The virulence of three strains of Mycoplasma gallisepticum (S6 of low broth passage, S6 of high broth passage and A514) and of one strain of M gallinarum was investigated in specific pathogen free chicks, turkey poults, chick embryo tracheal organ cultures and embryonated fowl eggs. One strain of M gallisepticum, S6, of low passage, caused high mortality in newly hatched chicks, and turkey poults, high embryo mortality, and rapid suppression of ciliary activity in tracheal organ cultures. The other strains of M gallisepticum and M gallinarum had relatively less effect. In view of its greater sensitivity, chick embryo mortality is preferable to tracheal organ culture for assessing the virulence of experimental strains of M gallisepticum.
在无特定病原体的雏鸡、小火鸡、鸡胚气管器官培养物和鸡胚中，研究了三株鸡毒支原体（低肉汤传代的S6、高肉汤传代的S6和A514）以及一株鸡支原体的毒力。一株低传代的鸡毒支原体S6在新孵出的雏鸡和小火鸡中引起高死亡率、高胚胎死亡率，并能快速抑制气管器官培养物中的纤毛活性。其他鸡毒支原体菌株和鸡支原体菌株的影响相对较小。鉴于其更高的敏感性，在评估鸡毒支原体实验菌株的毒力时，鸡胚死亡率比气管器官培养更可取。
