Evidence that cattle, goats and rabbits may suffer from natural diseases equivalent to porcine atrophic rhinitis is presented. Etiology and course of the progressive (enzootic) and non-progressive (sporadic) forms of atrophic rhinitis in pigs are discussed and compared with known data about similar diseases in other animals. It seems that atrophic rhinitis caused by toxigenic strains of Pasteurella multocida may be a disease of different animal species.
