Control of Avian Coccidiosis: Future and Present Natural Alternatives
Numerous efforts to date have been implemented in the control of avian coccidiosis caused by the Eimeria parasite. Since the appearance of anticoccidial chemical compounds, the search for new alternatives continues. Today, no product is available to cope with the disease; however, the number of products commercially available is constantly increasing. In this review, we focus on natural product...

متن کاملEndometrial coccidiosis.
This report describes a case of granulomatous endometritis caused by coccidiosis in an immunologically uncompromised 63 year old patient. The glandular epithelium of the endometrium contained numerous intracytoplasmic cysts, corresponding to periodic acid Schiff positive and methenamine silver negative sporoblasts. The endometrial glands revealed reactive phenomena, such as eosinophilic and squ...
متن کاملEffects of immunosuppression on avian coccidiosis: cyclosporin A but not hormonal bursectomy abrogates host protective immunity.
The effects of cyclosporin A (CsA) treatment and hormonal bursectomy on Eimeria tenella infection of chickens were investigated to evaluate the role of humoral antibody and cell-mediated immunity (CMI) in the host protective immunity to an intestinal protozoan disease, coccidiosis. Hormonal bursectomy had no significant effect on the host response to E. tenella. CsA treatment had a differential...
متن کاملImmunogenic characterization of a tissue culture-derived vaccine that affords partial protection against avian coccidiosis.
The immunogenicity of a tissue culture-derived vaccine generated from an Eimeria tenella-infected cell line in a serologically defined bird line, and the ability to confer protection against homologous challenge in young chicks was examined. The cell line, SB-CEV-1/F7, was infected with E. tenella sporozoites and the resulting 72-h postinfection cell-free supernatants were adjuvanted and used t...
