Adhesion to and invasion of human colon carcinoma Caco-2 cells by Aeromonas strains.

The enteropathogenicity of Aeromonas strains that showed mannose-resistant adhesion to INT407 cells was evaluated by infecting Caco-2 cells and observing them by light and electronmicroscopy. Five of six strains adhered in large numbers to Caco-2 cells in the presence of mannose and caused cytopathic effects. Two strains of Aeromonas spp.
