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.

Method of vaccination for prevention of Bordetella bronchiseptica

Nasal nozzle

Method and means for vaccinating a mammal using a convex nozzle with an elongated tip. The mammal's alar fold is pushed aside by the tip so that vaccine is deposited behind the alar fold. Vaccine is then dispensed through the nozzle.

A combination vaccine for increasing the resistance of swine to dysentery infection comprises killed cells of a virulent isolate of Treponema hyodysenteriae in combination with concentrated killed cells of Bacteroides vulgatus, or Fusobacterium necrophorum, or mixtures thereof. This combination vaccine can be adapted for either oral or parenteral administration. For parenteral administration preferably only Bacteroides vulgatus is used in combination with Treponema hyodysenteriae. The oral vaccine is enteric-coated.

Combination vaccine for swine dysentery and method of use

The resistance of field-raised swine to dysentery infection is increased by a sequence of parenteral and oral administrations. First there is parenterally administered to the swine an injectable cell concentrate containing a virulent isolate of killed cells of Treponema hyodysenteriae, and not less than five days after the animals have received the first of the parenteral injections, a series of oral administrations of enteric-coated pellets is started, the pellets containing concentrated killed cells of a virulent isolate of T. hyodysenteriae. The oral administrations are given at least once every 24 hours for a period of at least five days.

Method of increasing the effectiveness of oral vaccination for swine

An oral preparation for increasing the resistance of swine to swine dysentery infection comprises enteric-coated orally-administrable pellets containing concentrated killed cells of a virulent isolate of Treponema hyodysenteriae. In the preferred method of use, the preparation is orally administered to swine in a plurality of doses providing at least 3 mg. of the cells per animal per dose.
