title: Dot-dye-immunoassay and dot-ELISA for the serological differentiation of acute and chronic schistosomiasis mansoni using keyhole limpet haemocyanin as antigen.
abstract: Two immunoassays, dot enzyme-linked immunosorbent assay (dot-ELISA) and dot-dye immunoassay (dot-DIA), using soluble egg antigen and keyhole limpet haemocyanin as antigens, were evaluated for the serological differentiation of 25 acute and 37 chronic patients infected with Schistosoma mansoni and 20 non-infected individuals, in comparison with ELISA. Efficiency was 92.7%, 90.0% for ELISA, dot-ELISA and dot-DIA, respectively. Dipstick dot-ELISA and dot-DIA are described and shown to be reliable cheap and simple methods for the serological differentiation of acute and chronic schistosomiasis.
