猪支原体与新鲜动物血清的相互作用。

J Hyg (Lond). 1971 Sep;69(3):361-8. doi: 10.1017/s0022172400021604.

When fresh animal serum was dropped onto seeded mycoplasma agar plates, inhibition of growth frequently occurred. This effect was dependent on the mycoplasma serotype and on the animal species from which the fresh serum came. This activity of fresh animal serum was heat-labile and would not diffuse through the agar medium. Growth of all the porcine mycoplasma serotypes was inhibited by fresh sheep serum. M. hyorhinis, M. hyopneumoniae, B 3 and the P 45 strains were insensitive to fresh horse serum. The addition of fresh horse serum to specific M. hyorhinis rabbit antiserum-impregnated disks appeared to have a synergistic effect and the combination of M. hyorhinis antiserum-impregnated disk and fresh horse serum always inhibited the growth of M. hyorhinis strains.

当将新鲜动物血清滴加到接种了支原体的琼脂平板上时，经常会出现生长抑制现象。这种效应取决于支原体血清型以及新鲜血清所来自的动物物种。新鲜动物血清的这种活性对热不稳定，且不会扩散穿过琼脂培养基。所有猪支原体血清型的生长都受到新鲜绵羊血清的抑制。猪鼻支原体、猪肺炎支原体、B3和P45菌株对新鲜马血清不敏感。向特定的猪鼻支原体兔抗血清浸渍圆片中添加新鲜马血清似乎具有协同作用，并且猪鼻支原体抗血清浸渍圆片与新鲜马血清的组合总能抑制猪鼻支原体菌株的生长。
