Identification of Larval-Stage Antigens of Ascaris suum Recognized with Immune Sera from Pigs

摘要

References(20) Cited-By(4) Antigens were identified from the third-stage larvae (L3) and lung-stage larvae of Ascaris suum by two-dimensional immunoblot method with antisera obtained from pigs that received chemically abbreviated Ascaris suum larval infections. Forty-seven and 13 spots were recognized as antigens from the L3 and lung-stage larvae, respectively. Their apparent molecular weight ranged from 20 to 101 kDa and their isoelectric point from 3.6 to 8.0. The present study provides a framework for further molecular cloning of those antigens and consequently leads to the development of recombinant peptide vaccines against A. suum.
