Abstract
Necropsy and culture results are presented for 269 consignments of imported birds (mainly psittacine and passerine species) examined between January 1977 and August 1980. Consignments were submitted for diagnosis of clinical illness or deaths occurring among these birds while they were in quarantine before entry into Canada. Enteritis and injury were the most frequent diagnoses. Pathogens or potential pathogens were isolated from 77% of consignments. Newcastle disease virus was isolated nine times, and Chlamydia psittaci was isolated once. Escherichia coli (from 113 consignments) and salmonellae (from 49) were the most common bacteria isolated, and reoviruses (from 22) and paramyxoviruses other than Newcastle disease virus (from 22) were the most common viruses. Salmonella typhimurium was the most common Salmonella serovar. Salmonella hadar was isolated from turkey poults imported from Great Britain. The possible public health significance of the role of imported birds in the introduction of exotic Salmonella serovars, or of serovars resistant to several antimicrobials is discussed.
