Inactivated vaccine against Ornithobacterium rhinotracheale in oil emulsion

Ornithobacterium rhinotracheale is a Gram-negative, non-motile, highly pleomorphic, rod-shaped, non-sporulating bacterium, which has become an emerging pathogen that causes high economic losses in the poultry industry worldwide. Ornithobacterium rhinotracheale infection, which is reported mostly in broiler chickens and turkeys, causes respiratory distress, decreased growth, and mortality. The best strategy for their control or prevention is probably vaccination, because most worldwide O. rhinotracheale isolates have acquired resistance against the antibiotics regularly used in the poultry industry.
