Aspectos epidemiológicos, clínicos e patológicos da aspergilose em codornas de corte (Coturnix coturnix) no Sertão da Paraíba.

Abstract

Aspergillosis in quails (Coturnix coturnix) in the interior of Paraíba.Describe three cases of aspergillosis occurred in quails in the backlands of Paraiba. A total of 240 quails, 120 became ill and 90 died. Of these, 18 birds were necropsied, and in only 3 birds were found lesions characteristic of the disease. The examinations and diagnoses were made in the Pathology Laboratory Animal Veterinary Hospital of the Federal University of Campina Grande, in March 2014. In the clinical examination were observed Inappetence signals, drowsiness, depression, little movement, as nervous symptoms, circling, paresis and cervical deviation. On external examination were seen lean animals, ruffled feathers, brittle and opaque. During the autopsy, the opening of the coelomic cavity of 3 birds, spherical, firm, yellowish lesions were found, well circumscribed, ranging from 0.3 to 1.0 cm in diameter, attached air sacs. The histopathological analysis of the three animals lesions were observed granulomas encapsulated by fibrous tissue and discreet inside, presence of necrosis with heterophile and degenerate macrophages amid necrotic material, bounded by multinucleated giant cells. Interspersed with areas of necrosis, myriads of fine structures were observed with dichotomous septa, morphologically compatible with Aspergillus, feature observed in the impregnation by special silver staining. Thus, the study reports the occurrence of aspergillosis in quails, reinforcing the need for veterinary guidance to preventive measures in creating quails in experimental and commercial sheds.
