E. coli infection mechanism. Immunofluorescence deconvolution micrograph of Escherichia coli bacteria (centre). Bacterial DNA (deoxyribonucleic acid) is blue. Actin protein filaments, which make up part of the cytoskeleton, are green. 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 pedestals cannot be formed without the presence of the host cell protein tyrosine kinase Abl2, which is red.
