    • The use of the 17 kDa outer surface lipoprotein (OspA) of Piscirickettsia salmonis, or its homologues, as the basis of, or part thereof, a recombinant vaccine for salmonid rickettsial septicaemia and other rickettsial diseases is disclosed. Surface antigens of the bacterial pathogen P. salmonis are characterized and an immunoreactive antigen, namely the 17 kDa outer surface lipoprotein OspA of P. salmonis, as well as the nucleic acid segment that encodes the OspA immunoreactive antigen, is identified and characterized. Diagnostic techniques including the use of hybridization probes and primers as well as the production of specific antigens and antibodies that may be used in immunization techniques for inducing immunity against P. salmonis and other rickettsial diseases are disclosed, as are the development of recombinant vaccines for SRS and other rickettsial diseases based on the 17 kDa lipoprotein OspA. Augmentation of protective immunity by the inclusion of promiscuous T lymphocyte epitopes (TCE's) in fusion protein constructs in salmonids and to the use of bacterial protein inclusion bodies as a source of the protective immunogen is also disclosed.
    • 公开了使用沙门氏菌属的17kDa外表面脂蛋白(OspA)或其同系物作为鲑鱼样立克次体败血症和其他立克次体疾病的基础或其一部分的重组疫苗。 表征细菌病原体沙门氏菌的表面抗原,并鉴定和表征免疫反应性抗原,即沙门氏菌的17kDa外表面脂蛋白OspA以及编码OspA免疫反应性抗原的核酸片段。 公开了包括使用杂交探针和引物的诊断技术以及可用于诱导针对鲑鱼和其他立克次体疾病的免疫的免疫技术中的特异性抗原和抗体的产生,以及用于SRS的重组疫苗的开发 和基于17kDa脂蛋白OspA的其他立克次体疾病。 还公开了通过在混合型T淋巴细胞表位(TCE)中包含鲑鱼中的融合蛋白构建体和使用细菌蛋白包涵体作为保护性免疫原来源来增强保护性免疫。
