绵羊感染兽疫链球菌

Can J Comp Med. 1974 Jul;38(3):243-50.

Fibrinous pericarditis, fibrinous pleuritis and pneumonia associated with Streptococcus zooepidemicus were observed in two lambs in a small flock of sheep. These lesions were reproduced in lambs inoculated intratracheally with Streptococcus zooepidemicus. Clinical signs included pyrexia, serous to mucopurulent nasal discharge, dyspnea and depression followed by death in six to seven days. Histologically the tissue changes were characterized by an acute inflammatory response involving bronchioles and alveoli, fibrinous pleuritis and fibrinous pericarditis.

在一小群绵羊中的两只羔羊身上观察到了与兽疫链球菌相关的纤维素性心包炎、纤维素性胸膜炎和肺炎。将兽疫链球菌经气管内接种到羔羊体内后再现了这些病变。临床症状包括发热、浆液性至黏液脓性鼻液、呼吸困难和精神沉郁，随后在六至七天内死亡。组织学上，组织变化的特征是涉及细支气管和肺泡的急性炎症反应、纤维素性胸膜炎和纤维素性心包炎。
