Development of immunity to reinfection with Mycoplasma dispar occurred in the bovine mammary gland and appeared to be confined to the quarter or quarters previously infected with this mycoplasma; it was not generalized throughout the gland. Immunity followed the inoculation of virulent strains of M. dispar but not of an avirulent strain. The immunity engendered protected against both homologous and heterologous strains of M. dispar. Challenge of immune quarters with virulent M. dispar resulted in a transient polymorphonuclear cell response greater than that observed in previously uninoculated quarters.
牛乳腺中出现了对再次感染支原体的免疫力,且这种免疫力似乎局限于先前感染过这种支原体的一个或多个乳腺小叶;并非在整个乳腺中普遍存在。接种毒力强的支原体菌株后会产生免疫力,但接种无毒力菌株则不会。所产生的免疫力可抵御同源和异源的支原体菌株。用毒力强的支原体攻击免疫过的乳腺小叶,会引发比先前未接种过的乳腺小叶中观察到的更强烈的短暂多形核细胞反应。
