Figure 1: Negatively Stained Transmission Electron Micrograph of Salmonella typhimurium. S. typhimurium negatively stained with 1% uranyl acetate. This low magnification micrograph depicts a single bacterium possessing multiple flagella; the arrow indicates one of these flagella. Protein aggregates from the media are visible as light-colored circles. Bar = 1 µm.

Figure 3: Enlarged Views of Negatively Stained Salmonella typhimurium and Campylobacter jejuni Bacterial Flagella. (A) S. typhimurium flagellum, stained with 1% uranyl acetate, showing the helical nature of its flagella protein structure. (B) C. jejuni negatively stained with 1% uranyl formate, highlighting the parallel protein structure of its flagella. Bar = 50 nm.

Figure 5: Transmission Electron Micrograph of a Negatively Stained Fimbriae Radiating from Salmonella typhimurium. S. typhimurium enlarged from an area of Fig. 1 (indicated by highlighted boxed area in the inset). Fimbriae, indicated by arrows, are evident radiating from the outer membrane of the bacterium. Bar = 100 nm.
