Conoidasida es una clase de parásitos apicomplejos que causan graves enfermedades en los animales y seres humanos. [1] [2] Los organismos de este grupo, tienen en el extremo de su células un órgano complejo característico, formado por citoesqueleto y orgánulos, denominado complejo apical (api-complex en inglés).

Conoidasida is a class of parasitic alveolates in the phylum Apicomplexa. The class was defined in 1988 by Levine [1] and contains two subclasses – the coccidia and the gregarines. All members of this class have a complete, hollow, truncated conoid.

The class is divided into four orders, which are distinguished by the presence or absence of various asexual and sexual stages: 1. Order AgamococcidioridaLevine-1979 2. Order EucoccidioridaLéger & Duboscq-1910 3. Order IxorheoridaLevine-1984 4. Order ProtococcidioridaKheisin-1956 The order Eucoccidiorida is divided into two suborders. These two gro...
Transmission
Infected animals spread spores called oocystsin their stool. The oocysts mature, called sporulation. When another animal passes over the location where the feces were deposited, it may pick up the spores, which it then ingests when grooming itself. Mice may ingest the spores and become infected. When another animal eats the mouse, it becomes infected. Some species of coccidia are transmissible to humans, including toxoplasma and cryptosporidium.
Infection
Inside the host, the sporulated oocyst opens, and eight sporozoites are released. Each one finds a home in an intestinal cell and starts the process of reproduction. These offspring are called merozoites. When the cell is stuffed full of merozoites, it bursts open, and each merozoite finds its own intestinal cell to continue the cycle.
Symptoms of infection
As the infection continues, millions of intestinal cells may become infected. As they break open, they produce a bloody, watery diarrhea. This can cause dehydration, and can lead to death in young or small pets.Coccidian infections display symptoms mainly from the digestive tract including diarrhea, inflammation, intestinal pain or damage, vomiting, and irregular nutrition. These can lead to weight loss or reduced growth development, anemia, exhaustion, and even death in severe cases.

Los gametos maduros se desarrollan intracelularmente y el cigoto es generalmente inmóvil.
Conoidasida es una clase de parásitos del filo Apicomplexa. Los organismos de este grupo tienen un orgánulo característico terminado en punta en un extremo de su membrana externa. Este complejo apical incluye vesículas llamadas roptries y micronemas, que se abren en el anterior de la célula.
