title: Purulent meningoventriculitis caused by Streptococcus equi subspecies zooepidemicus in a snow leopard (Panthera uncia).
abstract: Streptococcus equi subspecies zooepidemicus (SEZ) is a zoonotic pathogen that causes respiratory tract infections in man and animals. SEZ infections are very rare in felids. This report describes purulent meningoventriculitis caused by SEZ in an approximately 16-year-old male snow leopard (Panthera uncia). The animal exhibited neurological signs and died 1 month after their onset. On necropsy examination, the surface blood vessels of the brain were swollen and there was an increased volume and turbidity of cerebrospinal fluid (CSF). Microscopically, suppurative inflammation accompanied by gram-positive cocci was observed in the meninges and near the ventricles. SEZ was isolated from the brain tissue and CSF. This is the first report of infection with SEZ in a felid other than a domestic cat. This animal had not had direct contact with horses, but it had been fed horse flesh that may have been the source of infection.
