[The inhibitory effect of anti-streptococcus mutans immunoglobulin of yolk on glucan synthesis of Streptococcus mutans].

ABSTRACT

OBJECTIVES: To observe the inhibitory effect of anti-Streptococcus mutans Hen-egg-yolk (IgY) on glucan synthesis of Streptococcus mutans. METHODS: Determine the glucan with anthrone method after using the different titer of IgY on S.mutans and S.sobrinus. RESULTS: The inhibitory effect of antibody on S.mutans and S.sobrinus synthesis glucan had a similar tendency. The effect of inhibit glucan synthesis was influenced by the titer of antibody. High titer with high inhibition. Begin with the group of 116 titer, the group of 12 titer showed the highest inhibition (P<0.05). CONCLUSION: The antibody can reduce synthesis of glucan from S.mutans and S.sobrinus.
