POLYNUCLEOTIDES OF HAEMOPHILUS PARASUIS AND ITS USE

摘要

The present invention relates to Haemophilus parasuis polynucleotides produced by recombinant technology. It also relates to polypeptides that are expressed by said polynucleotides and also to a vaccine against H.parasuis that comprises said polypeptides. In another aspect, the invention also relates to the use of polynucleotides to determine if a strain of H. parasuis is virulent or avirulent.
