The Effects of Probiotics on Performance and Immune Response of Broiler Chickens during Coccidiosis
Coccidiosis is endemic in the commercial broiler industry and inflicts devastating economic losses to poultry operations. Probiotics may provide a potential alternative to the prophylactic use of anticoccidials in commercial production. This study evaluated the effects of probiotic applications …

Prevalencia de Coccidiosis en lechones de patio de el casco urbano de Siguate-Olancho, Honduras
La Coccidiosis neonatal es una de las enfermedades producidas por protozoarios, cuyo agente causal en la especie porcina es la Isospora Suis. Se caracteriza por una invasión aguda al intestino delgado, con frecuencia atacando animales jóvenes, produciendo destrucción de los enterositos y la …

Development of a Canine Coccidiosis Model and the Anticoccidial Effects of a New Chemotherapeutic Agent
… of this work were to develop a model for canine coccidiosis while proving that Cystoisospora canis is a true primary pathogen in dogs and to determine the efficacy of a new anticoccidial agent. A canine coccidiosis model would be useful in evaluating new anticoccidial treatments. Oral infections …

Performance and Microbial Profiles of Broiler Chickens fed Phytogenic Feed Additives or Probiotics during Coccidiosis
… out of poultry operations. Diseases such as coccidiosis are extremely costly, and typically prevented with coccidiostats and antibiotics. New regulation banning antibiotics is mandating a search for new alternatives, such as probiotics and phytogenic feed additives (PFAs). Two separate …

Development of a Turkey Coccidiosis Vaccine Candidate: an Attenuated Line of the Protozoan Parasite, Eimeria meleagrimitis
<p>Coccidiosis is an economically important enteric disease of poultry caused by protozoan parasites belonging to the genus Eimeria. Drugs are most commonly used to control coccidiosis. Widespread usage of anticoccidial drugs in the field has resulted in development of drug resistant strains and …

Bovine Coccidiosis: Dynamics of infection in grazing cattle and the potential role of stress and immunity
… FOC was not observed. A model of stress- induced coccidiosis was developed using dexamethasone and E. bovis challenge. In this model, an oral challenge of at least 500,000 sporulated E. bovis oocysts in addition to dexamethasone injection at 7 days post challenge increased subsequent FOC. Further …

The combined effects of purified fiber and dietary threonine on chick growth, and gut health, when infected with coccidiosis
… fiber and dietary Thr during an Eimeria maxima coccidiosis infection. In Experiment 1, chicks received corn/soybean meal (SBM) based diets containing 7% added silica sand (control), cellulose, or high-methoxy pectin through d 14 post-hatch. Inclusion of pectin reduced (P < 0.05) weight gain by …

Trace Element Nutriture of the Chick as Affected by Eimeria Acervulina Infection
… status of young chicks as affected by duodenal coccidiosis and by trace mineral intakes ranging from deficient to excess. The trace elements investigated were cobalt, iron, manganese, zinc and copper. Experimental coccidiosis was induced by inoculation with 2 x 10('5), 4 x 10('5) or 8 x 10('5) …

Interactions Between Nutrition and Health or Stress in Poultry
… amino acid digestibility in chicks infected with coccidiosis. The results indicated that coccidiosis infection (Eimeria acervulina) reduced MEn and amino acid digestibility in chicks and that the coccidiosis effect was influenced by diet composition, type of infection (acute v. chronic) and timing …

Effects of Marek's Disease Herpesvirus and Turkey Herpesvirus Upon Immunity to Eimeria Acervulina in Young Chickens
… infections with Marek's disease (MD) and coccidiosis in chicken flocks have perplexed investigators for years. Infection with MD herpesvirus has been shown to inhibit immunity of chicks to three species of Eimeria. Herpesvirus from turkeys (HVT) is used commercially as a vaccine against …

Impact of Dietary Beta-glucan Supplementation on Performance and Immune Response of Broiler Chickens During Challenge
Coccidiosis is a costly parasitic disease to the poultry industry with multiple prevention methods being explored to control its impact. One approach under development is the use of -glucans, which are carbohydrates from cell walls of various plant species. The first study evaluated the feeding …
