[The clinical manifestations and differential diagnosis of Yersinia hepatitis and viral hepatitis A and B].

Hepatic involvement in yersiniosis is associated with clinical symptoms of hepatitis, sometimes dominant in the clinical picture. Such cases need differentiation of yersiniosis with viral hepatitides A and B. Clinical and biochemical findings were compared for matched patients with yersiniosis-induced hepatic lesions, viral hepatitis A and viral hepatitis B verified at specific laboratory examination. This permitted introduction of differential diagnostic signs able to recognize one disease from the other.
