Antibody response to feeding by the horn fly, Haematobia irritans irritans (L.), was measured in naturally infested cattle as well as in controlled infestations. Humoral antibody level was not correlated with fly abundance in natural infestations. Correlations between the antibody response and fly abundance were extremely variable among animals. Antibody response to horn fly salivary antigens peaked within 4 wk after fly abundance reached 150 flies per animal. In controlled infestations, antibody response was weak during an initial exposure to 200 flies per animal, but increased after flies were removed from the cattle. Horn fly salivary antigen may have an immunomodulatory effect on the host.
在自然感染的牛以及受控感染的情况下,测定了牛对角蝇(Haematobia irritans irritans (L.))叮咬的抗体反应。在自然感染中,体液抗体水平与蝇的数量无关。动物之间抗体反应与蝇数量之间的相关性变化极大。对角蝇唾液抗原的抗体反应在每头动物的蝇数量达到150只后的4周内达到峰值。在受控感染中,最初每头动物接触200只蝇时抗体反应较弱,但从牛身上移除蝇后反应增强。角蝇唾液抗原可能对宿主具有免疫调节作用。
