链球菌属

方法：经初步鉴定健康青少年口腔优势菌为血链球菌属后，用随机引物AP-PCR对优势菌进行扩增、检测。

Methods : After predominant bacteria in oral cavity of healthy adolescent was identified primarily to Streptococcus .

结论PCR-DGGE技术结合rnpB基因克隆文库分析可较灵敏、直观地反映牙菌斑中链球菌属各菌群及其菌种的组成情况。

Conclusion PCR-DGGE method combined with rnp B clone library profiling is a sensitive and effective approach to resolve the population structure of oral Streptococci in microflora of dental plaque .

乙酸的累积主要是消化链球菌属通过氨基酸之间的Stickland反应形成的。

Peptostreptococcus played an main role on the accumulation of acetic acid . The main metabolic pathway for producing acetic acid was the Stickland reaction between different amino acids .

G+阳性菌株占22.90%，顺位依次为：葡萄球菌属、肠球菌属、肺炎链球菌属。

22.90 % was G + bacteria the descending order was : staphylococcus , Enterobacter and pneumococcus .

共分离出69株菌株，其中肠杆菌科细菌30株，肠球菌属细菌19株，其余为葡萄球菌属细菌、链球菌属细菌等。

69 strains of bacteria were detected including 30 strains of Enterobacteriaceae , 19 strains of Enterococcus and others including Staphylococcus , Streptococcus etc.
