Abstract
Viable cells of an avirulent self-clearing strain of B. bronchiseptica are administered as an intra-respiratory vaccine. An aqueous suspension of the cells is applied to the respiratory mucosa immediately after incorporating a non-inhibitory amount of a wetting agent promoting the mucosal implantation of the cells. Effective immunization can thereby be obtained against diseases such as kennel cough in dogs and atrophic rhinitis in swine even through the strain of B. bronchiseptica is so highly attenuated that it is self-clearing from the respiratory mucosa.
