Abstract
Abstract 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.

An oral preparation for increasing the resistance of swine to dysentery infection, comprising enteric-coated orally-administrable pellets containing concentrated killed cells of a virulent isolate of Treponema hyodysenteriae in combination with concentrated killed cells of other bacteria selected from the group consisting of Bacteroides vulgatus, Fusobacterium necrophorum, and mixtures thereof, at least one of said other bacteria being present in an amount of from 0.25 to 2 parts by weight (dry basis) per part of said Treponema hyodysenteriae.
Claim 2
Dependent Claim
77 words
An oral preparation for increasing the resistance of swine to dysentery infection, comprising enteric-coated orally-administrable pellets containing concentrated killed cells of a virulent isolate of Treponema hyodysenteriae in combination with concentrated killed cells of other bacteria selected from the group consisting of Bacteroides vulgatus, Fusobacterium necrophorum, and mixtures thereof, at least one of said other bacteria being present in an amount of from 0.25 to 2 parts by weight (dry basis) per part of said Treponema hyodysenteriae.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
14 words
The oral preparation of claim 1 in which said other bacteria is Fusobacterium necrophorum.
Claim 5
Dependent Claim
42 words
The oral preparation of claim 1 in which said other bacteria comprises both said Bacteroides vulgatus and Fusobacterium necrophorum, and each are present in an amount of from 0.25 to 2 parts by weight (dry basis) per part of said Treponema hyodysenteriae.
Claim 6
Dependent Claim
35 words
The oral preparation of claim 1 in which each of said other bacteria that is present are present in an amount of 0.5 to 1.5 parts by weight (dry basis) per part of Treponema hyodysenteriae.
Claim 7
Independent Claim
95 words
The method of increasing the resistance of field-raised swine to dysentery infection, comprising orally administering to the swine prior to their contracting the infection a plurality of doses of enteric-coated pellets containing concentrated killed cells of Treponema hyodysenteriae in combination with concentrated killed cells of other bacteria selected from the group consisting of Bacteroides vulgatus, Fusobacterium necrophorum, and mixtures thereof, each of said doses providing at least 3 milligrams (dry basis) of said Treponema hyodysenteriae cells together with from 0.25 to 2 parts by weight (dry basis) of at least one of said other bacteria.
Claim 8
Independent Claim
95 words
