Figure 2. A. polyphaga trophozoites associated with C. jejuni.

The fraction of A. polyphaga trophozoites associated with C. jejuni are shown as % of all counted trophozoites at 1 h, 24 h, 48 h and 72 h after infection. The trophozoites registered at each time point fall into one of the following categories: Trophozoites associated with viable C. jejuni only (squares), associated with heat killed C. jejuni only (circles), associated with both viable and heat killed C. jejuni (triangles) or associated with no C. jejuni (diamonds). Among the trophozoites associated with both viable and heat killed C. jejuni, the amount of viable C. jejuni were dominating at all time points except at 96 h. Data are based on three to five independent experiments for samples taken at 1 h–72 h and on one experiment for 96 h. Mean±95 confidence interval.
