Biofilm migration videos

Video 1: Active detachment of bacterial cells from the frontline of interstitial biofilms and free movement of planktonic cells or small bacterial clusters were noticed after 24 h of biofilm culture in a humid chamber. Video 2: The dispersed cells seeded a nearby area and re-established a standalone “daughter” biofilm. The “daughter” biofilms expanded to merge with the primary biofilm and lead to migration of the interstitial biofilm.

视频1：在加湿培养箱中开展生物被膜培养24小时后，可观察到间隙生物膜前沿的细菌细胞发生主动脱离，同时浮游细菌细胞或小型细菌簇可自由移动。
视频2：脱离的分散细菌会在邻近区域定植，并重新形成独立的“子代”生物被膜。子代生物被膜会逐渐扩张并与原代生物被膜融合，最终引发间隙生物膜的迁移。
