title: Mycobacteria from leprous tissue of an armadillo cultivated on a hyaluronic acid based medium.
abstract: Mycobacteria were isolated from pooled leprous tissues of an armadillo. The suspensions of acid fast bacilli obtained were inoculated into a culture medium composed of umbilical cord extract, supplemented with yeast extract powder and glycerol with sheep serum added. Incubation temperature was 34 degrees C. An abundant growth of mycobacteria was observed in the primo culture in four weeks. The culture was easily sub-cultured on the homologous media. The primo culture did not grow on Loëwenstein medium. The identity of the cultures of mycobacteria obtained is not yet established. The same strain of mycobacteria was cultured in media inoculated with suspensions of M. leprae decontaminated with sodium hydroxide-citrate solution. We confirm the findings of Skinsnes et al. (1975) that mycobacteria from human and animal leprous tissue can be cultured repeatedly on a hyaluronic based medium.
