From Aug 1, 1979 to Aug 15, 1980, a total of 624 samples were collected from the vaginas, cervices, and uteri of 208 dairy cows 30 to 37 days after parturition. An additional 90 samples were collected from the reproductive tracts from 30 of the 208 cows. The 30 cows had aborted or were repeat breeders. Samples from cows that had aborted were collected within a week after clinical abortion or immediately after rectal palpation revealed subclinical abortion. All samples were tested for the presence of cytopathogenic viruses. All samples were negative.
1979年8月1日至1980年8月15日，在208头奶牛产后30至37天，从其阴道、子宫颈和子宫共采集了624份样本。另外从208头奶牛中的30头的生殖道采集了90份样本。这30头奶牛已流产或为屡配不孕牛。流产奶牛的样本在临床流产后一周内采集，或在直肠触诊显示亚临床流产后立即采集。所有样本均检测是否存在致细胞病变病毒。所有样本均为阴性。
