摘要:
This invention relates to novel Eimeria proteins with immunogenic properties, and having lactate dehydrogendse activity as well as to DNA sequences encoding these proteins. These proteins can be administered to poultry thereby protecting the birds against coccidiosis. In addition the DNA encoding these proteins can be used for the preparation of a vector vaccine against coccidiosis.

摘要:
Purified antigenic proteins are provided which are capable of inducing in a chicken an immune response conferring protection against infection by Eimeria necatrix and/or Eimeria tenella. One protein, useful for conferring protection against E. tenella and E. necatrix, has been derived from sporocysts of E. necatrix. Monoclonal antibodies directed against the antigenic proteins have also been developed which may be used to confer upon a chicken passive immunity against coccidiosis. Further provided are nucleic acid molecules encoding the antigenic proteins as well as expression vectors containing them. Methods for producing the proteins or antigenic polypeptides having amino acid sequences included within these proteins are also provided.
摘要:
The invention is concerned with a protein having the immunological properties of Eimeria tenella which is reactive with a monoclonal antibody E. TEN 11P-2 raised against E. tenella sporozoites. The invention also relates to polypeptide fragments of this protein which can be used for immunization against E. tenella . These proteins and polypeptides can be prepared by isolation from E. tenella, by chemical synthesis or by recombinant DNA methods using the polynucleotides described herein or related sequences.
摘要:
Methods and compositions are disclosed for vaccinating warm-blooded animals against coccidiosis utilizing suspensions of excysted coccidial sporozoites in physiologically balanced medium containing water-soluble polymeric stabilizers selected from gels, gelatins, polysaccharide gums, cellulose or cellulose derivatives which extend viability or storage, additional extension of viability in storage being attained when the suspensions are finely divided and the polymeric stabilizers are hardened to form microcapsules.
