[Yersinia enterocolitica IHA-test (author's transl)]. / Yersinia-enterocolitica-IHA-Test.

612 serum specimens were examined for antibodies against Yersinia enterocolitica (Y.e.) with the Widal technique, and an indirect (passive) hemagglutination test. The Widal test was carried out with antigens of Y.e. serovar 0:3 and 0:9. Human erythrocytes coated with antigens of both serovarieties were used for the Y.e.-IHA-test. This test system showed higher agglutinin titres than the Widal reaction. Both methods were equivalent concerning their specificity. The Y.e. IHA-test is suitable for screening enteric diseases to determine infections caused by. Y. enterocolitica. This test is easy to set up and can be used for routine diagnostics since it can be carried out and interpreted quickly and objectively.
