继Koch发现结核杆菌之后,不断有人报导某些未定型的分枝杆菌对人也有致病性。例如1935年Pinner报告某些光滑型不产色素的菌株和粗糙型产色素的菌株能使少数人致病;1943年Feldman等报告类似鸟型分枝杆菌的菌株可以感染人。非典型分枝杆菌分布广泛,在人的胃洗出液培养物中也发现了多种抗酸菌,表现菌落特性、生长速度及色素产生均有明显差异。可见对非典型分枝杆菌的研究具有重要的实际意义。
Following the discovery of Mycobacterium tuberculosis by Koch, it has been reported that some untreated Mycobacteria are also pathogenic to humans. For example, Pinner reported in 1935 that certain smooth non-pigmented strains and rough pigmented strains were able to cause disease in a small number of individuals; in 1943 Feldman et al reported that strains of Mycobacterium avium could infect humans. A wide range of atypical mycobacteria are distributed. A variety of acid-fast bacteria have also been found in human gastric fluid eluate, showing significant differences in colony characteristics, growth rate and pigment production. Visible atypical mycobacterium research has important practical significance.
