[The thermotolerance of the Cryptococcus. Investigation on 208 wild and type cultures strains (author's transl)].

The maximal temperature for growth was investigated on 208 Cryptococcus, 2 type cultures and 206 wild strains, belonging to 11 species or varieties. According to the results, which spread from 25 degrees to 42 degrees, the Cryptococcus were separated in three groups. The differentiation of C. neoformans from other Cryptococcus developing at 37 degrees, and particularly from two species with near bio-chemical characteristics, was discussed.
