Abstract
The inhibition degree of the isolated bacteria on plaque formation of Streptococcus mutans, and the effect of these bacterial genus on the concentration of total bacteria in saliva were assessed with the following. The effectiveness of the isolated bacteria on the inhibition of plaque formation was assessed culturing Streptococcus mutans in the beaker with orthodontic wires. The mean weight of plaque produced on a wire was 152mg in the culture of Streptococcus mutans only, whereas being reduced to 4mg, 78mg, or 72mg in the combined culture of Streptococcus mutans and Enterococcus durans, Lactobacillus acidophilus, or Streptococcus oralis. The colony forming units (CFU) of Streptococcus mutans were
소아의 구강으로부터 분리한 비수용성 글루캔 형성 억제세균의 Streptococcus mutans 치태 형성에 대한 억제 정도와 분리 세균속의 타액내 농도가 타액내 전체 세균의 농도에 미치는 영향을 본 결과 다음과 같은 결과를 얻었다. 구강으로부터 분리한 비수용성 글루캔 형성 억제세균의 효과를 비커 와이어 검사로 본 결과, 교정용 와이어상에 형성된 치태의 무게가 Streptococcus mutans 단독배양시 152mg에서 Enterococcus durans, Lactobacillus acidophilus, Streptococcus oralis와의 혼합배양시 각각 4mg, 78mg, 72mg으로 감소되었다. Streptococcus mutans의 생균수는 단독배양시 ml당
