摘要

isolated astrovirus strain, isolated nucleotide sequence, gene construction, vector, method of producing a polypeptide encoded by a nucleotide sequence, polypeptide sequence, polyclonal and monoclonal antibodies, use of at least part of an isolated astro virus strain designated castv-3, a nucleotide sequence, or polypeptide, vaccine for immunization against growth depression in a bird, methods of vaccinating a bird against castv-3 and diagnostic testing for the detection of type 3 chicken astrovirus in samples. of birds and diagnostic kit. A new astrovirus called type 3 chicken astrovirus has been isolated and characterized. The nucleotide sequences and polypeptide sequences of 5 of these astroviruses are provided using both the same and the astrovirus isolated in test kits and vaccines.
