The rats, fed a high sucrose diet, were mono-infected with seven strains of Streptococcus oralis. Moderate levels of caries were induced by four strains, and three others induced low levels. Approximal lesions were induced by two strains; no buccal/lingual lesions were produced. Scanning electron microscopy showed that all strains colonized the tooth fissures, some strains producing a moderately abundant and dense plaque. The most cariogenic strains (PB178, PB180 and PB186) induced similar levels of caries to Streptococcus milleri.
给大鼠喂食高蔗糖饮食，使其单感染7株口腔链球菌。4株诱导出中度龋齿，另外3株诱导出低度龋齿。2株诱导出邻面损害；未产生颊/舌面损害。扫描电子显微镜显示，所有菌株均在牙裂定植，一些菌株产生中度丰富且致密的菌斑。最具致龋性的菌株（PB178、PB180和PB186）诱导出的龋齿水平与米勒链球菌相似。
