Abstract

Forty-six Streptococci were isolated from human dental plaque. Each isolated from a different person, and their morphological and physiological characteristics investigated. It was found that the isolated micro-organisms 1. Most found that the isolated micro-organisms 2. Acid produced from maltose, inulin, manitol, sorbitol, lactose, mannose, 3. In the sucrose broth, most of them formed gelatinous clusters adhearing to the wall of the tube.

충치 sample 50개에서 46 strains의 Streptococcus sp.를 분리하여 그 생리적 특징을 조사한 바 1. 대부분의 균주들이 non-haemolytic strain이었으며, 2. 기질로 maltose, inulin, mannitol, sorbisI, lactose, mannabinose를 분해하여 산을 생성하고 arabinose와 xylose는 균주에 따라 차이를 보였으며, 3. Sucrose broth에서는 거의 gel을 형성하였다.
