[Abstract]  Biofilms are sessile communities of microbial cells embedded in a self-produced or host-derived exopolymeric matrix. Biofilms can both be beneficial or detrimental depending on the surface. Compared to their planktonic counterparts, biofilm cells display enhanced resistance to killing by environmental threats, chemicals, antimicrobials and host immune defenses. When in biofilms, the microbial cells interact with each other and with the surface to develop architecturally complex multi-dimensional structures. Numerous imaging techniques and tools are currently available for architectural analyses of biofilm communities. This allows examination of biofilm development through acquisition of three-dimensional images that can render structural features of the sessile community. A frequently ... [摘要]  生物膜是嵌入自生或宿主衍生的外聚合物基质中的微生物细胞的固着群落。根据表面,生物膜可以是有益的或有害的。与浮游生物相比,生物膜细胞表现出更强的抗环境威胁,化学物质,抗菌药物和宿主免疫防御能力。当处于生物膜中时,微生物细胞彼此相互作用并与表面相互作用以形成结构复杂的多维结构。目前,许多成像技术和工具可用于生物膜群落的建筑分析。这允许通过获取可以呈现无柄群落的结构特征的三维图像来检查生物膜的发展。经常使用的工具是共聚焦激光扫描显微镜。我们提出了一个详细的协议,以生长,观察和分析呼吸道人类病原体,百日咳博德特氏菌的生物膜在空间和时间。

【背景】百日咳博德特氏菌(Bordetella pertussis)是上呼吸道的专性人类病原体,引起百日咳或百日咳(Mooi,2010; Dorji et al。,2018)。 B的生物膜。百日咳在各种人造表面上以及静态,摇动和流体流动条件下形成(Mishra et al。,2005; Sloan et al。,2007 ; Serra et al。,2011)。对这些生物膜的显微评估表明,这种细菌产生不规则形状的微集落,由流体通道分隔,嵌入由细胞外DNA(eDNA),蛋白质和多糖组成的外聚合物基质中(Parise et al。,2007; Sloan et al。,2007; Serra et al。,2008; ...
