Echinococcosis antigen gene (egG1Y162 antigen gene), and recombinant protein and use thereof

The present invention relates to the field of antigen gene technology, specifically to an echinococcosis antigen gene, namely egG1Y162 antigen gene and its recombinant protein and applications, wherein, the gene has a nucleotide sequence with a sequence 1. The invention obtains the echinococcosis antigen gene, namely egG1Y162 antigen gene and its recombinant protein from the granule echinococci, performs cloning, transforming and induce expression to the egg1y162 gene, the animal experiment further indicates that the egg1y162 recombinant protein vaccine has a protective effect on the infection of secondary granule echinococci to mice, becomes a candidate gene vaccine for preventing and controlling echinococcosis, and provides a new way for the development of practical vaccine.
