[Comparative study of Campylobacter pyloridis and Campylobacter jejuni under electron microscope].
Specimens were made by preparing the ultrathin sections after negative staining and ruthenium red staining. The specimens were observed under electron microscope. Results revealed that the shapes of Campylobacter pyloridis (Cp) and C. jejuni (Cj) were similar, but distinctive differences in their structures were observed. Cp had one to five sheathed flagella at one end with bulbous tips. Cj had only one unsheathed flagellum on each end without a bulbous tip. The cell body of Cp was longer than that of Cj. A layer of thick and dense delicate filament-like substance was attached to the surface of the cell body of Cp in the ultrathin sections with ruthenium red staining, in the case of Cj only a little of such a substance could be noted.
