FIG. 4.
Immunogold labelling of intimin γ The antiserum labelled all strains expressing intimin γ, and most strains including EHEC 85-170 (O157:H7) (a) displayed a uniform distribution of surface intimin, although strains ICC39 (O55:H−) and ICC57 (O55:H7) (b) showed a filamentous pattern of intimin staining. Intimin γ from strain ICC57 cloned into CVD206 [strain CVD206(pICC57)] displayed a uniform surface intimin distribution (c). Magnification, ×30,000.
