Lymphocytic enteritis and systemic lymphocytic vasculitis may be a new or previously unrecognized syndrome in sheep suffering from chronic wasting. Seven cases in three separate flocks were seen over an eight-year period at Veterinary Laboratory Services in Brighton, Ontario. Most of the animals were between five and twelve months of age and exhibited weight loss and inappetance, with or without diarrhea. All were Suffolks or crossbred Suffolks. In one of the flocks, there were also several sheep with lymphoma. Postmortem examination of carcasses and ancillary testing did not reveal an etiology; however, the intestinal and vascular lesions resembled those described in certain viral diseases, such as malignant catarrhal fever and Border disease, and immune-mediated diseases, such as polyarteritis nodosa. Submission for necropsy of sheep that exhibit signs of chronic wasting is encouraged, to help establish the etiology of the disease and its significance to the industry.
淋巴细胞性肠炎和全身性淋巴细胞性血管炎可能是患有慢性消瘦的绵羊中一种新的或以前未被认识的综合征。在安大略省布莱顿的兽医实验室服务中心，八年期间在三个不同的羊群中发现了七例。大多数动物年龄在5至12个月之间，表现出体重减轻和食欲不振，有或没有腹泻。所有动物均为萨福克羊或萨福克杂交羊。在其中一个羊群中，还有几只患有淋巴瘤的绵羊。对尸体进行的尸检和辅助检测未发现病因；然而，肠道和血管病变类似于某些病毒性疾病（如恶性卡他热和边界病）以及免疫介导疾病（如结节性多动脉炎）中描述的病变。鼓励对出现慢性消瘦症状的绵羊进行尸检，以帮助确定疾病的病因及其对该行业的重要性。
