Abstract
Adherence to epithelial cells is a prerequisite for intestinal colonization by the bacterial pathogen, enterohemorrhagic Escherichia coli (EHEC). The deletion of minD, a cell division gene, in EHEC caused reduced adherence to human epithelioid cervical carcinoma (HeLa) and human colonic adenocarcinoma (Caco-2) cells as compared to wild-type. The minD mutant formed minicells and filaments owing to aberrant cytokinesis. Moreover, its ability to form microcolonies as typically seen in the co-cultures of wild-type with Caco-2 cells, was abolished. In conclusion, the present study highlights the importance of minD in regards to EHEC adherence to human epithelial cells.
