The enzyme-linked immunoelectrotransfer blot (EITB) assay detects antibody bands against seven T. solium glycoprotein antigens (GP50, GP42-39, GP24, GP21, GP18, GP14, and GP13) [23] and is the reference serological test for porcine cysticercosis due to its high initially reported levels of sensitivity and specificity (99% and 100%, respectively) [24]. The gene discussed is ERVW-1; the disease is cysticercosis.
