[Anticoccidial vaccines. Review and perspectives].
Coccidioses are a major problem for the poultry industry. Currently, the diseases are controlled by drug chemoprevention, but the development of chemoresistant strains has for several years incited investigators to search for a vaccine. Several methods were investigated: oocyst administration at low and controlled doses, administration of strains which had been attenuated by physical or biochemical means, immunization with extracted or recombinant antigens. For some years to come genetically selected precocious live strains of Eimeria which are now commercially available will be useful as vaccines; but in the future, genetically engineered antigens will provide new opportunities for a successful vaccination.
