The results of oral vaccination of 388 calves with herd-specific vaccines against E. coli are described. Innocuity was optimal, whereas the potency was estimated not as efficient as parenteral vaccination of the dam (in 22% of the cases), i.e., transient diseases in vaccinated calves occurred there. Further the results of intranasal vaccination of 496 cattle against salmonellosis are reported. Salmonella excretion in the faeces was stopped within 1-3 weeks post vaccination in 75% of the herds. In one case it took 3 months to reach this effect. A few permanent excretor cattle remained in two other cases.
描述了用针对大肠杆菌的群体特异性疫苗对388头小牛进行口服接种的结果。安全性最佳,但效力估计不如对母牛进行的非肠道接种有效(在22%的病例中),即接种疫苗的小牛出现了短暂疾病。此外,报告了对496头牛进行鼻内接种预防沙门氏菌病的结果。在接种疫苗后1至3周内,75%的牛群粪便中的沙门氏菌排泄停止。在一个案例中,达到这种效果用了3个月。在另外两个案例中,有几头持续排泄的牛。
