Kinetics of antibody response by Dot-ELISA in rabbits immunized with adult Haemonchus contortus antigen.
Whole adult soluble extract of Haemonchus contortus as an antigen along with Freund's complete adjuvant, was used to immunize rabbits. Antisera from immunized rabbits were collected at intervals of 30, 60, 90, 120, 150 and 180 days. For the detection and titration of anti-H. contortus antibodies in these sera, Dot-ELISA was developed. Sera collected 30 days post-immunization exhibited a titre of 1:5,000 in all the rabbits except one, where a titre of 20,000 was recorded. Later, all the rabbits attained the highest titre of 40,000 at different periods of post-immunizations, which were maintained 150-180 days. These high titre sera can be of immense use in the identification and characterization of immunodominant antigens of adult H. contortus.
