Blood samples were collected from a flock of healthy ewes at a University of Minnesota research station. Sera from these blood samples were tested for antibodies against 7 viruses, using 3 tests (eg, virus-neutralization test for bovine viral diarrhea virus, infectious bovine rhinotracheitis virus, bovine adenovirus type 3, and bovine respiratory syncytial virus; hemagglutination inhibition test for parainfluenza virus type 3; and agar-gel immunodiffusion test for lentivirus of ovine progressive interstitial pneumonia and bluetongue virus). The number of seropositive ewes for each antibody type were 1 of 377 (0.3%) for bovine viral diarrhea virus, 2 of 377 (0.5%) for infectious bovine rhinotracheitis virus, 29 of 378 (7.6%) for bovine adenovirus type 3, 200 of 378 (52.5%) for bovine respiratory syncytial virus, 273 of 373 (71.7%) for parainfluenza virus type 3, and 210 of 379 (55%) for ovine progressive pneumonia virus. All ewes were seronegative for bluetongue virus antibodies.
在明尼苏达大学的一个研究站，从一群健康母羊身上采集了血样。使用3种检测方法对这些血样的血清进行了7种病毒抗体检测（例如，对牛病毒性腹泻病毒、传染性牛鼻气管炎病毒、3型牛腺病毒和牛呼吸道合胞体病毒采用病毒中和试验；对3型副流感病毒采用血凝抑制试验；对绵羊进行性间质性肺炎慢病毒和蓝舌病毒采用琼脂凝胶免疫扩散试验）。每种抗体类型的血清阳性母羊数量分别为：牛病毒性腹泻病毒377只中有1只（0.3%），传染性牛鼻气管炎病毒377只中有2只（0.5%），3型牛腺病毒378只中有29只（7.6%），牛呼吸道合胞体病毒378只中有200只（52.5%），3型副流感病毒373只中有273只（71.7%），绵羊进行性肺炎病毒379只中有210只（55%）。所有母羊的蓝舌病毒抗体均为血清阴性。
