Use of Protein AG in an Enzyme-Linked Immunosorbent Assay for Serodiagnosis ofToxoplasma gondiiInfection in Four Species of Animals

Abstract
An enzyme-linked immunosorbent assay (ELISA) employing protein AG (AG-ELISA) as a conjugate was developed to detect anti-Toxoplasma gondiiantibodies (Ab) in experimentally infected pigs and naturally infected pigs, goats, dogs, and cats. The results indicate that AG-ELISA can be a useful method for serological diagnosis ofT. gondiiinfection in these four species of animals.
