Abstract
ABSTRACT: This study describes the epidemiological and clinical-pathological aspects of outbreaks of avian pox diagnosed in poultry associated with fungal co-infections. A retrospective study was carried out, and cases of avian pox with suspected associated fungal infection were selected. The slides were subjected to routine and special histochemical staining in cases of suspected fungal infection, in addition to performing the immunohistochemical technique. Macroscopically, there were nodular lesions with crust formation, and histologically, the lesions were characterized by hyperplasia of the spinous layer associated with multiple eosinophilic intracytoplasmic inclusions. In seven cases, morphologically compatible structures with fungi were verified through black impregnation with GMS and strongly stained in pink with PAS. The morphotintorial aspects were suggestive of fungi belonging to the genus Aspergillus sp. and Candida sp. The diagnosis of fungal co-infections was confirmed through immunohistochemistry, with positive immunostaining for fungi of the genus Aspergillus sp. (five cases) and Candida sp. (two cases). It is concluded that the occurrence of fungal co-infections secondary to the cutaneous lesions of avian pox represents a complicating factor of the disease, favoring the weakness of these animals and death. Therefore, the investigation of associated secondary agents is necessary.
