| 摘要 |
<p>The invention provides DNA sequences which code for polypeptides which are characteristic for the virulence of the pathogenic bacterium Streptococcus suis and parts thereof, and polypeptides and antibodies derived therefrom. The sequences code for a polypeptide of 90.000-120.000 daltons or a polypeptide of higher molecular weight containing such a polypeptide, and for a polypeptide of 135.000-136.000 daltons (muramidase released protein), or parts thereof. The sequences themselves, and also the polypeptides and antibodies derived therefrom, are used for diagnosis of and protection against infection by S. suis in mammals, including man.</p> |
