A dead stray cat was necropsied for zoonotic feline disease monitoring. Grossly, there were no specific lesions. Major microscopic lesions included lymphocytic meningoencephalitis, malacia, and tissue cysts in the cerebral and cerebellar cortex. The size and shape of tissue cysts were identical to those of Apicomplexa including Toxoplasma (T.) gondii. Bradyzoites in the tissue cyst were strongly positive for T. gondii by immunohistochemistry. Electron microscopy revealed that bradyzoites within the tissue cyst were similar to the morphological features of T. gondii. Fresh tissue samples were examined by a polymerase chain reaction assay and resulted in a specific band of T. gondii only in the brain. Based on the results, this case was diagnosed as toxoplasmosis. This is the first case of toxoplasmic meningoencephalitis in a cat in Korea.
