摘要:
The invention provides Streptococcus vaccine strains (e.g. S. equi which is causative of ‘strangles’) comprising the following modifications in their genomes: (i) attenuation of one or more essential biosynthetic genes, (ii) attenuation of one or more genes which encode a haemolytic toxin, or protein involved in the production thereof, plus preferably any one, two, or most preferably three of the following modifications: (iii) attenuation of one or more genes which encode a protein responsible for immune evasion (iv) modification of one or more genes such as to permit serological discrimination of the vaccine strain based on analysis of a protein encoded by said genes, and (v) attenuation of one or more genes which encode an enzyme responsible for recombination repair of the genome. The invention provides inter alia live attenuated vaccine strains which generate an immune response to multiple protective epitopes presented in a context resembling the live pathogen.
摘要(中):
本发明提供了链球菌疫苗菌株(例如,引起“扼杀”的马氏足疟原虫),其包含其基因组中的以下修饰:(i)减少一种或多种必需生物合成基因,(ii)减少一个或多个编码的基因 溶血素毒素或参与其生产的蛋白质,优选任何一种,两种,或最优选三种以下修饰:(iii)减少编码负责免疫逃避的蛋白质的一种或多种基因(iv) 基于对由所述基因编码的蛋白质的分析来允许对疫苗株进行血清学鉴定的一个或多个基因,以及(v)减少编码负责基因组重组修复的酶的一个或多个基因。 本发明特别提供减毒疫苗菌株,其产生对类似于活病原体的上下文中呈现的多种保护性表位的免疫应答。
