ABSTRACT:
The present invention relates to novel bacterial extract vaccines for use in veterinary medicine and to novel methods for preparing such vaccines. The bacteria responsible for a particular bacterially induced disease is contacted with a detergent so as to extract from the bacterial cells the antigens responsible for eliciting a protective immune response against the disease. Subsequently, the resultant antigen extract is dialyzed to remove the detergent. The antigen extract is then preferably combined with a vaccine enhancing adjuvant to provide an effective and inexpensive vaccine for veterinary application. The present invention provides for the preparation of a variety of vaccines which can be used to immunize animals against a variety of bacterially induced diseases.
