DNA encoding the Trichinella spirals 53kD excretory/secretory antigen for use as immunodiagnostic reagents

摘要

Disclosed are DNA sequences which encode an amino acid sequence homologous to a segment of Trichinella spiralis 53 kilodalton excretory-secretory antigen, recombinant polynucleotide molecules containing the sequences, and transfer and replication of the sequences in a transformed host to produce antigens useful as immunodiagnostic reagents or vaccines specific for T. spiralis.
