Examples of yellow fluorescent trypanosomes from proboscides of flies infected with mixtures of different TCS strains. Flies were dissected 23–39 days post-infection. A, B Gam2 RFP × 1/148 GFP; C, D 1/148 RFP × WG81 GFP; E, F Gam2 RFP × WG81 GFP; G intraclonal cross 1/148 RFP × 1/148 GFP. From left to right: phase contrast, green fluorescence, red fluorescence, merge of red and green fluorescence. Scale bar = 10 µm
