We evaluated a recombinant antigen (OC 3.6 cDNA) expressed in pMAL TM vector for the diagnosis of onchocerciasis in children living in an endemic focus of forest-type onchocerciasis in Nigeria. Using the Western blot with the maltose-binding fusion protein as antigen, 91 per cent of mf-positive children and 24 per cent of endemic normal children were positive. Furthermore, age was not a limitation to the assay. The practical limitations of the assay for field diagnosis of onchocerciasis is discussed.
