| Abstract |
|
This report was concerned with the isolation and identification of bacterial flora in the human dental plaque and the dextransucrase activity of isolated species. The results were obtained as follows: 1. The bacterial flora, isolated from the human dental plaque, was identified as 3 species of resembling streptococci, Streptococcus salivarius strain SD-1, Streptococcus bacilli, Lactobacillus brevis strain SD-3, Lactobacillus acidophilus strain SD-2 and SD-7, resembling Staphylococcus sp, and one species of resembling Leuconostoc mesenteroides strain SD-6. 2. The dextransucrase activites of resembling Streptococcus mitis strain SD-9 and Streptococcus salivarius strain SD-1 were exhibited the highest among the isolated species of human dental plaque. |
