The ability of oral lactobacilli to coaggregate with streptococci and actinomycetes was investigated. Of the 7 species of lactobacilli studied, only two were capable of coaggregation and the coaggregation was restricted to streptococci. Lactobacillus salivarius strains (2/4) coaggregated with Streptococcus salivarius, Streptococcus gordonii, Streptococcus crista and tufted Streptococcus sanguis II strains. Lactobacillus fermentum (2/3) coaggregated with S. gordonii and S. sanguis. The coaggregation between L. salivarius and S. salivarius, S. gordonii or tufted S. sanguis II strains was mediated by a protein on the surface of the lactobacilli and was not inhibited by lactose. The coaggregation between L. fermentum and the streptococci was mediated by protein on the surface of the streptococci and was inhibited by lactose.
研究了口腔乳酸杆菌与链球菌和放线菌的共聚能力。在所研究的7种乳酸杆菌中，只有两种能够共聚，且这种共聚仅限于链球菌。唾液乳杆菌菌株（2/4）与唾液链球菌、戈登链球菌、嵴链球菌和丛生血链球菌II菌株共聚。发酵乳杆菌（2/3）与戈登链球菌和血链球菌共聚。唾液乳杆菌与唾液链球菌、戈登链球菌或丛生血链球菌II菌株之间的共聚是由乳酸杆菌表面的一种蛋白质介导的，且不受乳糖抑制。发酵乳杆菌与链球菌之间的共聚是由链球菌表面的蛋白质介导的，并受乳糖抑制。
