摘要

Our studies show that microaerophilic conditions promote the growth of Mycobacterium genavense in semisolid medium. The growth of M. genavense at 2.5 or 5 oxygen was superior to that obtained at 21 oxygen in BACTEC primary cultures (Middlebrook 7H12, pH 6.0, without additives). By using nondecontaminated specimens, it was possible to detect growth with very small inocula (25 bacilli/ml) of 12 different M. genavense strains (from nude mice) within 6 weeks of incubation under low oxygen tension; conversely, with 21 oxygen, no growth of 8 of 12 (66.7) M. genavense strains was detected (growth index, <10). The same beneficial effect of 2.5 or 5 oxygen was observed in primary cultures of a decontaminated clinical specimen. Low oxygen tension (2.5 or 5) is recommended for the primary isolation of M. genavense. Microaerophilic cultivation of other atypical mycobacteria, especially slow-growing (e.g., Mycobacterium avium) and difficult-to-grow (e.g., Mycobacterium ulcerans) species, is discussed.
