Effects 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...
متن کاملEffect of Diclazuril on the Bursa of Fabricius Morphology and SIgA Expression in Chickens Infected with Eimeria tenella
The effects of diclazuril on the bursa of Fabricius (BF) structure and secretory IgA (SIgA) expression in chickens infected with Eimeria tenella were examined. The morphology of the BF was observed by hematoxylin and eosin staining, while ultrastructural changes were monitored by transmission electron microscopy. E. tenella infection caused the BF cell volumes to decrease, irregularly arranged,...
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 کاملEnhanced egress of intracellular Eimeria tenella sporozoites by splenic lymphocytes from coccidian-infected chickens.
Egress, which describes the mechanism that some intracellular parasites use to exit from parasitophorous vacuoles and host cells, plays a very important role in the parasite life cycle and is central to Eimeria propagation and pathogenesis. Despite the importance of egress in the intracellular parasite's life cycle, very little information is known on this process compared to other steps, e.g.,...
متن کاملEffect of a Mannanoligosaccharide Preparation on Eimeria tenella Infection in Broiler Chickens
The hypothesis tested was that the feeding of mannanoligosaccharides (MOS) will suppress the signs of a coccidiosis infection in broilers. Two separate experiments were performed in which part of the broilers used were infected with Eimeria tenella. In each experiment there were three treatment groups: a negative control group fed the basal diet and two infected groups fed the basal diet withou...
