    • The present invention provides methods for inducing cross-protective immunity against virulent strains of P. multocida in animals such as cattle and poultry. The methods of the invention include administering to an animal a mutant P. multocida strain, whereby the mutant P. multocida strain induces cross-protective immunity against one or more virulent P. multocida strains having serotypes that are different from the serotype of the mutant P. multocida strain. The mutant P. multocida strain will preferably contain one or more mutations that cause the cells to be acapsular and/or attenuated. Exemplary mutations include, e.g., mutations that impair the expression of one or more genes in the P. multocida capsule biosynthetic operon (e.g., phyB, phyA, hyaE, hyaD, hyaC, hyaB, hexD, hexC, hexB, and/or hexA).
    • 本发明提供了在动物如牛和家禽中诱导针对多杀巴斯德氏体毒性毒株的交叉保护性免疫的方法。 本发明的方法包括对动物施用突变体多杀巴斯氏杆菌菌株,其中突变体多杀巴斯德氏杆菌菌株对具有不同于突变体P的血清型的血清型的一种或多种毒力多杀巴氏杆菌菌株诱导交叉保护性免疫 多毛菌株。 突变体多杀巴斯德氏菌菌株将优选含有一种或多种导致细胞被囊泡和/或减毒的突变。 示例性的突变包括例如损害多球梭菌(Multocida)胶囊生物合成操纵子中一个或多个基因表达的突变(例如phyB,phyA,hyaE,hyaD,hyaC,hyaB,hexD,hexC,hexB和/或hexA) 。

    • The present invention provides live, attenuated Mycoplasma gallisepticum bacteria that exhibit reduced expression of a protein identified as MGA_0621. In certain embodiments, the attenuated bacteria may additionally exhibit reduced expression of one or more proteins selected from the group consisting of pyruvate dehydrogenase, phosphopyruvate hydratase, 2-deoxyribose-5-phosphate aldolase, and ribosomal protein L35, relative to a wild-type M. gallisepticum bacterium. Also provided are vaccines and vaccination methods involving the use of the live, attenuated M. gallisepticum bacteria, and methods for making live attenuated M. gallisepticum bacteria. An exemplary live, attenuated strain of M. gallisepticum is provided, designated MGx+47, which was shown by proteomics analysis to exhibit significantly reduced expression of MGA_0621, and was shown to be safe and effective when administered as a vaccine against M. gallisepticum infection in chickens.
    • 本发明提供活的,减毒的鸡毒支原体细菌,其表现出被鉴定为MGA_0621的蛋白质的表达降低。 在某些实施方案中,相对于野生型M,减毒细菌可另外显示出一种或多种选自丙酮酸脱氢酶,磷酸丙酮酸水合酶,2-脱氧核糖-5-磷酸醛缩酶和核糖体蛋白L35的蛋白质​​的表达降低 胆汁败霉菌 还提供了涉及使用活的,减毒的金黄色葡萄球菌细菌的疫苗和疫苗接种方法,以及用于制造活的减毒的金黄色葡萄球菌细菌的方法。 提供了一种示例性的活的减毒毒株的菌株,命名为MGx + 47,通过蛋白质组学分析显示出显着降低的MGA_0621的表达,并且当作为针对鸡链球菌毒素感染的疫苗施用时被证明是安全和有效的 在鸡中
