Abstract: | Cross-reactivity between Hypoderma lineatum antigen and anti-Przhevalskiana silenus antibodies has been demonstrated by an ELISA technique. To evaluate the applicability of a commercial ELISA kit for the immunodiagnosis of goat warble fly infestation, different dilutions of serum and conjugate were tested, the development of antibody to P silenus in naturally infested goats was studied, and the results were compared with an ELISA technique using an antigen extracted from the first instar larvae of H lineatum. The best results were obtained with a serum dilution of 1:50; with both techniques the highest antibody concentration were recorded in October, November and December. In view of the confirmed cross-reactivity between H lineatum antigen and anti-P silenus antibodies, and the simplicity and rapidity of the assay, the commercial ELISA kit can be considered as a useful tool for the diagnosis of goat warble fly infestation. |
