Combined application of enzyme-linked immunosorbent assay (ELISA) and indirect haemagglutination test (IHA) as a useful tool for the diagnosis and post-operative surveillance of human alveolar and cystic echinococcosis.
A combined application of enzyme-linked immunosorbent assay (ELISA) and indirect haemagglutination test (IHA) for the diagnosis and post-operative surveillance of human alveolar and cystic echinococcosis is described. Since January 1985 each serum sample submitted for the detection of specific antibodies was examined with both an ELISA using Echinococcus multilocularis antigen (EmELISA) and an IHA using E. granulosus antigen (EgIHA). In the course of our study altogether 72 human cases of Echinococcus infections were diagnosed. All 16 cases of alveolar echinococcosis (= 100%) and 48 out of 56 cases of cystic echinococcosis (= 86%) were revealed as Echinococcus infection at least in one of the two tests. Although crude antigens were used in both, EmELISA and EgIHA, species-specific diagnosis was achieved in 57 (= 89%) of 64 cases of the infections with E. multilocularis or E. granulosus. The diagnostic value of EmELISA and EgIHA for the post-operative surveillance is demonstrated by the follow-up of the immune response of one case of alveolar and three cases of cystic echinococcosis.
