Identification of Infective Larva (L3) Proteins of Strongyloides Stercoralis by Immunoblot

摘要

Background: Strongyloides stercoralis is prevalent in tropical and subtropical regions worldwide. This parasite is the only nematode with the ability to multiply in its host's body via autoinfection transmission. Larvae detection in feces is difficult partly because of low egg production and also irregular larvae excretion in feces. Serologic tests (ELISA, IFA) are also diagnostic, however Strongyloides stercoralis antigens are not available as a diagnostic tool. In the present study, we analyzed filariform larva (L3) proteins of Strongyloides stercoralis by the immunoblot technique.
