Mastigina
From the collection
Drawings by Guy Brugerolle
| Description of Mastigina: Amoeboid monopodial cells with one flagellum, long or short, active or inactive, and always attached to an anterior nucleus. There is no posterior uroid, and there are several nuclei in one species. The nucleus has a large, central endosome, and mitosis includes division of the endosome. Mastigina hylae, which is endocommensal in intestine of toads, has solitary basal bodies connected to the nucleus by a cape or cone of microtubules. The single flagellum may not have the usual 9+2 arrangement of microtubules in the axoneme. A lateral ribbon of microtubules extends from the basal body to the cell surface. Secondary nuclei, which occur in large cells, bear one basal body without a flagellum and have a few associated microtubules. Some species may have a polymorphic life cycle (Goldschmidt, 1907). Type species: Mastigina chlamys Frenzel, 1897. |
