1967年Birh氏在研究鸟-胞内分枝杆菌(MAI)时,发现5株菌株虽类似MAI,但在类脂质形态、血清类型及一些生化特性上与MAI有不同之处。当时虽认为可能系另一种不同细菌,但未给予定名,仅称为“暂定种2”,并认为其中至少4株有临床致病性,1977年Schroder再次发现7株与“暂定种2”同样的细菌,因为系从瑞典马尔摩地方的4例病人痰中分离出,故定名为马尔摩分枝杆菌(Mycobacterium malmoense,MM)。 In 1967 Birh’s study of bird - Mycobacterium intracellulare (MAI), and found that five strains of similar MAI, but in lipidoid morphology, serum type and some biochemical characteristics and MAI are different. At that time, though it was thought that it might be a different kind of bacteria, it was not given a name, which was called “the tentative plan 2” and considered that at least 4 of them were clinically pathogenic. In 1977, Schroder once again found that 7 were “tentative Species 2 ”The same bacteria, named as Mycobacterium malmoense (MM), was isolated from the sputum of 4 patients in Malmo, Sweden.
