Retortamonas intestinalis is Protozoo flagellated pertaining to the order Retortamonadida that parasite digestive Tract of Human and others Primates
usually presents/displays a size inferior to 10 μm .
They lack certain Orgánulos as they are Mitocondrias and Apparatus of Golgi .
has Hospedador solely (monoxeno), is cosmopolitan and has two forms of life in its vital cycle:
Trofozoito : it presents/displays a size around 5-9 μm of length and one pear-shaped morphology. owns 2 Flagella one of them long one and associated to Citostoma, specialized zone through which obtains the food, and the other, in the previous zone, associated to a function of Motilidad . It has a unique nucleus that get ready in the previous zone, near the point of insertion of flagella. The trofozoito is the vegetative form that is fed and it reproduces.
Cyst : it presents/displays a size around 6 μm of length and one oval morphology. It does not present/display flagella nor citostoma, although they are possible to be gotten to appreciate rest of these structures, like axonemas intracytoplasmic. It has a unique nucleus that get ready more or less in the central zone. The cyst is the infecting vegetative form and of resistance.
Feeding by Phagocytosis, through citostoma, of particles of the digestive tract.
Reproduction by longitudinal binary division. They do not present/display sexual reproduction.
Vital cycle and infection
R. intestinalis as much lives like At the table in Internal thickness on the human being as on other primates. Since it presents/displays a unique hospedador, its vital cycle is direct and takes place through the cysts, that are eliminated by Lees and they already present/display infectious capacity. When these cysts are ingested by a new hospedador, the cysts arrive at the heavy intestine where they generate trofozoitos that are fed and reproduced, giving rise to new cysts and thus closing his vital cycle.
R. intestinalis is considered like a apatógeno parasite, since it does not cause any type of ailment, with the exception of certain Diarrheas due to the irritation of Mucous intestinal when they increase of considerable form the levels of parasitemia.
R. intestinalis is a little parasite of Prevalence and, although concrete data do not exist on the matter, it does not seem that a high number of infected individuals exists.
