(A) Tg(mpeg1:mCherry-F;mpx:GFP) larvae (5 dpf) were injected intravenously with n = 200 T. carassii/fish or with PVP as control and survival was monitored over a period of 15 days. (B) Tg(mpeg1:mCherry-F;mpx:GFP) zebrafish (5 dpf) were treated as in A and sampled at various time points. At each time point, three pools of 3–5 larvae were sampled for real-time quantitative PCR analysis. Relative fold change of the T. carassii-specific heat-shock protein-70 (hsp70) was normalised to the zebrafish-specific ef1α and expressed relative to the trypanosome-injected group at time point zero. Bars indicate average and standard deviation (SD) on n = 3 pools per time point. Letters indicate significant differences (p<0.05), as assessed using One-way ANOVA followed by Tukey’s multiple comparisons test.
