  • polypeptides and polynucleotides encoding same and their use in vaccinal and diagnostic applications
    Patent number: 7927608
    Abstract: The present invention relates to the field of Streptococcus. More specifically, the present invention relates to the identification of polypeptides and polynucleotide sequences encoding the same which are involved in the pathogenic mechanism of S. suis. The present invention also relates to the use of such polypeptides in compositions and methods for the prevention, the treatment and diagnosis of S. suis-associated diseases and infections caused by S. suis.
