Objective To establish Enterohemorrhagic Escherichia coli (EHEC) O157∶H7 attached HeLa cell model for further study on its pathogenic mechanism. Methods HeLa cells and Escherichia coli O157∶H7 were incubated together in different condition (amount of bacteria
incubation time). In regard to the amount of bacteria attached
we decided the best condition for O157∶H7 to infect HeLa cells and identified the characterized A/E (attaching and effacing) lesion by FAS (fluorescence actin staining). Results The best condition is that 1×10
5
CFU O157∶H7 and HeLa cells were incubated together for 4 h
under which the specific A/E lesion can be observed. Conclusion EHEC O157∶H7 attached HeLa cell model has been successfully established.
