In recent years, mycoplasma taxonomists have found that numerous mycoplasma strains from goats are serologically indistinguishable from Mycoplasma mycoides subsp. mycoides, the causative agent of contagious bovine pleuropneumonia (CBPP), by routinely used tests, e.g. the metabolism- and growth-inhibition tests. As a result, such organisms are now openly referred to as M. mycoides subsp. mycoides. Seven of these so-called M. mycoides subsp. mycoides strains from goats were compared with two strains of M. mycoides subsp. mycoides from CBPP, and with one strain of M. mycoides subsp. capri, by means of two in-vivo tests, namely, (1) a test of the ability of each strain, injected intraperitoneally into mice, to produce mycoplasmaemia, and (2) a cross-protection test in mice. Of the seven strains, only one ('O goat') was indistinguishable from genuine M. mycoides subsp. mycoides; it also had small colonies resembling those of genuine M. mycoides subsp. mycoides. The other six were easily distinguished from genuine M. mycoides subsp. mycoides, and they produced large colonies. These six strains and others like them should no longer be given a name that fails to distinguish them from the causative agent of CBPP. Cross-protection tests showed that the seven goat strains referred to above differed from M. mycoides subsp. capri.
近年来，支原体分类学家发现，通过常规使用的试验，例如代谢和生长抑制试验，来自山羊的许多支原体菌株在血清学上与丝状支原体丝状亚种无法区分，丝状支原体丝状亚种是传染性牛胸膜肺炎（CBPP）的病原体。因此，这类生物体现在被公开称为丝状支原体丝状亚种。通过两种体内试验，即（1）将每种菌株腹腔注射到小鼠体内产生支原体血症的能力试验，以及（2）小鼠体内交叉保护试验，对来自山羊的7株所谓丝状支原体丝状亚种菌株与来自CBPP的2株丝状支原体丝状亚种菌株以及1株丝状支原体山羊亚种菌株进行了比较。在这7株菌株中，只有1株（“O山羊”）与真正的丝状支原体丝状亚种无法区分；它也有类似于真正丝状支原体丝状亚种的小菌落。其他6株很容易与真正的丝状支原体丝状亚种区分开来，并且它们产生大菌落。这6株菌株以及其他类似菌株不应再被赋予一个无法将它们与CBPP病原体区分开来的名称。交叉保护试验表明，上述7株山羊菌株与丝状支原体山羊亚种不同。
