Resumo
Os psitacídeos são animais populares e adorados por sua característica sociável, inteligência, capacidade de repetir sons e pelo exuberante colorido de suas penas, tornando um dos principais grupos de aves “pets”. O objetivo do presente estudo foi avaliar a ocorrência de circovirus, enterobactérias e endoparasitos em uma coleção de psitacídeos exóticos. Foram coletados swabb de 70 psitacídeos exóticos de nove espécies, mantidos em um criadouro comercial. O diagnóstico viral foi realizado com auxilio da técnica de PCR. Para o diagnóstico de enterobacterias foram utilizadas técnicas laboratoriais de cultura bacteriana, por meio de características morfológicas e provas bioquímicas. A pesquisa de endoparasitos foi realizada por meio de três métodos: Técnica de Willis (Flutuação em solução salina), Técnica de Hoffman (Sedimentação Simples) e Exame Direto de Fezes. Um terço das aves 24/70 (32,38%) foram positivas para circovirus. Um total de 23/70 (32,85%) das aves foi positiva para enterobacterias de 12 espécies. Foram realizados 210 exames coproparasitológicos das quais 40/70 (57.14%) foram positivos para enteroparasitos, sendo o método Willis o mais preciso. Foi possível concluir que psitacídeos exóticos mantidos sob cuidados humanos apresentam ocorrência significativa de circovirus, enterobacterias e endoparasitos que requerem manejo e profilaxia visando aumentar os índices reprodutivos do plantel, assim como, evitar óbitos de aves. Outro ponto importante é coibir a contaminação das espécies silvestres nativas.
Psittacids are popular birds and adored for their sociable character, intelligence, ability to repeat sounds, and the coloring of their feathers, making them one of the main groups of pets. The objective of the present study was to evaluate the occurrence of circovirus, enterobacteria and endoparasites in a collection of exotic parrots. Swabb of 70 exotic psittacines from nine species were collected from a exotic birds private collection. The viral diagnosis was performed using the PCR technique. For the diagnosis of enterobacteria, bacterial culture and laboratory techniques were used. Endoparasite research was performed using three methods: Willis Technique (Saline Fluctuation), Hoffman Technique (Simple Sedimentation) and Direct Faecal Examination. One third of birds 24/70 (32.38%) were positive for circovirus. A total of 23/70 (32.85%) of the birds were positive for enterobacteria of 12 species. There were 210 coproparasitological exams of which 40/70 (57.14%) were positive for enteroparasites, and the Willis method was the most accurate. It was possible to conclude that exotic parrots kept under human care have a significant occurrence of circovirus, enterobacteria and endoparasites that require management and prophylaxis in order to increase the reproductive indexes of the establishment, as well as to avoid bird deaths. Another important point is avoid the contamination of native species of wild animals.
