Escherichia coli O15:H7 adheres to and enters the PBRE cells. E. coli O15:H7 43894 or 43895 were incubated with the monolayer of PBRE cells at 100 MOI for 4 h. More 43895 bacteria adhered to and were internalized by the PBRE cells compared to 43894. (A) Giemsa staining showing 43895 aggregative adherence pattern (inverted microscope, original magnification, ×1000). (B,C) Transmission electronic microscope showing extracellular and intracellular bacteria. (D) 43895 appeared to divide within the vacuoles of the PBRE cells (Original magnification, ×10000).
