Streptomycin-dependent Escherichia coli serotypes O 111, O 55 and O 26 were used to vaccinate young patas monkeys against these organisms by the oral route. Five administrations of 10(10) cells in 3-day intervals gave almost full protection to the animals against challenge with 9 to 11 minimal infective doses of homologous virulent organisms for at least 1 month, whether the three serotypes were administered singly or simultaneously.
利用对链霉素依赖的大肠杆菌血清型O 111、O 55和O 26,通过口服途径对幼小的粗尾猿猴进行针对这些微生物的疫苗接种。以3天的间隔给予5次每次10¹⁰个细胞的剂量,无论这三种血清型是单独给药还是同时给药,都能使动物几乎完全免受9至11个最小感染剂量的同源有毒微生物的攻击,保护期至少为1个月。
