摘要

ASTROVIRUS CEPA ISOLATED, NUCLEOTIDE SEQUENCE ISOLATED, GENE CONSTRUCTION, VECTOR, METHOD OF PRODUCTION OF A POLYPEEPTIDE ENCODED BY A NUCLEOTIDE SEQUENCE OF POLYEPTIDE, A POLYTEPTONOUS ANTIBODY, A POLYTHROUSAL MONO DESIGNATED CASTV-3, A NUCLEOTIDE SEQUENCE, OR A POLYPEPTIDE, VACCINE FOR IMMUNIZATION AGAINST GROWTH DEPRESSION, METHODS OF VACCINATION OF AN AVE AGAINST CASTV-3 AND A DIAGNOSTIC TEST FOR THE DETECTION OF THE TASTRY OF TESTATION OF BIRDS, AND, DIAGNOSTIC KIT. A new astrovirus called chicken astrovirus type 3 has been isolated and characterized. The nucleotide sequences and polypeptide sequences of 5 of these astroviruses are provided with uses of the same and the astrovirus isolated in test kits and vaccines.
