M. intracellulare-M. scrofulaceum complex and eight as belonging to new groups of armadillo-derived mycobacteria (ADM 1, ADM 2 and ADM 3) by conventional bacteriological tests and fatty acid compositions, though M. malmoense was heterogeneous in its fatty acids composition. Four strains, identified as M. avium by conventional tests, differed from this species by their fatty acid compositions. Thirteen strains showed some similarity to M. simiae and ten strains differed from all other known mycobacteria.
对从感染或未感染麻风分枝杆菌的犰狳中培养出的75株分枝杆菌的长链成分,以及8株戈登分枝杆菌临床分离株和15株环境分离株的长链成分进行了比较。根据10 - 甲基十八烷酸(结核硬脂酸)、2 - 甲基 - 3 - 羟基二十烷酸以及仲醇(2 - 十八烷醇和2 - 二十烷醇)的存在情况可区分出四个主要组。在归为戈登分枝杆菌的菌株中发现了一些异质性:在所研究的49株菌株中,只有34株具有结核硬脂酸和仲醇特征性缺失以及支链C14酸和羟基化C20酸存在的情况。通过传统细菌学检测和脂肪酸组成,3株被鉴定为马尔默分枝杆菌,1株为堪萨斯分枝杆菌,10株属于鸟分枝杆菌 - 胞内分枝杆菌 - 瘰疬分枝杆菌复合体,8株属于犰狳来源分枝杆菌新组(ADM 1、ADM 2和ADM 3),不过马尔默分枝杆菌的脂肪酸组成存在异质性。4株通过传统检测鉴定为鸟分枝杆菌的菌株,其脂肪酸组成与该种不同。13株与猿猴分枝杆菌有一些相似性,10株与所有其他已知分枝杆菌不同。
