Trichonympha Leidy

Trichonympha (trick-owe-nymph-a) is one of the hypermastigid flagellates - flagellates with large numbers of flagella. They and the trichomonads made up the group called the parabasalids - almost all of which are endobiotic or parasitic. There is an anterior symmetrical rostrum, and the numerous flagella arise from this region and from the region of the body immediately behind. There are also spirochaetes attached to the back of the body. The nucleus is a large structure lying some distance behind this. Cytoskeletal fibres with associated dictyosomes form bands running from the points of flagellar insertion through the anterior part of the body. Food vacuoles with particles of wood are found in the posterior part of the body. From the termite Reticulotermes. Differential interference contrast.

They and the trichomonads made up the group called the parabasalids - almost all of which are endobiotic or parasitic. There is an anterior symmetrical mobile rostrum, and the numerous flagella arise from this region and from the region of the body immediately behind. This is an optical section through the rostrum.
