Abdominal angiostrongyliasis is a nematode disease produced by Angiostrongylus costaricensis, a metastrongylid parasite of wild rodents. Accidental human infection occurs through ingestion of food or water contaminated with third-stage larvae present in the mucous secretion of terrestrial molluscs. An ELISA test was standardized for detection of IgG antibodies recognizing a surface antigen prepared from female worms. Competitive absorption of sera with Ascaris suum crude antigen resulted in a test with 86% sensitivity and 83% specificity. The disease is endemic in Southern Brazil and a number of cases are diagnosed every year through anatomo-pathological examination of biopsies or surgical specimens, since no other diagnostic method is available. According to seroepidemiological studies, prevalences in two transmission foci are 29.8 and 66%, attesting to the widespread occurrence of the infection in those endemic areas.
