Bacterialdensity, surface contact and physiological signals are stimulating factors of swarming motility.
菌细胞密度、表面接触和生理学信号均可成为群集运动的刺激因素。

RESULTS:The biofilm thickness and bacterialdensity in caries-active group were significantly higher than that in caries-free group (P<0.05);
结果:高龋组变形链球菌临床分离株的生物膜厚度和细菌分布密度显著高于无龋组(P<0.05);

The topography of bac observed by SEM showed that bacterialdensity on the GAC was reduced along water flow direction and coccus and bacilli were the main bacteria.
