Low (a, c) and high (b, d) magnification micrographs of immunogold-labeled T. forsythensis cells after antigen retrieval by heating with the microwave oven. Microwaved at 100˚ C with 1% citraconic anhydride. Moderately decreased cytoplasm (a, c) compared to control cytoplasm (Fig. 1) without damage to the ultrastructural integrity of cytoplasmic membrane and outer membrane (b, d). Immunogold-particles in (b) and (d) showed greater reactivity than the control (Fig. 1). CM, cytoplasmic membrane; OM, outer membrane; S, S-layer.
