Detection of Cell Mediated Immune Response in Chickens Immunized with Eimeria tenella Sporozoites
The Indian poultry sector has become a major contributor to the national economy as a result of the revolutionary and scientific approaches in avian health care management. Indian poultry industry contributes nearly Rs. 9.9 billion annually to the national economy (Mohana Subramanian et al., 2010).

متن کاملImmunoglobulin producing cells in chickens immunized with Eimeria tenella gametocyte antigen vaccines
The present paper reports on the IgA, IgG and IgM antibodies secreting cells (ASC) in the spleen of chickens vaccinated with E. tenella (local isolates) gametocyte vaccine(s) by using Enzyme Linked Immunospot (ELISPOT) assay. Irrespective of the vaccine used, the number of IgG antibody secreting cells (ASC) in the spleen of orally vaccinated chickens was higher than the number of IgA and IgM AS...
متن کاملDietary Curcuma longa enhances resistance against Eimeria maxima and Eimeria tenella infections in chickens.
The effects of dietary supplementation with an organic extract of Curcuma longa on systemic and local immune responses to experimental Eimeria maxima and Eimeria tenella infections were evaluated in commercial broiler chickens. Dietary supplementation with C. longa enhanced coccidiosis resistance as demonstrated by increased BW gains, reduced fecal oocyst shedding, and decreased gut lesions com...
متن کاملBacterial Population Changes in the Ceca of Young Chickens Infected with Eimeria tenella.
Eimeria tenella, a protozoan parasite belonging to the class Sporozoa, is the etiological agent of cecal coccidiosis of chickens. This organism goes through a typical sporozoan life cycle and, with the exception ofsporulation of the oocyst, all stages occur within the host's intestinal tract. Invasion of the intestinal epithelium by sporozoites and merozoites results in considerable tissue dest...
متن کاملEffects of Artemisia annua and Foeniculum vulgare on chickens highly infected with Eimeria tenella (Phylum Apicomplexa)
BACKGROUND Intensive poultry production systems depend on chemoprophylaxis with anticoccidial drugs to combat infection. A floor-pen study was conducted to evaluate the anticoccidial effect of Artemisia annua and Foeniculum vulgare on Eimeria tenella infection. Five experimental groups were established: negative control (untreated, unchallenged); positive control (untreated, challenged); a grou...
