Summary Cryptococcosis was diagnosed postmortem in a striped grass mouse ( Lemniscomys barbarus ) housed in the nocturnal department of Antwerp Zoo. Eight of the remaining mice in the cage were captured. Cryptococcus neoformans was isolated from the lung of one animal. Two mice had an elevated serum cryptococcal antigen titre. On examination of the pooled faecal samples collected from 17 animal species housed in 23 cages of the nocturnal department, the pathogenic yeast was isolated from the faeces of the striped grass mice and a degu ( Octodon degus ). Numerous Cr. neoformans colonies were isolated from a tree‐trunk, tree‐stumps, and decaying wood collected from a hollow tree used to decorate the animals cage. Subsequent examination in four other cages of the nocturnal department revealed that all the sampled tree‐trunks were colonized by Cr. neoformans . The fungus was isolated from the air sampled in the cage of the degu. Air samples collected in the public and service corridors remained negative. All the isolated strains were identified as Cr. neoformans var. neoformans serotype A.
