The primary purpose of these experiments was to evaluate an autogenous Moraxella bovis bacterin administered through 2 separate routes of inoculation. An autogenous bacterin was manufactured by using M. bovis recovered from the herd. The bacterin was administered by subcutaneous injection or subconjunctival injection. In each experiment, unvaccinated animals served as controls. Random selection methods were used to place calves into a vaccination or control group. There was no statistical difference in development of infectious keratoconjunctivitis between the vaccinated and unvaccinated calves. There was a statistically significant difference between the sexes; heifers had a higher rate of keratoconjunctivitis.
这些实验的主要目的是评估通过两种不同接种途径施用的自体牛莫拉菌菌苗。自体菌苗是利用从牛群中分离出的牛莫拉菌制备的。菌苗通过皮下注射或结膜下注射施用。在每个实验中，未接种疫苗的动物作为对照。采用随机选择方法将犊牛分为疫苗接种组或对照组。接种疫苗和未接种疫苗的犊牛在感染性角膜结膜炎的发病情况上没有统计学差异。不同性别之间存在统计学显著差异；小母牛患角膜结膜炎的比率更高。
