IntroductionThere have been only modest improvements in the 90% survival rate at one year after heart transplantation since 1990s. This is largely due to antibody mediated rejection, cardiac allograft vasculopathy, malignancy, and immunosuppressive complications such as infection. Here, we present a case of disseminated Yersinia four years orthotopic transplant.Case ReportA 68 old gentleman wit...
The bacteria Yersinia pestis is the etiological agent of plague and has caused human pandemics with millions of deaths in historic times. How and when it originated remains contentious. Here, we report the oldest direct evidence of Yersinia pestis identified by ancient DNA in human teeth from Asia and Europe dating from 2,800 to 5,000 years ago. By sequencing the genomes, we find that these anc...
The homogeneous recombinant mammalian protein tyrosine phosphatase 1B (PTP1B) and Yersinia protein tyrosine phosphatase (PTPase) are inactivated by a series of low-molecular-weight S-nitrosothiols. These compounds exhibited different inhibitory activities in a time- and concentration-dependent manner with second-order rate constants (k(inact)/K(I)) ranging from 37 to 113 M(-1) min(-1) against m...

Enteropathogenic species Yersinia pseudotuberculosis and enterocolitica are of great importance worldwide due to their ability survive preserve pathogenic properties in biotic abiotic environments. They can cause sporadic flare-up diseases. Therefore, it is extremely important use modern methods diagnosing diseases caused by these pathogens.
 The article analyzes the laboratory diagnostics...
Suppression of the host defense is one of the hallmarks of Yersinia enterocolitica infection. This enteric pathogen resists phagocytosis and interferes with macrophage functions from an extracellular localization (oxidative-burst generation and tumor necrosis factor alpha production). In this study, we investigated the fate of the Y. enterocolitica-infected macrophage. We found that murine J774...
Twenty two patients were followed up for a mean of 10.7 years after acute yersinia arthritis. Their clinical course, agglutination antibodies, antibodies against plasmid coded yersinia proteins, and laboratory parameters of inflammation were analysed. The clinical findings were unremarkable. Serum agglutinating antibodies against Yersinia enterocolitica were not found in any patient. Ten patien...
A 13-year-old patient developed severe shock due to administration of a Yersinia enterocolitica-contaminated red blood cell concentrate. Y. enterocolitica (serotype O:9, biotype II) was cultivated from the residual blood in the blood bag and from a stool sample of the blood donor. In the donor's plasma immunoglobulin M (IgM), IgA, and IgG antibodies against Yersinia outer proteins (YopM, -H, -D...
To develop an effective method to isolate an injured pathogenic Yersinia enterocolitica O:8 organism from environmental samples, we compared the isolation of freeze-injured and non-injured Y. enterocolitica O:8 and found that the isolation was more successful when immuno-magnetic separation (IMS) with anti-Y. enterocolitica O:8 antibody was used. Plating onto cefsulodin-irgasan-novobiocin (CIN)...
The passive intestinal permeability of patients with yersinia triggered reactive arthritis was studied using different sized polyethylene glycols (PEGs) contained in a mixture of PEG 400 and PEG 1000. The investigation was carried out at least one year after the onset of yersinia infection, and patients had neither acute gastrointestinal nor joint symptoms. The control groups included patients ...
