| Flagella·Fig. 1 A–H. Flagella and cilia under scanning electron (A, B), transmission electron (C–E) and light microscopy (F–H). A sp.; this ciliate is attached to the skin of a fish; note the bundles of cilia (CIB) (× 3.000). B sp., ventral view of this ciliate parasitic on fish, note the concentric rows of cilia (× 2.000). C ; section through the periphery of a young trophont, which has just entered the skin of the fish host (× 40.000). D, E ; note that the flagellum of trypanosomes contains a (PA) as well as the axoneme (AX) (× 35.000). F of do not show their short flagellum with light microscopy (× 2.200). G Trypanosoma cruzi; S-shaped trypomastigote form within mammalian blood (× 2.000). H ; nonfeeding mastigote stage from freshwater (× 2.100). AX, axoneme; B, basal body; CI, cilia; CIB, bundles of cilia; E, erythrocyte; EX, F, flagellum; IM, inner two membranes of M, membrane; MI, mitochondrion; N, nucleus; OM, outer membrane of pellicle; PA, |
