Seventy-three cases of the thymic form of leukosis were found in Holstein calves in five departments of France over a period of five months. Most of the calves had been sired by the same bull. The calves were negative for specific antibodies to bovine leukaemia virus. Morphological studies including light and electron-microscopic cytology, and serological and virological studies of 14 of the cases suggest that the disease was transmitted genetically.
在五个月的时间里，法国五个部门的荷斯坦小牛中发现了73例胸腺型白血病病例。大多数小牛是同一头公牛的后代。这些小牛对牛白血病病毒的特异性抗体呈阴性。对其中14例病例进行的形态学研究，包括光镜和电镜细胞学检查，以及血清学和病毒学研究表明，该病是通过遗传方式传播的。
