The relative virulence of various strains of Moraxella bovis (M. bovis) was studied using the eyes of mice and cattle. The investigation consisted of three separate experiments. Experiments I and II involved a study on the effects of (1) different methods of growth and (2) serial blood agar passaging on the virulence of M. bovis. Experiment III involved a study on the relative virulence of different strains of M. bovis and M. bovis-like organisms. Strains of M. bovis and M. bovis-like organisms varied in their pathogenicity for mice. However, different methods for preparation of exposure cultures of M. bovis did not influence the disease produced.
利用小鼠和牛的眼睛研究了不同牛莫拉菌（M. bovis）菌株的相对毒力。该研究由三个独立实验组成。实验I和II涉及对（1）不同生长方法和（2）连续血琼脂传代对牛莫拉菌毒力影响的研究。实验III涉及对不同牛莫拉菌菌株和类牛莫拉菌生物相对毒力的研究。牛莫拉菌菌株和类牛莫拉菌生物对小鼠的致病性各不相同。然而，制备牛莫拉菌暴露培养物的不同方法并未影响所产生的疾病。
