A case of bacteremia caused by Yersinia enterocolitica serotype 3, biotype 4, is described in a 79-year-old man with an aortic bifurcation prosthesis. He died, in spite of antibiotics, from massive intraabdominal bleeding at the infected suture site. Yersinia, like Salmonella, seems to have a special affinity for damaged endovascular tissue, although more observations will be needed to support this hypothesis.

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.

Bacteraemia caused by Yersinia enterocolitica was associated in a 60-year-old diabetic man with right upper-quadrant abdominal tenderness and abnormal liver function tests. Biopsy of the liver demonstrated granulomas with acute necrosis. To the authors' knowledge, this is the first report of granuloma formation in the human liver associated with this infection. Yersinia enterocolitica should therefore be added to the list of organisms associated with granulomatous hepatitis in human beings.

A patient with Yersinia enterocolitica endocarditis was seen with bacteremia, valvular vegetation, new heart murmur, and septic embolism. To our knowledge, this is the first reported case of Y enterocolitica infectious endocarditis and is yet another clinical manifestation of disease produced by this organism.

Newly hatched chicks subcutaneously injected with or orally exposed to Yersinia enterocolitica were colonized in the gastrointestinal tract by this bacteria. Colonization did not take place when chicks were exposed to less than 10(8) colony-forming units. In monoxenic chicks, major colonization was detected in the crop, ceca, and cloaca; fewer numbers colonized other regions of the gastrointestinal tract, and there was little evidence of bacteremia. None of the chicks exhibited clinical signs, although colonization was demonstrated throughout the gastrointestinal tract over the 28-day test period. Prior colonization by native gut microflora prevented subsequent colonization by Y. enterocolitica in holoxenic chicks.

During an 8.5-year period (1974 to 1982), 56 Yersinia enterocolitica isolates from patients residing mainly in the New York City area were studied. Evaluation of these isolates revealed a marked increase in bacteremic episodes caused by strains of serogroups of O:3 and O:5,27 and the overall emergence of serogroup O:3, biotype 4, phage type 9b Y. enterocolitica. Of the serogroup O:3 stool isolates, 59% (19/32) were recovered from patients in their first year of life. One of these subjects had concurrent serogroup O:3 bacteremia. The apparent establishment of serogroup O:3 Y. enterocolitica in urban communities raises the potential for widespread outbreaks of disease caused by these strains.

Infections of the cardiovascular system, besides involving both natural and prosthetic heart valves, vascular grafts, and indwelling venous and arterial cannulas, may cause mycotic aneurysms. The latter frequently complicate endocarditis; however, they may occur as isolated phenomena. Enterobacteriaceae are uncommon etiologic agents in vascular infections; however, a patient is reported who presented initially with a bacteremia due to Yersinia enterocolitica biogroup 4 and despite antimicrobial therapy developed a mycotic aneurysm of the left internal carotid artery. Clinical manifestations, pathogenesis, and treatment of yersiniosis are reviewed.

A 71-yr-old diabetic patient was evaluated because of right upper quadrant pain. He was found to have a large hepatic abscess secondary to Yersinia enterocolitica infection. He lacked clinical evidence of bacteremia or gastrointestinal infection. It is postulated that Yersinia enterocolitica reached the liver through the portal system from an inapparent intestinal infection. This is the first reported case of a liver abscess secondary to Yersinia enterocolitica without evidence of systemic infection.

We report an unusual observation of Yersinia enterolitica (YE) bacteremia with subcutaneous with subcutaneous abscesses on the scalp and, by gradual extension, cerebritis in a diabetic patient. All clinical signs disappeared after surgical drainage of the abscesses and protracted antibiotherapy. The well-known affinity of YE for iron led us to demonstrate an unrecognized hemochromatosis.

Yersinia enterocolitica, a gram-negative coccobacillus, comprises a heterogeneous group of bacterial strains recovered from animal and environmental reservoirs. The majority of human pathogenic strains are found among distinct serogroups (e.g. O:3, O:5,27, O:8, O:9) and contain both chromosome- and plasmid (60 to 75 kb)-mediated virulence factors that are absent in "avirulent" strains. While Y. enterocolitica is primarily a gastrointestinal tract pathogen, it may produce extraintestinal infections in hosts with underlying predisposing factors. Postinfection sequelae include arthritis and erythema nodosum, which are seen mainly in Europe among patients with serogroups O:3 and O:9 infection and HLA-B27 antigen. Y. enterocolitica is acquired through the oral route and is epidemiologically linked to porcine sources. Bacteremia is prominent in the setting of immunosuppression or in patients with iron overload or those being treated with desferrioxamine. metastatic foci following bacteremia are common and often involve the liver and spleen. Of particular concern is blood transfusion-related bacteremia. Evidence has accumulated substantiating the role of Y. enterocolitica as a food-borne pathogen that has caused six major outbreaks in the United States. The diagnosis of Y. enterocolitica gastroenteritis is best achieved through isolation of the bacterium on routine or selective bacteriologic media. When necessary, serogrouping, biogrouping, and assessment for plasmid-encoded virulence traits may aid in distinguishing virulent from "avirulent" strains. Epidemiologically, outside of identified food-borne outbreaks, the source (reservoir) of Y. enterocolitica in sporadic cases is speculative. Therefore, prevention and control measures are difficult to institute.
