[Abstract] Patients with Crohn’s disease are abnormally colonized by adherent-invasive Escherichia coli (AIEC) bacteria (Chassaing and Darfeuille-Michaud, 2011). These bacteria are able to adhere to and invade intestinal epithelial cells (IEC), to replicate within macrophages, and were recently described to be able to form biofilms (Martinez-Medina et al., 2009; Chassaing and Darfeuille-Michaud, 2013). The reference strain of adherent-invasive E. coli is the strain LF82, associated with ileal Crohn’s disease (Darfeuille-Michaud et al., 1998).
This protocol described basic steps of a biofilm formation assay on I) non-cell-treated polystyrene microtiter plates and on II) paraformaldehyde-fixed I-407 IEC monolayers.
[摘要] 克罗恩病患者被粘附侵入性大肠杆菌（AIEC）细菌异常定植（Chassaing和Darfeuille-Michaud，2011）。 这些细菌能够粘附和侵入肠上皮细胞（IEC），在巨噬细胞内复制，并且最近被描述为能够形成生物膜（Martinez-Medina等人，2009; Chassaing和 Darfeuille-Michaud，2013）。 粘附侵入性E的参考应变。 大肠杆菌是与回肠克罗恩病相关的菌株LF82（Darfeuille-Michaud等人，1998）。
该方案描述了生物膜形成测定的基本步骤：I） 非细胞处理的聚苯乙烯微量滴定板和II）多聚甲醛固定的I-407 IEC单层。
