Six laboratory experiments were designed to determine whether poults infected with the nonpathogenic Bordetella avium-like (BAL) bacteria would develop immunity to B. avium (BA), the causative agent of turkey coryza. The BAL bacteria were isolated from poults given that organism, but few colonies were observed by 3 weeks postexposure. No serum-agglutinating antibody to the BAL bacterium was detected in poults exposed to that organism. Poults exposed to BAL bacteria either once or twice at different ages were not protected from infection or disease following experimental challenge between 1 and 7 weeks of age with pathogenic BA.
设计了六项实验室实验，以确定感染非致病性类鸟博德特氏菌（BAL）的雏火鸡是否会对引起火鸡鼻炎的鸟博德特氏菌（BA）产生免疫力。BAL细菌是从接种该菌的雏火鸡中分离出来的，但在接触后3周观察到的菌落很少。在接触该菌的雏火鸡中未检测到针对BAL细菌的血清凝集抗体。在1至7周龄期间用致病性BA进行实验性攻毒后，不同年龄时接触过一次或两次BAL细菌的雏火鸡未受到感染或疾病的保护。
