Extended Data Fig. 7: A selection of TEM micrographs taken from the hindgut of a fly at 11 dpi.
From: Trypanosoma brucei colonizes the tsetse gut via an immature peritrophic matrix in the proventriculus
a, An overview of the hindgut of an infected fly. The epithelial cells of the hindgut are distinctive (HGE) and the PM can be seen. In this region, material presumably from degraded and discarded PM can be seen (*). Scale bar 20 µm. b–d, Empty cyst-like body with no visible parasites (*). Scale bars 10 µm, 10 µm and 5 µm, respectively. e, f, Trypanosomes with abnormal morphology in the ectoperitrophic space of the hindgut. Arrowheads indicate the presence of parasites with multiple flagella. Scale bars 5 µm and 10 µm, respectively. For TEM analysis refer to Supplementary Fig. 4.
