Yersinia agglutinins and—when suitable samples were available—also cultural and histological evidence of Yersinia infections have been searched for from 400 hospital patients during the period 1965–70 at Lappeenranta, Finland. In 31 of them immune responses compatible with infections caused by Yersinia pseudotuberculosis (YP) serotypes I, II, III or V or Yersinia enterocolitica (YE) serotypes 3 or 9 were found. In seven patients the diagnosis was confirmed by cultural or histological findings. YE serotype 9 was involved in 20 cases. Of the 31 patients 19 had disease states commonly regarded as immunological late effects of bacterial infections. Such states included erythema nodosum, temporary arthritides or arthralgias and also pulmonary changes resembling sarcoidosis. The joint symptoms met in children were indistinguishable from so‐called benign aseptic arthritis. One patient had a typical Löfgren's syndrome.
