A cocci-filament association was discovered in bacterial cultural studies of a subgingival plaque sample. Components were isolated and identified as Veillonella parvula and Eubacterium saburreum. A E. saburreum cell-associated material consisting of approximately 25% glucose and 70% protein was found which may play a role in the adherence of V. parvula to this filament. Acid end product analysis via gas liquid chromatography showed an uptake of lactic and succinic acids by V. parvula resulting in increased levels of acetic, propionic and n-butyric acids in mixed culture of the E. saburreum and the V. parvula strains. The ability of E. saburreum to adhere to nichrome wire and to glass surfaces as well as the secondary plaque forming ability of V. parvula indicates that these organisms may play a role in the maturation of human dental plaque.
在一项龈下菌斑样本的细菌培养研究中发现了球菌-丝状菌联合体。分离出的成分被鉴定为小韦荣球菌和龋齿真杆菌。发现了一种与龋齿真杆菌细胞相关的物质，其由约25%的葡萄糖和70%的蛋白质组成，这可能在小韦荣球菌附着于该丝状菌的过程中发挥作用。通过气相色谱法进行的酸性终产物分析表明，小韦荣球菌摄取了乳酸和琥珀酸，导致在龋齿真杆菌和小韦荣球菌菌株的混合培养物中乙酸、丙酸和正丁酸水平升高。龋齿真杆菌附着于镍铬丝和玻璃表面的能力以及小韦荣球菌形成继发性菌斑的能力表明，这些微生物可能在人类牙菌斑成熟过程中发挥作用。
