ABSTRACT

Background: Aspergillus fumigatus is considered the major agent of mycotic diseases in birds, affecting mainly the respiratory tract. It is a disease of economic importance in the poultry industry, however it is not a zoonotic or contagious disease.
Aspergillus spp. are an environment residents. Infection usually occurs by inhalation of conidia released by molds, which come off the diet or specific ingredients, the nest and contamination of eggs during incubation. The objective of this study is to relate the macro and microscopic diagnosis of aspergillosis in poultry.
Case: In an intensive farming of poultry (Gallus gallus), it was observed mortality rate exceeding 20%, hoarseness and difficulty breathing in males of approximately two weeks of age. The batch was treated with Terramycin ® (oxytetracyclinehydrochloride) in the first week and Trissulfin® (sulfamethoxazole, trimethoprim and bromhexine hydrochloride) in the second week. Birds were sent for analysis at the Laboratório Central de Diagnóstico de Patologias Aviárias (LCDPA) of the Universidade Federal de Santa Maria (UFSM). Necropsy was performed in three affected birds and pulmonary aspergillosis was suspected due to local pulmonary and disseminated injuries in the coelomic cavity, associated to the clinical signs. In birds assessed by necropsy examination, it was common the visualization of nodules in the internal cavity and lungs, caseous masses in the air sacs, little pigmentation on the feet and beaks and fragile bones. Portions of lung and granulomas were sent for
