  1. 1. The pleomorphic, partly acid-fast diphtheroid of Bordoni-Uffreduzzi and other authors can be cultivated more or less constantly from nasal and other open lesions of lepers, as well as from non-ulcerating leprous lesions.
  2. 2. This diphtheroid differs in its large size, extreme pleomorphism, peculiar colonies, carbohydrate fermentations and partial acid-fastness from all diphtheroids from other sources adequately described in the literature.
  3. 3. A search for the possible saprophytíc source of this diphtheroid from leprous lesions has disclosed that it is apparently identical with a diphtheroid cultivable from smegma praeputii, which is probably a cultural form of the pleomorphic and facultative acid-fast Bacillus smegmatis.
