摘    要:为获得控制猪链球菌病安全高效的疫苗,本试验进行了马链球菌兽疫亚种类M蛋白亚单位疫苗的研制。应用热酸法提取马链球菌兽疫亚种ATCC35246株类M蛋白,并分别采用羟基磷灰石(HAT)层析和冷酒精沉淀法进行纯化,结果得到较纯的类M蛋白。用热酸提取的粗制类M蛋白、2种纯化的类M蛋白及全菌苗免疫小鼠,结果保护率分别为92%(11/12)、100%(12/12)、100%(12/12)和83%(10/12),表明类M蛋白亚单位疫苗有进一步开发的必要。

关 键 词:马链球菌兽疫亚种  类M蛋白  疫苗

Abstract:Streptococcus equi subsp.zooepidemicus,a lancifield group C Streptococcus,is an important pathogen of pigs.Previous studies have indicataed that M-like protein is an important virulence factor and protective antigen.We extracted the M-protein by hot-acid ways,and the acid-extracted proteins were partially purified by hydroxyapatite(HAT) chromatography and cold-alcohol precipitate.The whole cell bacterin,the acid-extracted protein and partially purified M-like protein were applied to vaccinate mice with the protective efficacy of 83.3%(10/12),92%(11/12),100%(12/12) respectively.It suggested that the M-like protein vaccine against Streptococcus equi subsp.zooepidemicus would be necessary for to be further developed.
Keywords:Streptococcus equi  M-like protein  vaccine
