抗变形链球菌卵黄免疫球蛋白

Specific egg yolk immunoglobulin of anti Streptococcus mutans

龋病是一种细菌感染引起的疾病。变形链球菌被证明是最主要的致龋菌。用被动免疫方法来预防龋齿是一种可能的途径 ,蛋鸡是产生特异性抗体的一个很好的来源。在免疫后特异性抗体能转移到蛋黄中 ,在提纯后 ,一只鸡蛋黄可提取约 15 0mg的抗体。鸡蛋作为一种日常的食品 ,没有产生毒副作用的危险 。

Dental caries is a disease caused by microbial pathogens, including Streptococcus mutans ,which is the principal etiologic agent. Passive immunization is a feasible approach against dental caries.
