Description
Summary:Clinical disease caused by infection with is rare in adult horses, and there is a paucity of ante-mortem clinicopathologic changes for this species reported in the literature. Confirmatory diagnosis is difficult and often requires post-mortem sampling of the brainstem. This report details a case of meningoencephalitis caused by in an adult American quarter horse gelding presenting with central neurologic signs. Pre-mortem analysis of the cerebrospinal fluid revealed a mononuclear, primarily lymphocytic, pleocytosis, which is a reported finding in other species with listeriosis. Post-mortem histopathologic changes of the brainstem were characteristic of listeriosis, and infection was confirmed with immunohistochemical labeling and bacterial culture. Key clinical message: Listeriosis should be included as a differential diagnosis in neurologic horses with mononuclear pleocytosis identified on cerebrospinal fluid analysis.
