Yersinia enterocolitica and Yersinia pseudotuberculosis, the two Yersinia species that are enteropathogenic for humans, are distributed worldwide and frequently cause diarrhea in inhabitants of temperate and cold countries. Y. enterocolitica is a major cause of foodborne disease resulting from consumption of contaminated pork meat and is further associated with substantial economic cost. Howeve...

Yersinia pestis, Y. pseudotuberculosis O:1, and Y. enterocolitica biogroup 1B strains carry a high-pathogenicity island (HPI), which mediates biosynthesis and uptake of the siderophore yersiniabactin and a mouse-lethal phenotype. The HPI of Y. pestis and Y. pseudotuberculosis (Yps HPI) are highly conserved in sequence and organization, while the HPI of Y. enterocolitica (Yen HPI) differs signif...

The objective of this study was to determine the effect of sampling (swab samples compared to destructive samples) on isolation rates of human pathogenic Yersinia enterocolitica from pig tonsils. Moreover, the relative efficiency of different rapid, routinely applicable isolation methods was evaluated. Therefore, swab and destructive samples from tonsils of 120 pigs at slaughter were analyzed i...

The acetone extract of the lichen Ramalina farinacea and its (+)-usnic acid constituent showed antimicrobial activity against Bacillus subtilis, Listeria monocytogenes, Proteus vulgaris, Staphylococcus aureus, Streptococcus faecalis, Yersinia enterocolitica, Candida albicans, and Candida glabrata. Norstictic acid was active against Aeromonas hydrophila as well as the above microorganisms except...

Ten epidemiologically related Yersinia enterocolitica clinical isolates were studied. Six isolates were nalidixic acid resistant (MIC > 512 microg/ml), with mutations in the quinolone resistance-determining region (QRDR) of the gyrA gene, suggesting clonal dissemination of a nalidixic acid-susceptible Y. enterocolitica strain which has acquired different mutations generating resistance to nalid...

Four recent cases of Yersinia enterocolitica infections from Florida are discussed. Two of the cases presented as acute mesenteric lymphadenitis, and the other two presented as septicemia. Three of the isolates were an uncommon serotype, O:2,3, and the fourth was serotype O:5. The increasing occurrence of Y. enterocolitica in semitropical areas of the United States is emphasized.

Yersinia enterocolitica rarely causes extraintestinal disease. A 54-year-old construction worker with chronic hepatitis C developed an axillary abscess following an injury to his finger. An aspirate from the axillary mass grew Y. enterocolitica. Direct inoculation is proposed as the mode of transmission of this classically enteric pathogen.

We report the first case of blood culture-positive Yersinia enterocolitica serotype O:8 septicemia in Japan. Y. enterocolitica serotype O:8 infection is very rare, but chromosomal DNA analysis suggested that this bacterium may persist latently in healthy carriers throughout Japan.

BACKGROUND Enteropathogenic Yersinia circulate in the pig reservoir and are the third bacterial cause of human gastrointestinal infections in Europe. In West Africa, reports of human yersiniosis are rare. This study was conducted to determine whether pathogenic Yersinia are circulating in pig farms and are responsible for human infections in the Abidjan District. METHODOLOGY/PRINCIPAL FINDING...

Yersinia enterocolitica is the cause of gastrointestinal infection in the overwhelming majority of recognized cases, although extraintestinal sites are occasionally involved. We report a case of Y. enterocolitica septicemia and empyema complicated by the adult respiratory distress syndrome. The organism was also recovered from the patient's feces by alkaline enrichment and persisted through at ...
