| 摘要 |
<p>The present invention provides isolated polypeptides having oligopeptide permease activity and an amino acid sequence that has at least 80 % identity with a Haemophilus parasuis OppA polypeptide. Also provided by the present invention are isolated polynucleotides that encode the polypeptides described herein, and antibody that specifically binds a polypeptide described herein. The present invention further provides genetically modified microbes, such as attenuated Haemophilus parasuis strains and other microbes that express polypeptides described herein. Also included are methods for using the polypeptides, polynucleotides, antibody, and genetically modified microbes.</p> |
