[Excretion-secretion antigens from adult Dirofilaria immitis in the diagnosis of human filariasis by solid phase immunoenzyme assay].

The solid phase enzymatic immuno-assay (ELISA) was normalized for detecting antibodies against. Filaria using excretion-secretion antigens (ESA) from Dirofilaria immitis adults in a group of asymptomatic and microfilaraemic patients infected by different species of filariae (loa loa, Wuchereria bancrofti, Onchocerca volvulus, Mansonella ozzardi and Mansonella perstans), and in another group of symptomatic and aminorofilaraemic patients, temporary residents in an area with endemic loiasis. The ESA-ELISA specificity permitted the distinction between filariasic and non-filariasic patients.
