From The International Virtual Conference in Veterinary Medicine web site. An Overview of Avian Pathology by H. L. Shivaprasad. An Overview of the West Nile Virus by Carol Highfill. Birds are not only susceptible to the West Nile Virus, but act as hosts, participating in its spread. Aspergillosis is the most frequently occurring fungal infection in birds.
All species are susceptible.
It may be contracted as the result of inhalation of fungal spores or oral ingestion, especially if birds are fed moldy food or housed on contaminated bedding. Aspergillosis is the most frequently occurring fungal infection in birds. It occurs in acute and chronic forms. The acute form primarily occurs in young birds and newly imported birds and is the result of exposure to a large number of spores. Candidiasis is caused by the opportunistic yeast Candida albicans.
