Fine structure of Bodo curvifilus Griessmann (Kinetoplastida: Bodonidae).
Bodo curvifilus Griessmann conforms in its fine structure to the criteria proposed for the genus Bodo, including the presence of subpellicular microtubules, a single large kinetoplast-mitochondrion, emergence of the 2 heterodynamic flagella from a subapical flagellar pocket, and the presence of a paraxial rod associated with the axoneme of each flagellum.  B. curvifilus possesses cytoplasmic bodies which resemble endosymbiotic bacteria.  These are similar to those found in Bodo saltans.  Bodo curvifilus can be distinguished ultrastructurally from Bodo caudatus and B. saltans by the presence in B. curvifilus of a hitherto unreported structure, "the microtubular prism," consisting of a bundle of 19 microtubules.  In cross section, 15 of these microtubules form a cross-linked prismatic array.  This microtubular bundle originates near the flagellar pocket and extends for several micrometers into the body of the organism where it follows the periphery of the cell and the long finger-like projections of the kinetoplast-mitochondrion.
