Evaluation of the dot enzyme-linked immunosorbent assay in diagnosis of leishmaniasis

Human sera were collected from twenty patients of parasitologically proven cutaneous leishmaniasis, 35 cases of schistosomiasis mansoni and ten normal control sera. The antileishmanial antibodies were detected by the dot enzyme-linked immunosorbent assay (dot ELISA). The results showed that the dot ELISA had high sensitivity. However, there was a marked deal of cross reactivity with the antisera of schistosomiasis mansoni infected patients, particularly those with splenomegaly and ascites.
