The attempted immunization of 53 female Broad Breasted White turkeys with five weekly 1.0 ml injections of viable Mycoplasma meleagridis, when combined with insemination with M. meleagridis infected semen, did not produce immunity but only imposed additional infection. This was detrimental to the offspring by increasing the incidence and severity of air sac lesions.
对53只雌性宽胸白火鸡每周进行一次，每次1.0毫升的活火鸡支原体注射，共注射五次，同时用感染了火鸡支原体的精液进行授精，结果并未产生免疫力，反而增加了额外感染。这对后代有害，会增加气囊病变的发生率和严重程度。
