A three-year prospective study involving 143 calves born from infected cows was undertaken on a California dairy to evaluate possible factors of the dam associated with bovine leukemia virus infection in utero or during the periparturient period. In utero or periparturient infection occurred at a rate of 4.8% and was more likely in calves born to cows with an average peripheral blood lymphocyte count during pregnancy greater than 12,000 cells/microL (p = 0.043) or in calves born to cows that developed malignant lymphoma (p = 0.00004), but not in calves born to cows with p-24 antibodies (p = 0.675).
在加利福尼亚的一个奶牛场进行了一项为期三年的前瞻性研究，涉及143头由感染母牛所生的小牛，以评估与子宫内或围产期牛白血病病毒感染相关的母体可能因素。子宫内或围产期感染发生率为4.8%，在孕期外周血淋巴细胞平均计数大于12,000个/微升的母牛所生的小牛中更有可能发生（p = 0.043），或者在患恶性淋巴瘤的母牛所生的小牛中更有可能发生（p = 0.00004），但在有p - 24抗体的母牛所生的小牛中未出现感染（p = 0.675）。
