The environment in the human intestine is low in oxygen. This affects virulence gene expression of enteropathogens including Shiga toxin-producing E. coli (STEC) and enables mucosal colonization by oxygen-sensitive commensal bacteria. To simulate the oxygen-restricted milieu at the intestinal epithelium, we have developed a vertical diffusion chamber model (VDC) which allows infection of polarized human intestinal epithelia under microaerobic conditions. In this chapter, we present a detailed protocol for performing STEC infections in the VDC system and subsequent analysis of STEC pathogenesis.
