Abstract

Scopulariopsis brevicaulis , a soil saprophyte, is the most common dermatomycotic mould and causes deep fungal infection. Ten canaries died in a flock of 200 and, at necropsy, S. brevicaulis was isolated from lung and beak samples. Macroscopically, the colonies were flat, velvety or powdery, white, tan, dark brown, grey or black. Microscopically, the isolated fungus had hyaline and septate hyphae, finger-like conidiophores on which an-nelids produced chains of conidia. On histopathological examination, multiple irregular thin red hyphae were seen in lung tissue of the canaries. Although S. brevicaulis may be involved in onychomycosis, pulmonary mycosis or invasive infection in humans, this infection has not been reported in canaries. This study shows that S. brevicaulis can cause invasive and fatal infection in canaries.(c) 2022 Elsevier Ltd. All rights reserved.
