Hypoderma lineatum antigen and anti-Przhevalskiana silenus antibodies: cross-reactivity and antibody kinetics in naturally infested goats.
To evaluate the cross-reactivity between Hypoderma lineatum antigen and anti-Przhevalskiana silenus antibodies six protocols with different concentrations of antigen and different dilutions of sera and conjugate were applied. The highest cross-reaction between the H. lineatum antigen and the anti-P. silenus antibodies is given by 2 micrograms/ml of antigen concentration, 1:400 of serum and 1:10,000 conjugate dilution. The study on the kinetic development of antibodies in goats naturally infested by P. silenus and the natural course of infestation pointed out the existence of a good correlation between individual antibody kinetics and the natural evolution of the cycle of infestation. The highest antibody concentration may be registered from October through November, coinciding with the end of the migration fo the larvae inside the animal's body. In our condition, this period can be considered as a favorable sampling period for immunodiagnosis and immunoepidemiological studies of goat warble fly infestation.
