Vaccine against streptococci
The invention relates to subunit immunogenic or vaccine compositions which may comprise at least one polypeptide of Streptococcus equi and methods for preparing and/or formulating such compositions. The invention also relates to the use of such subunit compositions, such as a method for eliciting an immunogenic response or a protective immune response, which may comprise administering the composition to a mammal susceptible to streptococcal infection.
1. An immunogenic composition comprising at least one polypeptide comprising the amino acid sequence of SEQ ID NO: 22.
2. An immunogenic composition comprising at least one polypeptide comprising the amino acid sequence of SEQ ID NO: 36.
3. The immunogenic composition of claim 1 , wherein the immunogenic composition reduces the severity of strangles in an equine caused by Streptococcus equi infection.
4. A diagnostic kit for detecting infection by Streptococcus equi comprising at least one polypeptide of claim 1 .
