EPEC 30-5-1(3) forms wild-type A/E lesions. (A and B) Immunofluorescence microscopy of HeLa cells infected with EPEC 30-5-1(3) or wild-type EPEC and fixed, permeabilized, and colabeled with anti-PY (FITC) and Texas red phalloidin after 2 (A) or 4 (B) h of infection. (C) HeLa cells infected with either EPEC 30-5-1(3) or wild-type EPEC for 4 h, and labeled with anti-PY (FITC) and anti-Tir (rhodamine).
