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.
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...

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,...

I. INTRODUCTION Coccidiosis caused by unicellular protozoa from the genus Eimeria is one of the major veterinary challenges in the poultry industry, causing annual losses of more than $14 billion worldwide (Blake et al., 2020). Eimeria spp. need to invade intestinal epithelial cells to replicate. This leads to destruction of the intestinal epithelia, inflammation, reduced nutrient absorption and secondary infections such as nonspecific enteritis (also referred to as dysbacteriosis),...

A multi study analysis was performed to compare the efficacy of salinomycin with narasin. The analysis was performed using data of 18 different anticoccidial sensitivity tests (ASTs) conducted over a 7-year period (2013-2019). The Eimeria isolates were collected in commercial farms from 13 different countries all using different coccidiosis control programmes. Sensitivity of Eimeria parasites to anticoccidial products can be assessed by performing AST trials (Cervantes & McDougald,...

I. INTRODUCTION Rapid development of an appropriate microbiota within a chicken gut is critical for its ongoing gut health and immunity (Meijerink et al., 2020). In natural circumstances the hen would pass her microbiota onto the chick, but in commercial conditions where eggs are set and hatched in a sterile hatchery this transfer is not possible and microbiota development is often from sources such as the environment (Dame-Korevaar et al., 2020). Development of a microbiota...

I. INTRODUCTION Coccidiosis is one of the main disease challenges affecting broiler production worldwide. This disease has a significant economic impact on the poultry industry and the global cost of coccidiosis in chickens linked to prevention, treatment, and performance losses is estimated at US$13 billion or US$0.20 per bird (Blake et al., 2020). Coccidiosis is caused by protozoan parasites of the genus Eimeria. Seven different Eimeria species are known to affect chickens, each...

Introduction Between 15 and 20 weeks of age, layer pullets undergo rapid physiological changes, including reproductive tract maturation, ovarian follicles development, increased calcium intake for medullary bone formation, and metabolic and hormonal adjustments to support daily egg production (Xin et al., 2022; Bahry et al., 2023; Noetzold and Zuidhof, 2025). These developmental events impose higher nutritional and immunometabolic demands. Consequently, pullets entering lay are...

1. Introduction Coccidiosis is the first and most economically significant parasitic disease afflicting chicken welfare and, consequently, the world’s poultry industry [1]. E. tenella is the causal agent of cecal coccidiosis, and this species is regularly isolated from broiler farms worldwide [2]. Chemoprophylaxis and live wild-type/attenuated coccidia vaccines are currently used as preventative methods [3,4]. Protective immunity can be achieved by infecting chickens...

1. Introduction Over the last few hundred years, humans have influenced the evolution of multiple animal species and different ecosystems involved in animal production [1]. This approach has led to the genetic change of domestic animals and has undoubtedly been driven by agriculture. The most important genetic changes in poultry production have occurred in the previous 60 years. Modern broiler chickens are likely the clearest example of these genetic improvements. Newborn chicks grow...
