Podophrya

Podophrya Ehrenberg, 1838 (ref. ID; 2013)

From Dr. kuniyasu

Class Kinetofragminophora: Subclass Suctoria: Order Suctorida: Suborder Exogenina (ref. ID; 2013)

[ref. ID; 2013]
Body spherical to ovoid borne on hollow rigid stalk. There is no lorica. There are many capitate tentacles which are distributed over the entire body surface. Encystment is common. The macronucleus is rounded and reproduction is by exogenous budding. This is a common genus that may be easily confused with Prodiscophrya from which it may be distinguished by the method of budding only.

Podophrya grelli Dieckmann, 1985 (ref. ID; 4690 original paper) reported author and year? (ref. ID; 191)

Descriptions

Podophrya grelli n. sp., a host-specific ectoparasite of Stylonychia lemnae Ammermann and Schlegel, 1983, is described. Podophrya grelli has a life cycle with an alternation of generations. The infection is performed by an oval, ciliated swarmer (15-20 um), which attaches with some tentacles at the host cell. The swarmer delicates and induces the host cell to from a pellicular invagination accommodating the suctor. The invagination remains open to the culture medium. The swarmer rounds up, ingests the host cytoplasm by means of its tentacles and grows to the adult parasite (30-50 um). By inequal, in rare cases equal divisions new swarmer are formed. These leave the invagination and can infect new host cells. After a host cell degenerated due to the continuous loss of cytoplasm some parasites conjugate. One to 3, maximally 5 conjugating pairs per cell are formed. Increasing the food uptake the conjugants store granular material and grow considerably. The conjugants then get into the culture medium, remaining connected for some time at the bottom of the culture vessel before they separate. Exconjugants form a stalked cyst. By successive multiple fissions within the cyst up to 16 infectious swarmers are formed, which cannot be distinguished with the light microscope from the swarmer of the asexal generation. (ref.
