Birds and mammals in the animal protozoal parasite disease that are characterized diarrhea and enteritis, bloody stool caused by parasites .
1. Agent
Eimeria protozoa is a pathogen belonging to Cryptosporidium and a kind of parasite disease. 9 is known as Cryptosporidium species, and current has a high specificity for the host. Coccidia is the most advanced protozoa and the life cycle has a asexual and sexual period then the almost pathogenicity appeared in the asexual period. When immunized with one type only because it does not form antibodies are protective for other types of coccidiosis. Oocystic resistance is resistance to alien environments in large and strong chemicals and can usually hold 1-2 years in the infectious nature.
2. Epidemiology
It occurs worldwide and competitive results in loss to the poultry industry. Transition to the current breeding population and density are causing an explosion occurs in the infected, the propagation path is as follows.
① infection by ingesting the excreted oocyst through the feces of the infected host system.
② oocyst is contaminated with dust come to move to the next cage by the wind.
③ propagated by the manager of boots or organizations, and other wildlife.
3. Clinical Signs
Due to a parasitic protozoa of epithelial cells in intestines, catarrhal or hemorrhagic enteritis then show bloody diarrhea. In laying hens, mortality is almost no and egg laying is reduced and the skin tends to fade. Coccidiosis in broiler is stunted and generally occurs most often between 35-40 days of age the chicks. Mortality is very high between 30 to 40 days of age, depending on the type of parasite.
4. Prevention and Treatment
1) Prevention
① it should conduct regular disinfection with disinfectants that effect.
② Oocyst has strong resistance against physical and chemical stimuli but the weak with respect to direct sunlight (ultraviolet rays), extremely dry and are killed by high temperatures. Therefore it recommended that the combination of hot water or flame sterilize and dry.
