Few experiments have been reported on immunity to reinfection in domestic stock. The degree of resistance to reinfection with S. mattheei was studied in cattle and sheep. On the basis of the results, the only evidence of acquired immunity in calves and sheep is a reduction in the length of adult worms.
关于家畜再次感染的免疫力,所报道的实验很少。研究了牛和羊对马氏无卵黄腺绦虫再次感染的抵抗程度。根据研究结果,犊牛和绵羊获得性免疫的唯一证据是成虫长度缩短。
