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.

1. Introduction Avian coccidiosis, caused by Eimeria spp., is one of the vulnerable enteric diseases and is endemic in vast areas of the tropical and subtropical regions [1]. It reduces growth performance affecting chicken meat production and accounts for about 30% of the total expenses on medications and other pharmacological products used to control poultry diseases [2]. Out of seven recognized species, E. acervulina, E. necatrix , and E. tenella cause...

1. Introduction Coccidiosis is a parasitic disease caused by an apicomplexan parasite of the genus Eimeria, which infects different parts of the intestinal tract depending on the species of Eimeria [1]. Eimeria spp. invade intestinal cells and cause physical damage to the intestinal epithelium, producing hemorrhagic diarrhea and disrupting the normal functioning of the intestinal tract [2]. This leads to impaired nutrient absorption and compromised gut health [3]. On the other hand,...

Introduction Coccidiosis is a parasitic infection caused by Eimeria spp and persistently affecting broiler chicken, causing high morbidity, impaired growth, and mortality [1]. Unlike many other protozoan parasites, Eimeria spp exclusively invades the intestinal epithelium showing high tissue specificity [2]. Eimeria (E.) maxima is characterized by producing the largest oocysts and male gamonts among the other species infecting chicken [3]. E. maxima particularly infects chickens at...
