Yersinia spp. were isolated from 34 of 500 birds representing nine species. The highest isolation rate, 5 of 21 (23.8%), was found in blue magpies (Cyanopia cyanus), followed by pheasants (Phasianus colchicus tohkaidi), 5 of 33 (15.2%); gray starlings (Sturnus cineraceus), 6 of 57 (10.5%); tree sparrows (Passer montanus), 1 of 14 (7.1%); bulbuls (Hypsipetes amaurotis), 4 of 57 (7.0%); crows (Co...

Yersinia entercolitica endocarditis has rarely been described before. This is the first report of prosthetic valve Yersinia enterocolitis endocarditis, complicated by infected brain embolization. The patient, however, completely recovered after 6 weeks of combined therapy with ceftriaxone and gentamicin.

The ability of Yersinia enterocolitica O3, grown at 25 degrees C, to promote cross-immunity to Y. pestis was lost after repeated subcultures at 37 degrees C, which selected for bacterial populations having lower in vivo survival. Subculturing Y. enterocolitica O3 from 37 to 25 degrees C restored the cross-immunogenicity although the in vivo survival remained low.

The successful isolation of Yersinia pseudotuberculosis from the stool of an asymptomatic family member of a patient with yersinia septicemia is presented. Cold enrichment permitted the isolation after 4 weeks of refrigerator incubatio,.

Endogenous interleukin-12 (IL-12) mediates protection against Yersinia enterocolitica in C57BL/6 mice by triggering gamma interferon (IFN-gamma) production in NK and CD4+ T cells. Administration of exogenous IL-12 confers protection against yersiniae in Yersinia-susceptible BALB/c mice but exacerbates yersiniosis in resistant C57BL/6 mice. Therefore, we wanted to dissect the different mechanism...

Colicin FY is a plasmid encoded toxin that recognizes a yersinia-specific outer membrane protein (YiuR) as a receptor molecule. We have previously shown that the activity spectrum of colicin FY comprises strains of the genus Yersinia. In this study, we analyzed the activity of colicin FY against 110 Yersinia enterocolitica isolates differing in geographical origin and source. All isolates were ...

We report the complete solid-state MAS NMR resonance assignment of a medium-sized, trimeric membrane protein, YadA-M. The protein YadA (Yersinia adhesin A) is an important virulence factor of enteropathogenic Yersinia species (such as Yersinia enterocolitica and Yersinia pseudotuberculosis). YadA is localized on the bacterial cell surface and is involved in adhesion to host cells and tissues. I...

Yersinia are Gram-negative, rod-shaped facultative anaerobes, and some of them, Yersinia enterocolitica, Yersinia pseudotuberculosis, and Yersinia pestis, are pathogenic in humans. Rapid and accurate identification of Yersinia strains is essential for appropriate therapeutic management and timely intervention for infection control. In the past decade matrix-assisted laser desorption ionization ...
