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 In poultry, the gastrointestinal tract accounts for twenty percent of the energy expenditure of the whole body (Choct, 2009). This energy requirement is variable and dependent on numerous factors influencing the highly dynamic nature of the intestinal environment. The intestinal environment including the mucosal structure and function is influenced by many factors including environmental management, embryonic incubation, dietary ingredients, protein level,...

THE IMPORTANCE OF COCCIDIOSIS Coccidiosis is a parasitic disease of the intestinal tract of farm animals (poultry, swine, rabbits, many species of ruminants) that leads to considerable economical losses . It is caused by protozoa of the genuses Eimeria and Isospora, among others. The disease spreads from one...

INTRODUCTION Coccidiosis presently proves to be a major and pressing protozoan disease in the poultry industry worldwide (Dalloul and Lillehoj, 2006). Coccidiosis is caused by a protozoan parasite from the genus Eimeria. The life cycle of coccidial parasites includes asexual and sexual replication stages and begins when a bird ingests sporulated oocysts from the environment, as described by Conway and McKenzie (2007). After ingestion, four sporocysts contained in a...

Background Control and eradication of intestinal infections caused by protozoa are important biotechnological and medical challenges worldwide. The coccidial parasites Eimeria, Toxoplasma, Neospora and Cryptosporidium are the cause of serious diseases in humans and animals. Many of these intracellular protozoa affect the small intestine and produce devastating effects on immune compromised subjects [1-3]. These parasitic infections can cause a wide range of harm to the infected...

INTRODUCTION The integrity of the gut is fundamental in birds as the mechanisms of digestion and absorption are inherent in the physiological metabolism of the gastrointestinal tract (GIT) and cannot be manipulated 1 . Numerous infectious and non-infectious agents can damage intestinal mucosa, as well as compromise digestion and absorption 2 . Among them, coccidia infections represent one of the most important enteric diseases. Coccidiosis is an infectious...

INTRODUCTION Necrotic enteritis (NE) is an enteric bacterial disease in chickens that is caused by Clostridium perfringens type G infection. Avian NE has gained much attention recently in the post antibiotic/anticoccidial agents' era as this infection has resulted in huge economic losses of 2 to 6 billion US dollars in the global poultry industry (Lee et al., 2020). Furthermore, the recently discovered NE B-like (NetB) toxin secreted by C. perfringens type G has been...

Soybean meal (SBM) is an ingredient with a high digestibility of protein, Lys, and Met. An optimal heating process of SBM is required to eliminate antinutritional components that negatively interfere with digestion, absorption, and metabolism of nutrients. The effect of 3 commercial SBM batches were subjected to different heat treatments to evaluate its effect on growth performance and intestinal integrity. A total of 1,860 male Cobb 500 broiler chicks were vaccinated at 1d of age with a...

1. Introduction Necrotic enteritis (NE) is caused by the Gram-positive bacterium Clostridium perfringens [1], while the etiological agents of coccidiosis are Eimeria, a genus of apicomplexan parasites [2]. Both NE and coccidiosis are among the most economically significant infectious diseases facing the poultry industry causing growth retardation, morbidity, and even mortality [1,2]. With a growing number of countries having withdrawn in-feed antimicrobials for growth promotion...

The villi of the intestinal mucosa are lined by a single layer of columnar cells, comprising enterocytes, goblet and enteroendocrine cells, and various types of immune cells, each with a distinct function. Chicken gut mucosa is exposed to an enormous number of feed antigens, and pathogenic bacteria that often impair the intestinal barrier function. Ultrastructural examination of enterocytes, their organelles and other features, such as mitochondria, microvilli, and tight junctions sealing...

The antibiotic growth promoters (AGP) have been used in animal feed for decades to promote animal health and production. However, extensive use of antibiotics in animal agriculture led to increased concerns over antibiotic contamination in food and environment, and the emergence of antibiotic-resistant microorganisms. With the reduction and eventual withdrawal of...

Necrotic enteritis is the result of the overgrowth of Clostridium perfringens in the upper part of the intestines. Clostridum perfringens is a Gram-positive bacteria and forms spores that are extremely resistant to desiccation, heat, disinfectants, and UV radiation, and as a consequence, it is frequently present in poultry houses all around the world....

INTRODUCTION Coccidiosis is a major enteric disease of chickens that is caused by several distinct species of Eimeria protozoan parasites infecting different areas of the gut. Coccidiosis primarily damages epithelial integrity in the intestine decreasing nutrient utilization and resulting in an annual loss of over $3.2 billion in the poultry industry globally (1–3). With the onset of coccidiosis, Eimeria elicits a local inflammatory response in the intestine, increasing...
