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.

This scanning electron micrograph (SEM) of an untreated water specimen extracted from a wild stream mainly used to control flooding during inclement weather, revealed the presence of unidentified organisms, which included bacteria, protozoa, and algae. In this particular image, unidentified sheets of algae were wrapped in a mass of what appeared to be a mucoid amorphous biofilm. See PHIL 11713 for a colorized version of this image.Created: 2009

The genus Trichomonas includes polymorphic parabasalid flagellates (5-30 µm) with four free anteriorly directed flagella and a short recurrent flagellum associated with an undulating membrane shorter than the body; no free posterior recurrent flagellum. Costa relatively slender, axostylar trunk protruding posteriorly; parabasal body V-shaped with one or two long parabasal filaments. Amoeboid and polymastigotes forms present in natural or culture conditions. Several species living in the genitor-urinary tract of humans such as T. vaginalis, the mouth such as T. tenax or in the instestine of birds such as T. gallinae. This is Trichomonas vaginalis with four anterior flagella, undulating membrane, posterior axostyle, nucleus (Giemsa staining).

This scanning electron micrograph (SEM) of an untreated water specimen extracted from a wild stream mainly used to control flooding during inclement weather, revealed the presence of unidentified organisms, which included bacteria, protozoa, and algae. In this particular image, a number of unidentified oblong elliptical-shaped diatoms were featured, along side amorphically-shaped masses of organically-composed biofilm.Created: 2009
