Abstract
The turquoise-fronted amazon, Amazona aestiva, is a parrot (order Psittaciformes) that has a long history of domestication in Brazil, where it is often kept as a pet. Most animals are captured in the wild and traded illegally, and many of these parrots are exposed to poor living conditions, in which they are often exposed to respiratory disorders. The present study describes the complete blood count and the biochemical profile of captive A. aestiva with pneumonia, in order to provide insights and guidelines for the diagnosis of the disorder in these birds by veterinarians. A total of 19 adult parrots were selected. The clinical examination revealed that 12 of the 19 parrots had respiratory disorders; these 12 birds were allocated to the pneumonia group (PG). The seven other birds were healthy and were assigned to the control group (CG). The mean parameters recorded for the control and treatment (pneumonia) groups were compared using the t test, with a p < 0.05 significance level. The X-rays indicated pneumonia in all the sick animals of the PG. The MCV, MCHC, leukocytes, heterophiles, lymphocytes, and thrombocytes were all significantly (p < 0.05) higher in the PG in comparison with the CG. The biochemical tests indicated a significant (p < 0.05) increase of AST, CK, and cholesterol in the PG in comparison with the CG. The hematological and biochemical parameters recorded in the present study highlight the need for early testing to prevent lesions and death caused by respiratory diseases, such as pneumonia. The results of the present study indicate that laboratory tests can be used to diagnose wild birds, given that they indicated systemic alterations in the animals with pneumonia.
