It is well-known that cirrhosis is a predisposing factor to Yersinia septicemia. This study includes 73 cirrhotics and shows a high number of positive serologic tests (47/73 : 64.4%). However, there is no correlation with clinical features or bacteriological findings. The most frequent serotypes, i.e. pseudotuberculosis IV and enterocolitica 0:9, differ from those which are usually found in Yersinia septicemias. Iron overload in cirrhosis, increased intestinal load of gram-negative bacilli and possible latent bacteremia may partly explain these results. However, the role probably played by as yet poorly known cross-reactions between Yersinia and other pathogens (Shigella, E. Coli...) must be underscored. The authors conclude that slightly positive, stable, serodiagnostic tests have little meaning in cirrhotics.

Yersinia pseudotuberculosis is a rare cause of disease in humans, the most common manifestation being mesenteric lymphadenitis accompanied by abdominal pain and fever. A septicemic form of Yersinia pseudotuberculosis infection has been reported only rarely. It is usually seen in patients with underlying disorders such as diabetes, hepatic cirrhosis or iron overload. Fifty-four cases of septicemic infection were found in the literature. The earlier published cases are reviewed, and four cases occurring in Finland during the period February to June 1992 are reported.

A 40-yr-old buddhist monk was admitted to the hospital with abdominal pain, fever, and confusion. He had a history of drinking untreated mountain spring water in his temple, and experienced the above symptoms for several days before admission. In past medical history, he had suffered from hepatic cirrhosis. Yersinia pseudotuberculosis was isolated from his blood and ascitic fluid. The mountain spring water that he had ingested was cultivated and Y. pseudotuberculosis was also isolated. For identification of pathogenic Y. pseudotuberculosis, each isolate from the three sources (blood, ascitic fluid, and drinking water) was also analysed for the inv gene for Y. pseudotuberculosis and the virF gene for virulent plasmid by PCR. All strains were positive for both the virF and the inv genes and also positive for autoagglutination test. For relationship study, each isolate from the three sources was also analysed with serotyping and restriction endonuclease analysis of virulence plasmid DNA (REAP) using BamHI. All belonged to the serotype 4b and REAP pattern D. Thus, all these findings supported that the mountain spring water was the source of the Y. pseudotuberculosis infection in this case.

Yersinia pseudotuberculosis is a Gram-negative zoonosis which occasionally infects humans via ingestion of contaminated food and water, and typically causes a self-limiting gastrointestinal tract infection. Patients who are immunocompromised, have haemochromatosis or liver cirrhosis are more likely to develop serious complications such as bacteraemia. We present the case of a 76-year-old man with fever and an acutely tender, swollen right knee. Blood cultures were positive for Y. pseudotuberculosis, and 16s ribosomal PCR analysis of his knee aspirate confirmed septic arthritis. He was treated with intravenous ceftriaxone and made an excellent recovery following knee washout. Interestingly, our patient did not have any of the classic risk factors described in the literature, or history of exposure to the pathogen to explain his diagnosis. To our knowledge, this is only the second confirmed case of Y. pseudotuberculosis bacteraemia with septic arthritis, and the first to involve the knee joint.
