Increasing of serum nitric oxide metabolites in chicken Eimeria infection
In order to determine the involvement of nitric oxide in the pathogenesis of coccidiosis induced by Eimeria, 30 chickens were challenged with mixed sporulated oocysts of four species of Eimeria (E. acervulina, E. maxima, E. necatrix, and E. tenella) at 26 days of age. There was an increasing of oocyst shedding in the infected birds at 6, 10 and 14 days post-infection. Histopathological examinat...
متن کاملThe effect of administration of anti-coccidial drugs on oocyst shedding and performance in experimental coccidiosis in broiler chickens
Abstract: Coccidiosis is one of the major parasitic diseases of poultry. In this study, to compare the effects of coccidiostatic drugs on fecal oocyst shedding and body weight gain of coccidi-infected broiler chickens, 180 one day old Ross 308 broiler chicks were randomly assigned to four treatments.

متن کاملEvaluation of Eimeria oocyst whole antigen vaccine and the enhancive effect of probiotic on broilers
Chicken coccidiosis has great economic impacts on poultry industry. The present study was conducted to evaluate the effect of feeding probiotic (Biopellt-s) as well as Eimeria oocyst whole antigen vaccine by subcutaneous and intraperitoneal routes on body weight gain, lesion score, oocyst output, and phagocytic activity. One-day old broiler chicks were divided into seven equal groups (50 chicks...
متن کاملInfluence of Pediococcus-based probiotic on coccidiosis in broiler chickens.
Coccidiosis is the major parasitic disease of poultry and is caused by the apicomplexan parasites Eimeria. Drugs and live vaccines are the 2 main control measures of the disease; however, due to increasing concerns with prophylactic drug use and the high cost of vaccines, alternative control methods are needed. Recent evidence that various dietary and live microbial supplements can influence ho...
