【摘要】 对我国部分地区奶牛场临床型乳房炎病乳中分离鉴定出的24株无乳链球菌、7株停乳链球菌和10株金黄色葡萄球菌,进行3种菌株之间及同种异地各菌株间血清学交叉反应试验.结果表明:无乳链球菌、停乳链球菌和金黄色葡萄球菌3种菌株之间无免疫交叉反应,但我国各地同种异地间各菌株间存在不同程度的血清学交叉反应,而且菌株之间交叉反应程度有明显差异,表明该方法可作为制苗菌株抗原性筛选的一项重要指标.更多还原

【Abstract】 Twenty-four strains of Streptococcus agalactiae,7 strains of Streptococcus dysgalactiae and 10 strains of Staphylococcus aureus were isolated and identified from cow milk samples with clinical mastitis from different regions of China.The serological cross immunology test for the three strains of pathogenic bacteria had not showed immune cross reaction,but serological cross immunology reaction occurred in different extent among the same strains from different regions,and the degree of cross reaction had significant difference among the strains.更多还原
