1·Positive blood culture was found in 71 patients (57.7%) of viridans streptococci (32.4%), staphylococcus epidermidis (15.5%).
血培养阳性率为57.7％，其中主要致病菌是草绿色链球菌（32.4％）和表皮葡萄球菌（15.5％）。
2·Mutans streptococci (MS) are the primary cariogenic agents, and Streptococcus mutans and Streptococcus sobrinus are believed to have the closest relationship with human caries.
变形链球菌族（MS）是目前公认的致龋菌，其中与人类龋病发生关系密切的是变形链球菌和茸毛链球菌。
3·Antibiotic selection also should cover group B streptococci and enteric rod organisms in neonates.
同时也应该覆盖乙型链球菌以及新生儿期大肠杆菌。
4·In many cases, these organisms are streptococci or staphylococci bacteria.
在许多情况下，这些生物体是链球菌或葡萄球菌等病菌。
5·The results showed that sucrose was the only substrate of these two streptococci and there was no significant difference in their amount of synthesizing glucan from sucrose.
结果显示两种变形链球菌只能利用蔗糖合成葡聚糖，且合成葡聚糖总体能力相似。
