BACKGROUND Coccidiosis of domestic fowl, caused by species of the Genus Eimeria, is responsible for important economic losses in poultry production. Because different species and/or strains can vary in pathogenicity and other biological parameters, their precise characterization is important for epizootiological studies. METHODS Fifty samples from litter, whole intestinal tract and feces were...
post inoculation. Across all isolates there was a linear improvement in performance and decrease in coccidiosis lesions. Within all categories there were not significant differences between the NMI and N125 except for E. acervulina lesion scores (NMI 0.0 and N125 0.4). All other treatments and categories were significantly different. Feed conversions were NMU 1.447, NMI 2.594, N36 1.956, N72 1....
The objective of this study is to assess the ability of some major components of essential oils (EOs) to destroy Eimeria oocysts in vitro and to find out how the mechanism of action involved in this oocysticidal effect works. The methodology used was as follows: A screening of the oocysticidal activity of eight EO components was carried out in a liquid medium. The release of substances absorbin...
In 1910, H. B. Fantham described the life cycle of a coccidian parasite in birds. Fantham was a parasitologist at Cambridge University in the United Kingdom working for an enquiry into diseases affecting the red grouse. Despite the growing importance of the poultry industry and the realization that coccidiosis was an important disease of the fowl, little further work was carried out in the Unit...
A purified recombinant protein from Eimeria acervulina (3-1E) was used to vaccinate chickens in ovo against coccidiosis both alone and in combination with expression plasmids encoding the interleukin 1 (IL-1), IL-2, IL-6, IL-8, IL-15, IL-16, IL-17, IL-18, or gamma interferon (IFN-gamma) gene. When used alone, vaccination with 100 or 500 mug of 3-1E resulted in significantly decreased oocyst she...
Avian coccidiosis is caused by several distinct species of Eimeria protozoa and is the major parasitic disease of poultry of economic importance. As an alternative strategy to control avian coccidiosis without using prophylactic medications, we have investigated the efficacy of inducing passive immunity against coccidiosis by orally feeding hyperimmune IgY antibodies. In this study, a commercia...
Parasitism in food animal is of great economic importance. Coccidiosis is one of the gastrointestinal parasites that have a high detrimental effect on the sheep industry. A two and a half year-old ram was brought from the northern part of Nigeria into the University Teaching and Research Farm, Federal University of Agriculture, Abeokuta, Nigeria on the 30th December, 2010. About two weeks later...

None of anticoccidial vaccines (Trivalent TAM™, monovalent Neca™ and imported pentavalent Paracox(®)-5) contain Eimeria brunetti in Japan, which has not been regarded as a cause of coccidiosis, because of its low prevalence. However, we have recently reported the evidence of a high nationwide prevalence of this species. In this report, we describe the characteristics of E. brunetti which have n...
Gastrointestinal tract is one of the organ systems which infected by different pathogenic organisms specifically predilection sites for parasites (helminthes and protozoa) absorb nutrient predispose to another infection. The aim this review was provide an overview published information regarding epidemiology diagnostic approaches chicken helminthes infection coccidiosis. disease main constraint...
