In the present study, efficacy of the toltrazuril treatment for prevention of coccidiosis and necrotic enteritis was tested. Ninety-six 14-day-old commercial broiler chickens were caged and divided into eight groups (n=12), designated groups 1 to 8. Chickens of groups 1 to 6 were inoculated orally at 18 days of age with 25,000 oocysts of Eimeria tenella and(More)
The interaction between Eimeria species and Clostridium perfringens was investigated in two different necrotic enteritis (NE) models: 120-day-old broilers were used in two separate experiments consisting of six groups (n=10) each. Besides controls, chickens were infected with coccidia on study day (SD) 18 (Eimeria maxima and Eimeria acervulina (experiment(More)
The chorioallantoic membrane (CAM) of chicken embryo eggs is a suitable model for viral and bacterial infections. In the present study, a new approach for testing the pathogenesis and virulence of Clostridium perfringens and Eimeria tenella dual infections as a model using the CAM of embryonated chicken eggs was developed. For this purpose, 24 specific(More)
