Background & Aim: Listeriosis is a disease that can cause serious economic losses in sheep. Infection with Listeria monocytogenes can lead to many syndromes in animals. The aim of this study was evaluation of caspase expressions in encephalitic listeriosis. Methods & Materials: A total of 20 sheep brains were histopathologically and immunohistochemically examined. Histopathologically, microabscesses, perivascular and meningeal cell infiltrations were commonly seen. Immunohistochemically, prominent positive reactions were detected in the caudal brain for caspases (CSPs) -3, -7, and -9. Results: With regard to cell-specific labeling, necrotic neurons were positive for CSP-3 and -9, Purkinje cells were positive for CSP-3 and -7, CSP-3 was found in neutrophil leukocytes, and CSP-9 was observed in lymphocytes. In addition, only the ependymal cells exhibited immunopositivity for CSP-9. Conclusion: Collectively, our data from naturally infected sheep indicate that CSP-3, -7 and -9 may play roles in encephalitic listeriosis pathogenesis.
