Vasculitis, involving small muscular arteries and arterioles, was found in 5 of 18 sheep naturally infected with ovine progressive pneumonia (OPP) virus and in 5 of 11 sheep experimentally infected with OPP virus. In order of frequency, arterial lesions were seen in carpal joint capsules, kidneys, meninges, brains, lungs, and tracheas. The lesions were intramural edema and hemorrhage, mononuclear cell infiltration, fibrinoid necrosis of media, and thrombosis. The vascular lesions were frequently associated with interstitial pneumonitis, arthritis, and encephalitis also induced by OPP virus.
在自然感染绵羊进行性肺炎（OPP）病毒的18只绵羊中，有5只出现了累及小肌性动脉和小动脉的血管炎；在实验感染OPP病毒的11只绵羊中，有5只出现了血管炎。按出现频率依次为，在腕关节囊、肾脏、脑膜、脑、肺和气管中发现动脉病变。病变包括壁内水肿和出血、单核细胞浸润、中膜纤维蛋白样坏死以及血栓形成。这些血管病变常与OPP病毒引起的间质性肺炎、关节炎和脑炎相关。
