Yersinia Enterocolitica Infection Complicated by Glomerulonephritis

Abstract

A case of mild glomerulonephritis in a 24-year-old man with clinical and immunohistological findings associated with Yersinia enterocolitica serotype 3 infection is described. The role of IgA in the pathogenesis of glomerulonephritis associated with mucosal infection is briefly discussed. Although attempts to demonstrate Y. enterocolitica 3 antigen in the biopsy specimen were unsuccessful, the glomerular deposits of immunoglobulins and complement suggest immune pathogenesis.
