E. coli infection mechanism. Immunofluorescence deconvolution micrograph of Escherichia coli bacteria (rods) infecting an intestinal cell. The intestinal cell's nucleus is the large blue object. Bacterial DNA (deoxyribonucleic acid) is also blue. Actin protein filaments, which make up part of the cytoskeleton, are red. Here the actin filaments are causing protrusions on the cells' membranes known as pedestals, which help this pathogenic bacteria to attach to intestinal cells. The formation of these pedestals is catalysed by the bacterial outer membrane protein intimin, which is yellow.
