Lack of protection against Bordetella avium in turkey poults exposed to B. avium-like bacteria.
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.
