High resolution scanning electron micrographs of Trypanosoma copemani G2 trypomastigotes after incubation with Vero cells for 24 (a-c) and 48 h (d-g). a Parasite attached to cell that is blebbing around the cell attachment site and an arrow showing higher magnification of the same site. b Attachment of multiple parasites to a cell that appears to be blebbing. c Attachment of multiple parasites to a cell that appears to be blebbing. d Parasites embedded in the cell membrane. Arrow points to a visible flagellum, e Parasites embedded in the cell surface and some retain long flagella that extend out of the cell (arrow). f Parasite that appears to be degrading with a flagellum on the surface of a cell g Multiple parasites attached to the cell surface that appear to be degrading. Scale-bars: a, 2 μm and 1 μm; b-f, 2 μm; g 10 μm
