Evaluation of Antibody Response to Various Developmental Stage Specific Somatic Antigens of Paramphistomum epiclitum in Goats
Electrophoretic analysis of various developmental stage specific somatic antigens of Paramphistomum epiclitum (Digenea: Paramphistomidae), namely, metacercariae (McAg), immature intestinal flukes (ImIAg), immature ruminal flukes (ImRAg), and adult flukes (AAg), was done by native polyacrylamide gel...
