Pseudotrichomympha are hypermastigids of large size (300-500 µm) with a rostrum bearing long flagella separated from the post-rostral part which is covered with flagella arranged in longitudinal or oblique rows. Axostylar filament in the anterior half of the body, central nucleus. At the time of writing, with about 20 species occurring in several termites such as Coptotermes, Heterotermes. Pseudotrichonympha hertwigi from Coptotermes acinaciformis (protargol).

Using a trichrome stain, this photomicrograph revealed the morphologic characteristics of a blue-stained Giardia intestinalis protozoa cyst (center). The Giardia parasite lives in the intestine of infected humans or animals. Millions of cystic protozoa can be released in a bowel movement from an infected human or animal. Giardia is found in soil, food, water, or surfaces that have been contaminated with the feces from infected humans or animals. You can become infected after accidentally swallowing the parasite; you cannot become infected through contact with blood.Created:

Pseudotrypanosoma is a trichomonad flagellate with four anterior flagella and a recurrent flagellum associated with a conspicuous undulating membrane, but no free terminal portion. Undulating membrane reaching the posterior end sustained by a thick and contractile costa. Axostyle of moderate diameter and with a terminal bulbous expansion. Parabsal body very long and branched. The most known species is P. giganteum occurring in Porotermes adamsoni. Pseudotrypanosoma giganteum from Porotermes adamsoni long cell (phase contrast)

Barbulanympha (barb-you-lah-nymph-a) is one of the trichonymphid hypermastigid flagellates found, in this vase, in the guts of the wood-eating cockroach, Cryptocercus. the flagella arise from the anterior portion of the cell, the most anterior region is a small rostrum. Strands, the parabasal apparatus, extend from the flagella down over the cell to the region of the single large nucleus lying about a quarter of the way down the cell. The parabasal apparatus is comprised of cytoskeletal fibres and associated dictyosomes. Phase 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 species of diatoms are seen to be caught up in an amorphous gelatinous biofilm, which had entrapped stream particulates as well.Created: 2009

Pyrsonympha are oxymonad flagellates with a spirally twisted and contractile pyriform cell body of 20-150 µm according to species. Four to eight flagella wrapped around the cell body with a posterior trailing portion. Nucleus anterior or median; contractile axostyle arising at the anterior end and traversing the body to protrude posteriorly with a sheath. Anterior finger-like holdfast to attach to the cuticle of the termite gut. Phagocytoses wood particles. Several species such as P. vertens and P. flagellata from Reticulitermes and Hodotermopsis. Pyrsonympha vertens from Reticulitermes lucifugus grassei showing the anterior holdfast, the nucleus and adherent flagella along the cell body (phase contrast).
