“…(13) Sodium p-aminosalicylate (PAS) degradation was observed according to a method described previously (Tsukamura, 1961 ;Tarshis, 1964; . Blackening of the Ogawa egg medium or Lowenstein-Jensen medium containing 0.2 yo (w/v) PAS after incubation at 37" for 7 days was defined as a positive degradation.…”

SUMMARYAn Rdaiisonian classification of mycobacteria has been done by using 94 characters. Fifty-nine strains of slowly growing mycobacteria. were classified into five groups: (1) Mycobacterium tuberculosis and M . bovis (2) M . kansasii; (3) M . avium, 16 strains of non-photochromogens from human sources, 6 strains of non-photochromogenic mycobacteria from soil sources, and scotochromogens from human sources ( M . aquae) ; (4) 2 strains of non-photochromogens from human sources; ( 5 ) 1 strain of non-photochromogen from human source.The third group seemed to consist of three subgroups: (3, i) nonchromogens from soil sources; (3, ii) Mycobacterium avium and some non-photochromogens, which were inseparable from M , avium; (3, iii) some non-photochromogens from human sources resembling M . avium (but separable from it) and scotochromogens from human sources.Slowly growing non-photochromogenic mycobacteria from soil sources (subgroup 3, i) were considered to form a new species, M . terrae. A description of this species is given.Seventy-eight strains of rapidly growing mycobacteria were classified into seven groups : (6) 6 strains of miscellaneous species, Mycobacterium marinum, M . balnei, M . platypoecilus, M . ranae and M . piscium; (7) M . thermoresistibile (sp.nov.); (8) M . phlei; (9) M . aurum (sp.nov.); (10) M . fortuitum and group IV rapid growers; (11) 1M. parafortuitum; (12) M .smegmatis. These groups seemed to form independent species. Mycobacterium thermoresistibile is a new species capable of growing at 52'. Mycobacterium aurum is a new species consisting of rapidly growing scotochromogenic mycobacteria with urease, nicotinamidase and pyrazinamidase and some strains also with acetarnidase and allantoinase.
