Abstract
Eight Formosan squirrels peracutely died showing facial swelling and nasal and oral bleeding, and hemolytic Streptococcus zooepidemicus was isolated. Histopathology revealed suppurative inflammation in the submaxillay glands and submandibular lymph nodes and fibrinous pneumonia with capillary and arterial thrombosis. Thrombosis was also detected in the coronary venous branches, hepatic sinusoids, splenic sinuses, renal glomeruli and cerebellar capillaries of two cases, and suppurative meningitis with bacterial embolism were present in the cerebrum and cerebellum of one case. These findings suggested that the port of entery was the salivary glands and regional lymph nodes via drinking water or food, resulting in systemic spread via the blood stream. With disseminated intravascular coagulation syndrome.
