中文摘要
目的观测3种口腔链球菌对白假丝酵母菌的生长有无抑制作用。方法采用直接点种法、反点种菌落计数法和液体共培养法观测口腔变异链球菌、血链球菌、唾液链球菌对白假丝酵母菌的拮抗作用。结果1）直接点种法中各组均未观察到清晰的抑菌圈；2）唾液链球菌软琼脂上的白假丝酵母菌菌落数较对照组减少（P0.05）。结论3种口腔链球菌对白假丝酵母菌的体外生长有明显抑制作用，但尚不能确定哪种链球菌的抑制作用更强，并且抑制作用会逐渐衰减。
英文摘要
Objective To investigate the antagonistic effects of three species of oral Streptococcus on the growth of oral Saccharomyces albicans in vitro. Methods Direct inoculation method, reverse inoculation method and mixed culture methods were respectively chosen to observe the changes of Saccharomyces albicans colony formation on the effects of Streptococcus mutans, Streptococcus sanguis and Streptococcus salivarius. Results 1）No clear inhibition zone was observed in each of the groups by direct inoculation method. 2）Compared with the control groups, Saccharomyces albicans colony formation on soft agar of Streptococcus sanguis decreased significantly（P0.05）. Conclusion treptococcus mutans, Streptococcus sanguis, and Streptococcus salivarius could obviously inhibit the growth of Saccharomyces albicans in vitro. However, it is still unclear that among which the inhibition effects is stronger. The antagonistic effects is weakened gradually.
