Exotic bird pathology comprises diseases, both infectious and non-infectious, incompletely studied so far as pathogenetic mechanisms, lesions identified and measures of management. The present study comprises a number of 33 cases of birds kept in captivity belonging to Corvidae, Fringillidae, Psittaculidae, Columbidae, Phasianidae and Apodidae families that were submitted to diagnosis after death of the birds. Out of these, 16 cases presented inflammatory lesions affecting different body organs and tissues. Results revealed frequent gross lesions of the lungs, liver and digestive tract. Histologic examination marked mainly lesions of fibrinous and necrotic pneumonia, necrotic hepatitis and catarrhal enteritis. Three cases were affected by chronic lesions of granulomatous inflammation located mainly in the coelomic cavity and digestive tract. Bacteriologic investigations revealed mostly Gram negative bacteria isolated from the lesions. Most frequent pathogens causing disease in the cases taken into study belonged to Salmonella, Escherichia, Pseudomonas, and Staphylococcus genera. In conclusion, results of inflammatory lesions revealed by gross and microscopic examination in correlation with microbiologic results represent a further step in evaluation of avian patients and risk of cross-contamination. Frequent affected regions in the body were the lower respiratory tract, liver and intestinal tract, suggestive for the type of contamination with the bacterial pathogens.
