原始语种摘要: Apicomplexan parasites of the genus Eimeria are widespread in poultry flocks and if present in sufficient numbers can cause the intestinal disease coccidiosis. For many years, the disease has been controlled either by incorporating drugs in the feed (prophylaxis) or by immunization with live parasites (vaccination). Efficacy of anticoccidial drugs has been compromised by the acquisition of resistance which has been documented for all drugs introduced including those most widely used, the ionophorous antibiotics. A consequence of limited efficacy is that these drugs permit some parasite development thus allowing the acquisition of immunity. Combined with improvements in management, this may explain the continued use of drugs for the control of coccidiosis in broiler and turkey production....
