Description
Summary:Aspergillosis is a major cause of severe respiratory disease in birds. The prevalence of cryptic section Fumigati and other non-Aspergillus fumigatus species as causative agents is unknown. Species identity was determined in 30 isolates from affected birds from zoos, pet birds and poultry by PCR of the ITS1-5.8S-ITS2 and partial β-tubulin genes. The most prevalent isolate was A. fumigatus sens. str. in 87% (26) cases. Other Aspergillus species were identified in 13% (4) cases, including A. restrictus (1), A. flavus sens. str. (2), and A. nidulans-clade (1). This is the first report of A. restrictus causing avian disease.
