| Popis: | The surface structures of the cells of Pasteurella pneumotropica from mice and Pasteurella multocida from rabbits were examined by transmission electron microscopy after ruthenium red staining and polycationic ferritin labelling. P. pneumotropica strains ATCC 35149 and K 79114 had slight extracellular fibrous materials associated with cell walls with ruthenium red staining. Ferritin labelling method revealed thick strands or sparsely ferritin-labelled materials on the cell surface of the strains. P. multocida strains Pm-78 and P-2440 had ferritin-labelled capsules surrounded with the cell wall. Strain Pm-78, which was serotyped as A:12, had a thick capsule, whereas serotype -:3 strain P-2440 had a thin and irregular capsule. |
