As is clear from the above, chickens and turkeys differ in the types of E. parasites that parasitize, and the E. parasites have significant host specificity. The types of parasites in chickens are other birds and animals. It does not parasitize, but the basic life cycle is almost the same even if the types are different. In the case of chickens, chickens ingest mature oocysts from the outside together with food. Then, the oocyst wall is broken in the muscle and stomach, and 4 sporocysts are released from 1 oocyst,
The sporocysts are sent to the intestine, and two sporozoites are extruded from one sporocyst by the action of the enzyme (mainly trypsin). Sporozoites invade the intestinal mucosal cells and repeat division to become schizonts containing several to several hundred merozoites within 1-2 days. The merozoites inside the schizonts break through the schizont's cell membrane and spill out to the intestine. Invades the cells of the mucous membrane. In the cells of the intestinal mucosa, some of the merozoites repeat similar asexual reproduction, but most of them migrate to sexual reproduction (gametgonii) and become microgamate (male) and macrogamate (female), which are mated and fertilized. Then it becomes oocysts, which are shed from the intestinal mucosa and excreted in feces. When excreted out of the body, the oocysts are immature and not infectious, but become mature infectious oocysts within a few days, and the above-mentioned series of cycles are repeated thereafter.

Animals infected with coccidiosis-producing protozoa such as Eimeria protozoa exhibit symptoms such as diarrhea and bloody stools, and often die when treatment is delayed or when symptoms are severe, and do not result in death. Development is also hindered. For this reason, coccidiosis is one of the most serious animal diseases, and poses a serious problem especially for poultry breeders (poultry farmers) who handle a large number of poultry.

Conventionally, in the prevention and treatment of coccidiosis in animals, chemotherapeutic agents consisting of antibiotics (polyether antibiotics such as salinomycin) and synthetic antibacterial agents (sulfa drugs) and biological preparations such as vaccines. Has mainly been used. However, antibiotics and chemotherapeutic agents have problems such as occurrence of side effects and diminished effect due to acquisition of resistance to the drug. In the case of a vaccine, it was used only for prevention and could not be used for treatment. Moreover, when humans eat meat, eggs, etc. of animals to which these drugs have been administered, there is a problem of migration of the drugs remaining in the animal body to the human body, and there are severe restrictions on the amount used and the administration period.
