[The inhibitory effect of anti-streptococcus mutans immunoglobulin of yolk on glucan synthesis of Streptococcus mutans].
OBJECTIVE
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 1:16 titer, the group of 1:2 titer showed the highest inhibition (P<0.05).


CONCLUSIONS
The antibody can reduce synthesis of glucan from S.mutans and S.sobrinus.
