Figure 1

Adhesion to HeLa cells and ultrastructural analyses of aggregative C. freundii. Micrographs A and B show the adherence pattern displayed by aggregative C. freundii 205 (EACF 205) and diffusely adherent C. freundii 047, respectively. For comparison, AA pattern displayed by prototype EAEC strain 042 is shown in the micrograph C. Electronic micrographs of EACF 205 are shown in the frames D and E. Both planktonic and surface-associated EACF cells did not displayed fimbrial structures; however, an extracellular matrix was detected surrounding the bacterial cells (arrows in frames D and E).
