Abstract

The filarial parasite of cattle, Onchocerca gibsoni, has been used to establish procedures of antigen identification with a view of applying these techniques to studies on human filarial parasites. Emphasis has been placed on methods suitable for use with small numbers of parasites. Microfilariae (mf) of O. gibsoni were extracted from nodular worms, purified and 125I-labeled using IODO-GEN in solid-phase. Radioactivity was shown to be confined to the cuticle of sectioned mf using the technique of electronmicroscope autoradiography. Radiolabeled mf were analysed by two-dimensional gel electrophoresis. Autoradiographs of 125I-labeled proteins of O. gibsoni mf were relatively complex, there bei..
