[Suggestions concerning serological diagnosis of echinococcosis in Poland].

It has been suggested to change the present way of serological diagnosis of echinococcosis in Poland which utilizes immunoelectrophoresis for confirmation of positive results in a screening test. Diagnostic procedure should be indicated with a sensitive test, such as indirect haemagglutination or immunoenzymatic assay, and every positive result should be verifies later using a Western-blot method in order to detect the most specific reaction with 8 kDa fraction of Echinococcus antigen. Further diferentiation of the infecting species may be accomplished with the aid of Em2 plus ELISA test which detects antibodies specific for E. multilocularis.
