本研究自人牙菌斑内成功地分离出小韦永氏球菌,将它与变形链球菌、血链球菌、唾液链球菌、干酪乳杆菌、粘性放线菌分别或混合一齐培养,结果使这些致龋菌培养液的pH值上升(唾液链球菌除外),培养液内的乳酸含量大为减少,乙酸、丙酸含量增多。 This study successfully isolated from human plaque Dermatoveneces microveschiensis, it and Streptococcus mutans, Streptococcus sanguis, Streptococcus salivarius, Lactobacillus casei, Actinomyces viscosus were mixed or mixed together, resulting in these Cariogenic bacteria broth pH (except Streptococcus salivarius), the content of lactic acid in the broth greatly reduced, acetic acid, propionic acid content increased.
