The immune responses of the turkey and fowl to intra-rectal infections with tissue containing were studied. A protective immunity was produced in drug-treated turkeys and in fowls recovering spontaneously. These birds develop precipitating antibodies in their sera to an antigen derived from . Antigen was first detected in caecal contents 4 days after infection and serum precipitins 7 days later. It was not possible to transfer protective immunity by injections of serum from immune to susceptible birds.
研究了火鸡和家禽对含有……的组织进行直肠内感染的免疫反应。在经药物治疗的火鸡和自发恢复的家禽中产生了保护性免疫。这些禽类血清中产生了针对源自……的抗原的沉淀抗体。感染后4天在盲肠内容物中首次检测到抗原,7天后检测到血清沉淀素。不可能通过将免疫禽类的血清注射到易感禽类来转移保护性免疫。
