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 Vaccination against coccidiosis in broilers has become an increasingly important part of a global prevention strategy against the disease. Not only it is an effective treatment against the clinical disease, but it also represents a clear improvement in zootechnical results when vaccines are rotated with classic anticoccidial programmes. There are several studies in HIPRA’s Area Coccidia that show and explain these improvements. ...

Coccidiosis is an important health problem in broilers, caused by infection with a highly contagious intestinal parasite of the genus Eimeria. Anti-coccidial drugs are widely used for the prevention of coccidiosis in broilers. However, multi-resistance coccidia is a potential threat to poultry production. Solid-state fermented products produced from B. licheniformis not only contain B. licheniformis spores but also have B. licheniformis derived...

I. INTRODUCTION Anticoccidials remain an essential tool in the prevention and control of coccidiosis, which is still one of the most important diseases contributing to gut health disorders. Many anticoccidials have been available for use for considerable periods of time. Monimax® (nicarbazin/monensin) is a novel coccidiostat for coccidiosis control in broilers. II. METHOD The efficacy of nicarbazin/monensin (Monimax® supplied by...

INTRODUCTION Avian coccidiosis is caused by protozoa of genus Eimeria, which belongs to family Eimeriidae and has multiple species with complex life cycle stages (Abbas et al., 2015, 2019; Khater et al., 2020). Eimeria species mostly affect bird intestines and cause bloody diarrhea, poor feed conversion ratios, and high mortality. Among all Eimeria species, E. tenella and E. necatrix are the most pathogenic, causing high mortality in chickens. Naturally, coccidian oocysts are...

I. INTRODUCTION Coccidiosis is caused by Apicomplexa protozoa of the family Eimeriidae. In poultry, most species responsible for coccidiosis belong to the genus Eimeria, which infect various sites in the intestine. Coccidiosis is recognized as one of the most common and economically important diseases in broilers, with an estimated $16,7 billion in losses globally per year. The average cost of coccidiosis per chicken produced is estimated to be $0.21 (Blake et al.,...

INTRODUCTION Consumption of poultry meat has increased significantly in the United States and currently ranks as the highest consumed among meat species (National Chicken Council, 2020). With increasing chicken meat consumption, greater number of broilers are being raised and processed. Foodborne pathogens Salmonella and Campylobacter are commensals in broiler gastrointestinal tract and, in most cases, do not cause any disease in the birds. Current poultry processing system...

Introduction The impressive genetic improvement of poultry growth rate has led to a modern bird with a very low feed conversion rate (FCR), high average daily gain (ADG) and low mortality. Unfortunately, this fast growth rate is often directly linked with digestive problems, such as bacterial enteritis (BE) or dysbacteriosis and even necrotic enteritis (NE). These intestinal health problems have significantly increased since the ban on meat and bone meal and the ban of...

1. Introduction Coccidiosis is a worldwide disease caused by the Apicomplexa protozoa of Genus Eimeria [1]. This parasitic disease causes economic losses in poultry industry due to malabsorption, reduced weight gain (explained by a reduced feed intake and as well as nutrient absorption), increased mortality and the use of anticoccidial drugs and vaccines [2, 3] and remains as a major issue for poultry producers in a large number of countries including USA [4], costing for the...

Introduction Coccidiosis caused by the apicomplexan protozoan of genus Eimeria (E) is a common and costly diseases associated with poultry production across the world. 1,2 There are several species of chicken coccidia, i.e., E. maxima, E. mitis, E. necatrix, E. praecox E. tenella, E. acervulina, E. hagani, E. mivati and E. brunetti. Among the listed species, E. maxima, E. tenella, and E. acervulina are the most common species. 3-5 The spread of the disease is...

The on-going battle against African Swine Fever and Covid-19 have caused major challenges globally affecting both food production and food security. This has been very evident in swine production, as most top pork producers and exporters were affected. Spain, being the top pork exporter, was among the first countries to be hit by the Covid-19 pandemic causing disruptions in pork supply not only to its exports but also affecting domestic supply in EU as well. This has also significantly...

CLINICAL AND SUBCLINICAL DISEASE Necrotic enteritis (NE) due to Clostridium perfringens is a disease of chickens (broilers, broiler breeders, commercial layers) and turkeys (Opengart and Songer, 2013). NE most often is diagnosed when it results in mortality and the presence of the gross lesion of a roughened-appearing mucosal surface of the small intestine at necropsy. However, the greatest economic loss to poultry producers may be due to the subclinical form of NE, which causes...

INTRODUCTION The United Nations estimates that there will be more than 9 billion people on the planet by the year 2050 (Roberts, 2011); thus, the world population will be 32% higher than that in 2006. In addition, the meat consumption per person per year is predicted to increase by 26% in the same period and will primarily comprise chicken consumption (FAO, 2010; OECD-FAO, 2010). Because of increasing concerns regarding antimicrobial resistance (Gadde et al., 2017b), growing...
