Coccidiosis in poultry
Coccidiosis is a protozoal disease causing diarrhea, ,weight loss and decreased production in poultry. It can be fatal. Prevention is key and is achieved with use of anticoccidials or vaccination. Diagnosis is by fecal flotation to detect oocysts, often in combination with characteristic necropsy findings. Coccidiosis is caused by protozoa of the phylum Apicomplexa, family Eimeriidae. Most species affecting poultry belong to the genus Eimeria and infect various intestinal sites. The disease course is rapid (4–7 days) and is characterized by parasite replication in host cells with extensive damage to intestinal mucosa. Coccidia in poultry are generally host-specific, and the different species infect specific portions of the intestine. However, in game birds, including quail, the coccidia may infect the entire intestinal tract. In poultry, game birds reared in captivity, and wild birds, coccidiosis occurs worldwide.
Each year, U.S. poultry producers raise about 7 billion broilers. They use a combination of antibiotics and vaccines to protect these birds from infectious diseases. Antibiotics are critical to ongoing efforts to fight off diseases and infections; they have been able to kill or stop growth of many different kinds of protozoa and parasites as well as bacteria.
One major disease of chickens -- coccidiosis -- is named after intestinal parasites collectively referred to as coccidia, which are...
