Species diversity of coccidia of turkeys at the farms of the Leningrad region

Coccidiosis is a common disease, the causative agent of which are parasites from the genus Eimeria, the order Coccidia. Annually, this disease causes enormous economic damage to industrial poultry. The Indian-breeding industry is no exception. The most susceptible to the disease are young individuals at the age of about 6 weeks. Coccidia parasitize in the gastrointestinal tract of birds, disrupting the digestive process in various parts of the intestine, and even can cause death of birds. Effective methods of treatment of coccidiosis have not yet been developed, so the single way to stop it is -preventive measures, constant monitoring of circulating species of Eimeria on the territory of poultry farms, the use of drugs coccidiostatics- to prevent outbreaks of the disease and vaccination with attenuated live vaccines. Studies were carried out to determine the species composition of coccidia cultures from two farms of the Leningrad region. Studies were carried out from the biological material (droppings) of turkey. From the obtained material, a culture of coccidia was isolated according to generally accepted methods. The species belonging of the isolated Eimeria, their morphological and biometric properties were determined. Identification were based on the clinical, pathological, morphological and biometric characteristics. As a result of the assays, the species composition and territorial distnbution of turkey Eimeria in the Leningrad region were determined. Species have been identified: E. adenoeides, E. meleagrimitis. This is one of the most pathogenic species of coccidia, which are quite widespread in poultry farms around the world. It is necessary to monitor regularly the condition of these turkey farms for coccidiosis in order to plan its prevention as effectively as possible.
