In November 2012, a 4-month-old foal with anorexia, neurologic signs with ataxia and death was submitted for necropsy to the diagnostic laboratory of Jeju Self-Governing Provincial Veterinary Research Institute. Grossly, yellowish-white fibrinous materials were seen on the ventral cerebrum, cerebellum,medulla oblongata and cervical spinal cord of the foal. Histologically, severe fibrino-purulent meningitis characterized by the infiltration of neutrophils and fibrionous exudates with bacterial colonies were presented in cerebrum, cerebellum, brain stem and cervical spinal cord. In the bacterial isolation using meningeal exudate, the small white colonies on blood agar plate with β-hemolysis were observed. Isolated bacteria were Gram-positive cocci and confirmed as Streptococcus (S.) equi subsp. zooepidemicus by VITEK 2 system. Based on the histopathological features and the bacterial test, this case was diagnosed as meningitis associated with S. equi subsp. zooepidemicus infection in a foal. In our best knowledge,this is the first report for fibrino-purulent meningitis caused by S. equi subsp. zooepidemicus infection in Jeju.
