A prospective study was undertaken on 54 patients with an apparently idiopathic first attack of acute anterior uveitis. Blood samples were assayed for antibodies to Yersinia enterocolitica and Yersinia pseudotuberculosis, and tested for HLA type. Thirteen patients were found to have serological evidence of recent yersinia infection, eight with Y. enterocolitica and five with Y. pseudotuberculos...
The genus Yersinia includes three human pathogens, of which Yersinia pestis is responsible for >2,000 illnesses each year. To aid in the development of detection assays and aid further phylogenetic elucidation, we sequenced and assembled the complete genomes of 32 strains (across 9 Yersinia species).
We developed a 4-h nested polymerase chain reaction assay that detected a region of the plasminogen activator gene of Yersinia pestis in 100% of 43 Y. pestis strains isolated from humans, rats, and fleas yet was unreactive with the closely related species Yersinia enterocolitica and Yersinia pseudotuberculosis.

Multilocus enzyme electrophoresis was used to analyze 244 strains of nine Yersinia species isolated from the environment, animals, and humans at 18 genes encoding metabolic enzymes. All 18 enzymes were polymorphic. Among the 137 electrophoretic types (ETs) distinguished, the mean allelic diversity per locus was 0.531. Yersinia frederiksenii ETs were divided into three major clusters that were s...
Consumption of meat contaminated with Yersinia pestis can cause oropharyngeal plague in humans. Existing microbiological media designed for selective detection of Y. pestis in food are not satisfactory for that purpose. Expression of genetic determinants in Yersinia species including low calcium response (Lcr), colony size, crystal violet (CV) binding, Congo red (CR) uptake, autoagglutination (...
The genus Yersinia includes species with a wide range of eukaryotic hosts (from fish, insects, and plants to mammals and humans). One of the major outer membrane proteins, the porin OmpC, is preferentially expressed in the host gut, where osmotic pressure, temperature, and the concentrations of nutrients and toxic products are relatively high. We consider here the molecular evolution and phylog...
Yersinia spp. are animal pathogens, some of which cause human disease. We sequenced 10 Yersinia isolates (from six species: Yersinia enterocolitica, Y. fredericksenii, Y. kristensenii, Y. pestis, Y. pseudotuberculosis, and Y. ruckeri) to high-quality draft or complete status. The genomes range in size from 3.77 to 4.94 Mbp.
Toll-like receptor signaling and subsequent activation of NF-κB- and MAPK-dependent genes during infection play an important role in antimicrobial host defense. The YopJ protein of pathogenic Yersinia species inhibits NF-κB and MAPK signaling, resulting in blockade of NF-κB-dependent cytokine production and target cell death. Nevertheless, Yersinia infection induces inflammatory responses in vi...
The existence of enterobacterial common antigen in Yersinia enterocolitica and its absence in Brucella abortus were utilized in an attempt to provide a method to distinguish Brucella infections from infections with cross-reacting Yersinia. The indirect hemagglutination test was employed for this purpose. In experimental laboratory animals, the presence of anti-enterobacterial common antigen was...
