Groups of red, green and yellow fluorescent trypanosomes. Trypanosomes from proboscides of tsetse infected with the TCS cross Gam2 RFP and 1/148 GFP (dissected 28 days post-infection). In A one red and one green fluorescent trypanosome are adjacent and appear to be attached together at their anterior ends by debris. In B one yellow fluorescent trypanosome (arrowed) appears joined to two red ones at the anterior. From left to right: phase contrast, Hoechst 33342 merge, green fluorescence, red fluorescence, merge of red and green fluorescence, merge with phase contrast image. Scale bar = 10 µm
