Co-infection ofand Japanese encephalitis virus in a spotted seal () in the Republic of Korea.

Abstract

A 10-year-old male spotted seal presented with loss of appetite and decreased activity. Grossly, the internal organs revealed several filarial nematodes in the right ventricle of the heart and the pulmonary vessels. Histopathological examination of the brain revealed moderate nonsuppurative meningoencephalitis with glial nodules and neuronophagia. Japanese encephalitis virus (JEV) of genotype I was isolated from the brain. All nematodes were identified as. This is the first clinical case of co-infection withand JEV in a seal, suggesting that the seal, may be a dead-end host, like the human and horse, for JEV.
