Cristamonadida

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.

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.

Group of cells 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 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.

Caduceia (cad-you-see-a) a devescovinid flagellate from the termite Cryptotermes with three free anterior flagella and a thick cord-like or ribbon-like recurrent flagellum. Three of the flagella can be seen extending to the right, and one lies adjacent to the left side of the body. Phase contrast.

Caduceia (cad-you-see-a) a devescovinid flagellate from the termite Cryptotermes. The anterior regions of two cells show the axostyles, the nucleus, bacterial cups - the finely granular regions posterior to the nucleus. The irregular region around the left hand nucleus is formed by the dictyosomes. Differential interference contrast.

Caduceia (cad-you-see-a) a devescovinid flagellate from the termite Cryptotermes. With three free anterior flagella and a thick cord-like or ribbon-like recurrent flagellum (not visible here). The recurrent flagellum adheres to the cell body along a variable length which is underlain by a cresta. There is no real undulating membrane. The body may be covered with short spirochaetes and short rod-like bacteria adhering in some areas. Axostyle fine, extending through body to project from the back of the cell. There is a microtubular axostyle extending the length of the body, but anteriorly it wraps around the nucleus. The front end of the cell can move freely, and for this reason Tamm called these organisms Rubberneckia, a term which has since become a verb to refer to motorway-accident-voyeurism. There is some sign of the dictyosomes around the nucleus, although are better illustrated in other micrographs. Phase contrast.

Caduceia (cad-you-see-a) a devescovinid flagellate from the termite Cryptotermes with three free anterior flagella and a thick cord-like or ribbon-like recurrent flagellum. This is the nucleus, flagellum, dictyosome and axostyle complex, sometimes called the karyomastigont, which has been extracted from cells. Phase contrast.

Coronympha (corr-o-nymph-a), a calonymphid flagellate which is a multinucleated trichomonad flagellate. All members of this group have multiple nuclei each with its own set of flagella. This genus has 8 or 16 karyomastigonts arranged in a single anterior circle. Each karyomastigont comprises three anterior flagella, a thick recurrent flagellum with an adherent proximal portion underlain by a cresta, an axostyle-pelta complex, and a drop-shaped parabasal close to the nucleus. The axostylar trunks are independent and only meet posteriorly, sometimes forming a caudal projection (see thumbnail). Phase contrast.
