Foaina (foe-een-a) is one of the trichomonad flagellates - mostly endobiotic with four flagella arising from a point near the front of the cell. Three flagella project to the side or forwards, and one is directed to the rear. Usually with several cytoskeletal structures, an axial axostyle made of microtubules which encloses the nucleus anteriorly, as well as a costa which often lies under one of the flagella. The axostyle projects from the posterior end of the cell. From Cryptotermes. Phase contrast.

Calonympha are multinucleate polymastigotes parabasalid flagellates of about 70-80 µm long. The anterior part is occupied by several crown of akaryomastigonts and karyomastigonts each of which composed of four anteriorly directed flagella, a posterior axostyle and a nucleus in karyomastigonts. The posterior part contains an axostylar trunk a bundle composed of the axostyles of the karyomastigonts and wood particles. This species, Calonympha grassii, is from Neotermes jouteli. The anterior part is occupied by karyomastigonts bearing flagella and at the posterior end the protruding axostyle is typical (phase contrast).

Foaina (foe-een-a) is one of the trichomonad flagellates - mostly endobiotic with four flagella arising from a point near the front of the cell. Three flagella project to the side or forwards - sometimes sticking together, and one is directed to the rear. Usually with several cytoskeletal structures, an axial axostyle made of microtubules which encloses the nucleus anteriorly, as well as a costa which often lies under one of the flagella. The axostyle projects from the posterior end of the cell and is adapted to form a holdfast which attaches the cell to a piece of debris. From the termite Cryptotermes. Phase contrast.

Foaina (foe-een-a) is one of the trichomonad flagellates - mostly endobiotic with four flagella arising from a point near the front of the cell. Three anterior free flagella and one recurrent one adhering to the cell body only on its proximal part. Usually with several cytoskeletal structures, an axial axostyle made of microtubules which encloses the nucleus anteriorly, as well as a costa which often lies under one of the flagella. The axostyle projects from the posterior end of the cell and may be adapted to form a holdfast which attaches the cell to a piece of debris. Parabasal body (dictyosomes) rod-, disc- or V-shaped. Consumes particles of wood. his image shows the three anterior flagella clearly. From the termite Cryptotermes. Phase contrast.

Large hypermastigid (450-500 µm) symbiont in Mastotermes darwiniensis. Body broadly triangular in shape with an anterior dome-shaped rostrum completely flagellated. Cell body covered with longitudinal rows of flagella except the amoeboid posterior part which is separated by a girdle and used for wood ingestion. The nucleus is situated in the anterior region; the axostylar fibres surround the nucleus and some group backwards to form an axial axostylar trunk.

Foaina (foe-een-a) is one of the trichomonad flagellates - mostly endobiotic with four flagella arising from a point near the front of the cell. Three anterior free flagella and a recurrent one adhering to the cell body only on its proximal part. Three flagella are tightly grouped together, separating only at their distal ends. Usually with several cytoskeletal structures, an axial axostyle made of microtubules which encloses the nucleus anteriorly, as well as a costa which often lies under one of the flagella. The axostyle projects from the posterior end of the cell and may be adapted to form a holdfast which attaches the cell to a piece of debris. Parabasal body (dictyosomes) rod-, disc- or V-shaped. Electron microscopy has shown the trichomonad characters and particularly the presence of an infrakinetosomal body similar to that of Tritrichomonas. About 20 species living in the intestinal tract of vertebrates. other species live in the gut of invertebrates, especially arthropods such as termites and roaches, coleoptera, tipulid larvae and myriapods. Nucleus evident near front of cell, axostyle extending along the axis of the cell and out of the posterior end. From the termite Cryptotermes. Differential interference contrast.

Caduceia (cad-you-see-a) a devescovinid flagellate from the termite Cryptotermes. There is a microtubular axostyle extending the length of the body, but anteriorly it wraps around the nucleus. The globules around the nucleus are elements of the Golgi apparatus (dictyosomes). Finely granular region around the axostyle just posterior to the nucleus is the bacterial cup with large numbers of endosymbiotic bacteria. There is a small indentation just below the apex and to the upper left. This is the point of insertion of the flagella. Food vacuoles contain bacteria or small pieces of wood. Differential interference contrast.
