Review on epidemiology, pathogenesis, treatment, control and prevention of gastrointestinal parasite of poultry

Gastrointestinal tract is one of the organ systems which infected by different pathogenic organisms specifically predilection sites for parasites (helminthes and protozoa) absorb nutrient predispose to another infection. The aim this review was provide an overview published information regarding epidemiology diagnostic approaches chicken helminthes infection coccidiosis. disease main constraints poultry production in parts world gastrointestinal parasite most common infections poultries directly predisposes others internal parasitic occur include cestodes, nematodes coccidian that may cause considerable damage great economic loss industry due malnutrition, decreased feed conversion ratio, weight loss, lowered egg death young birds. Furthermore, can make flock less resistant diseases exacerbate existing conditions. Poultry coccidiosis generates losses mortality, reduced body plus expenses related preventive therapeutic control. More research investigation risk factors should apply increase production.
