Ultrastructure of the strain CP021. a General view of the anterior part of the cell. b Flagellar tip. c Longitudinal section through flagellar pocket. d Transverse section through a flagellar pocket with two flagella. e Four kinetosomes (indicated by numbers). f, g longitudinal and transverse sections of the kinetoplast. h Dividing kinetoplast. i Golgi apparatus. j Interphase nucleus of irregular shape. Black arrowhead shows vesicles detaching from the flagellar membrane, white arrowheads—oblique fibrils between the axoneme and plasmalemma, white arrows—kinetoplast appendage containing kDNA fibrils, asterisk—microtubules supporting the flagellar pocket wall. Abbreviations: ac, acidocalcisomes; af, apex of the flagellar tip; ag, Golgi apparatus; ax, axoneme; fl, flagella; fp, flagellar pocket; gl, glycosomes; kp, kinetoplast; ks, kinetosomes; nu, nucleus; pr, paraxial rod. Scale bars: a 2 μm, b 0.25 μm, c, e 1 μm, d, fj 0.5 μm
