    Parabasalid

    Group of flagellated protists

    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 include human pathogens. Wikipedia

    Trichomonas vaginalis belongs to phylum Parabasalia, a grouping of microareophilic, single-cell flagellates that harbor H 2-producing organelles called hydrogenosomes [67].Over 400 parabasalid species have been described, and a recent analysis of morphological and phylogenetic data classified these into six phylogenetic groups: Trichomonadea, Tritrichomonadea, Hypotrichomonadea ...

    Parabasalia belongs to the supergroup Excavata, subgroup Metamonada , , , , , , and consists of single-celled flagellated eukaryotes that include parasites and commensals of vertebrate hosts, commensals and endosymbionts of invertebrates, and a few described free-living species. Among the parasitic parabasalids, several are important agents of ...

    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 ...

    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-linked microtubules that are the ...

    The phylum Parabasalia includes very diverse single-cell organisms that nevertheless share a distinctive set of morphological traits. Most are harmless or beneficial gut symbionts of animals, but some have turned into parasites in other body compartments, the most notorious example being Trichomonas vaginalis in humans. Parabasalians have garnered attention for their nutritional symbioses with ...

    Parabasalids (Parabasala or Parabasalia) are a diverse assemblage, containing hundreds of described species, almost all of which are parasites, commensals, or beneficial symbionts of animals. There are two basic morphological types of parabasalids. Parabasalids of the first type have a single nucleus associated with a single cluster of a few ...
