Atypical EPEC (aEPEC) strains are part of group of pathogens capable of forming the Attaching and Effacing (A/E) lesion. This lesion is characterized by intimate adherence of bacteria to enterocytes, and microvilli destruction. The genes responsible to cause that lesion are located in a pathogenicit...
ORGANISM(S): Escherichia coli O55:H7 
Typical enteropathogenic Escherichia coli (EPEC) O55:H7 is regarded as the closest relative of enterohemorrhagic E. coli (EHEC) O157:H7. Both serotypes usually express the γ1 intimin subclass and trigger actin polymerazation by the Tir-TccP pathway. However, atypical O55:H7 strains capable of trigg...
ORGANISM(S): Escherichia coli 
EPEC wild type E2348/69 (strain O127:H6) bacteria were grown overnight (ON) in LB medium (Sigma-Aldrich) at 37°C without shaking, diluted 1:40 into DMEM-HEPES (Gibco, Israel) medium and incubated for 3h at 37°C without shaking to exponential phase (optical density (OD) ~ 0.6). Bacteria were plated o...

Atypical enteropathogenic E. coli virulence markers
Innate immune responses must be regulated in the intestine to prevent excessive inflammation. Here, using gene reporter mice, we show that a subset of mouse colonic macrophages constitutively produced the anti-inflammatory cytokine IL-10. In mice infected with Citrobacter rodentium, which is consid...
