A diagnostically useful 200-kDa protein is secreted through the surface pores of the filarial parasite Setaria digitata.

The excretory/secretory (ES) materials from filarial parasites form an important tool for immunodiagnosis of filariasis. We have raised monoclonal antibodies against ES proteins isolated from the medium incubated with live adult bovine filarial parasite Setaria digitata. The hybridoma were cloned and characterised with respect to the individual proteins of the ES materials.
