    • The present invention relates to recombinant DNA molecules which encode bovine respiratory syncytial (BRS) virus proteins, to BRS virus proteins, and peptides and to recombinant BRS virus vaccines produced therefrom. It is based, in part, on the cloning of substantially full length cDNAs which encode the entire BRS virus G, F, and N proteins. According to particular embodiments of the invention, DNA encoding a BRS virus protein or peptide may be used to diagnose BRS virus infection, or, alternatively, may be inserted into an expression vector, including, but not limited to, vaccinia virus as well as bacterial, yeast, insect, or other vertebrate vectors. These expression vectors may be utilized to produce the BRS virus protein or peptide in quantity; the resulting substantially pure viral peptide or protein may be incorporated into subunit vaccine formulations or may be used to generate monoclonal or polyclonal antibodies which may be utilized in diagnosis of BRS virus infection or passive immunization. In additional embodiments, BRS virus protein sequence provided by the invention may be used to produce synthetic peptides or proteins which may be utilized in subunit vaccines, or polyclonal or monoclonal antibody production. Alternatively, a nonpathogenic expression vector containing the genes, parts of the genes, any combination of the genes, or parts thereof may itself be utilized as a recombinant virus vaccine.
    • 本发明涉及编码牛呼吸道合胞体(BRS)病毒蛋白质,BRS病毒蛋白质的重组DNA分子,以及由其产生的重组BRS病毒疫苗。 其部分基于克隆编码整个BRS病毒G,F和N蛋白的基本上全长的cDNA。 根据本发明的具体实施方案,编码BRS病毒蛋白或肽的DNA可用于诊断BRS病毒感染,或者可以将其插入到表达载体中,包括但不限于痘苗病毒以及细菌 ,酵母,昆虫或其他脊椎动物载体。 这些表达载体可以用来量产BRS病毒蛋白或肽; 所得到的基本上纯的病毒肽或蛋白质可以并入亚单位疫苗制剂中,或可用于产生可用于诊断BRS病毒感染或被动免疫的单克隆或多克隆抗体。 在另外的实施方案中,本发明提供的BRS病毒蛋白质序列可用于产生可用于亚单位疫苗或多克隆或单克隆抗体产生的合成肽或蛋白质。 或者,含有基因,部分基因,基因的任何组合或其部分的非致病性表达载体本身可以用作重组病毒疫苗。
