Trichonymphidae. Genus: Trichonympha. Trichonympha is a genus of single-celled, anaerobic parabasalids of the order Hypermastigia that is found exclusively in the hindgut of lower termites and wood roaches. [1] Trichonympha ’s bell shape and thousands of flagella make it an easily recognizable cell. [2]

Aug 7, 2010 · Description and Significance. Parabasalids (phylum Parabasalia) are anaerobic flagellated protists which contain at least one parabasal apparatus consisting of a parabasal body (Golgi complex) and a parabasal filament. Parabasalids can be distinguished by the presence of the microtubular axostyle-pelta complex, composed of a sheet of cross ...
Dec 31, 2016 · General Characteristics. Parabasalia is a clade of anaerobic protists , almost all of which are flagellates. Parabasalians are characterized by the presence of a parabasal body (a densely packed Golgi complex that is associated with striated fibers connected to the basal bodies), hydrogenosomes (anaerobic derivatives of mitochondria), closed pleuromitosis with an extranuclear mitotic spindle ...
The metamonads are a large group of flagellate amitochondriate microscopic eukaryotes. Their composition is not entirely settled, but they include the retortamonads, diplomonads, and possibly the parabasalids and oxymonads as well. These four groups are all anaerobic (many being aerotolerant anaerobes), occurring mostly as symbiotes or ...
The parabasalids are a group of flagellated protists within the supergroup Excavata. Most of these eukaryotic organisms form a symbiotic relationship in animals. These include a variety of forms found in the intestines of termites and cockroaches, many of which have symbiotic bacteria that help them digest cellulose in woody plants. Other species within this supergroup are known parasites, and ...
Giardia intestinalis (synonyms: G. duodenalis, G. lamblia) is a parasite of the small intestine of humans and many animals, and several genetic lineages (assemblages) exist. Two of these lineages, assemblages A and B, are anthropozoonotic; humans may be infected from a wide variety of both domestic and wild animals.
