Plain-English summary
A cat with nasal problems was diagnosed with a fungal infection caused by a special strain of Cryptococcus neoformans, which is known to grow poorly at body temperature. The cat had a granuloma, which is a type of inflamed tissue, and tests showed both yeast cells and long hyphal structures in the affected area. This unusual strain was identified because it didn't grow well at the higher temperature typical of a cat's body. Treatment details weren't provided, but understanding the specific strain can help veterinarians choose the right approach for managing the infection.

Abstract
We report the isolation of a temperature-sensitive, serotype A, mating type alpha strain of Cryptococcus neoformans from a case of nasal cryptococcosis in a cat. The strain grew extremely slowly at 35 degrees C and failed to grow at 37 degrees 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 degrees C also produced some yeast cells with germ tube-like hyphal elements up to 100 microm in length.
