Characterization of Streptococci Isolated from Human Dental Plaque

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.

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.
