Technical Abstract: Poults passively immunized and not passively immunized against Bordetella avium were exposed to live B. avium at 2-days old. Birds not passively immunized developed severe coryza with early onset, whereas passively immunized birds developed mild coryza with late onset. Following convalescence, birds with and without exposure to B. avium were vaccinated against fowl cholera using water-in-oil bacterin and challenged with serotype A:3 Pasteurella multocida. No differences in protection against fowl cholera were seen between vaccinated turkeys previously infected with B. avium and those which were not; survivability was better when 2 doses, rather than 1 dose, of bacterin were given.
