Abstract

ABSTRACT We report the isolation of a temperature-sensitive, serotype A, mating type α strain of Cryptococcus neoformans from a case of nasal cryptococcosis in a cat. The strain grew extremely slowly at 35°C and failed to grow at 37°C in vitro. Histopathological sections of the infected tissue revealed yeast cells producing hyphae up to several hundred micrometers in length, in addition to numerous encapsulated yeast cells typical of C. neoformans . The cultures grown on yeast extract-peptone-glucose agar at 35°C also produced some yeast cells with germ tube-like hyphal elements up to 100 μm in length.
