The isolation strains 1092 of the Neisseria were separated from 10 children and 10 adults at the very early of the dental plaque. Biological, biochemical and serological experiments were undertaken on 400 colonies of the Neisseria. In addition, the tests on the glass tube wall adhesive and teeth adhesive were done to the Neisseria sicca and Neisseria mucosa. The following results were obtained. 1. The 1092 isolation strains were gram-negative, catalase-positive and oxidaseactivities Neisseria. 2. The isolation strains of the Neisseria indicated the 618 in children, the 418 in adults, respectively. Thus, the children had 1.3 times as much isolation strains of the adults. 3. The results of the pigment product test for the 400 strains examined were the 170 of the positive (42.5%) and the 230 of the negative (57.5%). 4. According to the saccharide resolution test, the 400 strains of the pigment product test showed the 150 of N. mucosa (37.5%), the 122 of N.sicca (30.5%), the 64 of N.subflave (16%), the 27 of N.flavescens (6.7%) and the 37 (9.3%), which did not belong to the others. 5. The serological results coincided with those of the saccharide resolution strains. 6. The serological classification of the 37 strains which did not belong to the others was the 16 N.sicca, the 13 N.mucosa and the 8 N.subflave, respectively. 7. Both of N. sicca and N. mucosa had the same characteristic of colony form adhesive to glucose, maltose and lactose. They also indicated iodostarch reaction. 8. The Neisseria showed more strong adhesivity to fluctose and glucose than sucrose, and indicated iodostarch reaction. 9. Thus, the evidence was gathered to prove that the Neisseria in the oral cavity took a significant and indispensable part of the very early stage in the dental plaque forming.
