Echinococcus multilocularis: Purification and characterization of glycoprotein antigens with serodiagnostic potential for canine infection

► A large glycoprotein of Echinococcus multilocularis was newly isolated. ► The glycoprotein (Emgp-89) was specifically reacted with the sera from infected dog. ► The Emgp-89-based ELISA showed 100% sensitivity and 90% specificity. ► ELISA after pretreatment with NaIO4 and proteinase K improved the specificity.
