A Case Of Pulmonary Aspergillosis in a 20-day Old Suckling Lamb

In this study, a case of pulmonary aspergillosis was described in a 20-day-old suckling lamb. Lamb suffering from high fever, anorexia, weakness and balance disorder was brought to the Department of Pathology of Kafkas University Faculty of Veterinary Medicine for necropsy. According to the anamnesis obtained from the animal owner, an intense and random drug treatment was administered to the animal. Following the systemic necropsy of the animal, various tissue samples were taken from for histopathological and microbiological analysis. On macroscopic examination, a yellowish-white colored focus in a diameter of 2x2 mm was detected in only one area of the animal's lung. Histopathological examinations revealed a granuloma in the lung. In the center of this granuloma, in addition to severe necrosis, neutrophils and fungal hyphae were detected. In the PAS staining of the lung tissue, it was noted that these hyphae took the stain and gave a positive reaction in terms of fungus. Ziehl-Neelsen staining of the lung and liver tissues revealed that these tissues were negative for tuberculosis. As a result of histopathological and microbiological analysis, this case, which is rarely seen in dairy lambs, was diagnosed as pulmonary aspergillosis.
