Tüdőaspergillosis európai őzben (Capreolus capreolus Linnaeus, 1758) Esetismertetés

Abstract

SUMMARY Background: The roe deer (Capreolus capreolus,Linnaeus, 1758) is one of the most widespread and important game species in Hungary. An adult, approxi-mately 4 years old roe deer was found dead in a hunting area in Békés county by a local hunter and submitted for necropsy and histopathologic and bacteriologic examination to the National Food Chain Safety Office Laboratory of Pathology and Bacteriology of Veterinary Diagnostic Directorate, in Debrecen (NFCSO, Hun-gary). Objectives: Pathogenic mycosis was identified in a wild roe deer, where the lung was quilted with several necrotic granulomas. The authors have also found parasitic infection in the gastrointestinal tract. Materials and Methods: The authors performed the dissection on the roe deer according to the standard ruminant necropsy techniques. Samples from the internal organs were put into 8% buffered formalin for fixation. After sec-tioning slides were examined with Nikon Optiphot-2 microscope. Samples from the lung were cultured on Sabouraud Dextrose and Columbia’s agar. The inoc-ulated media were incubated for 24 hours at 24 oC in Labor IncuCell V222 type incubator. Results and Discussion: The lung mycosis was caused by Aspergillussp. The hyphae of the fungi infiltrated the tissues. On the histological slides of the lung granuloma proliferation proceeded from the bronchial wall and several necrotic granulomas of 0.5 cm diameter were found in the lung. Aspergillosis can particu-larly cause pathological lesions when the animal is exposed to immunosuppres-sive effects. In this case, probably the external and internal parasitic infection (Ixodesspp. Trichostrongylusspp.) and poor body condition were the causing agents. Common drugs for the therapy of aspergillosis are itraconazole or ketoconazole but their application on the free-living wild animals of hunting areas is impracti-cal. The infection can be prevented by the eradication of the causative agents, in this case, the feed contaminated by fungi.
