Ultrastructural features of T. kaiowa n. sp. revealed by TEM microscopy. a Flagellate invading Hi-5 cells via flagellum, and many transverse sections of the flagellum inside cell cytoplasm. b Small flagellates within tight vacuoles (indicated by black arrows) in the cytoplasm. c Transverse section of the flagellar pocket showing the typical structure of flagella, the absence of paraflagellar structure inside the flagellar pocket, prominent paraflagellar structure in free flagellum, and a small portion of the cytostome. d Longitudinal section of flagellate showing a deeply invaginated cytostome, compacted kinetoplast, and a multivesicular body probably containing viral particles. e Many acidocalcisomes in the cytoplasm. f Longitudinal sections of a dividing flagellate showing two nuclei. g Transverse section of flagella showing noticeable paraflagellar structure and lamella (black arrow). h Multiple glycosomes near the nucleus. i Network of tubules forming the spongiome adjacent to the flagellar pocket containing many vesicles. Abbreviations: N, nucleus; K, kinetoplast; Fp, flagellar pocket; F, flagellum; Cy, Cytostome; Pr, paraflagellar structure; Ac, acidocalcisomes; Spm, subpellicular microtubules; Mvb, multivesicular bodies; M, mitochondria; Sp, spongiome; v, vacuoles.
