objective: since colposcopy biopsy test plays a significant role in the evaluation of cervix, especially in patients with an abnormal result of pap smear test, therefore, this research study was conducted to compare the results of pap smear and colposcopy directed punch biopsy tests at firoozgar and akbarabady hospitals from 2001 to 2003. materials and methods: this cross-sectional study was ca...

The association between positive serology and culture detection of Yersinia spp. in individual pigs was determined. Pieces of diaphragm from 370 pig carcasses were collected for serological analysis, and tonsils and feces of the same carcass were collected for bacteriological analysis. Detection of anti-Yersinia antibodies in meat juice samples was done using an indirect enzyme-linked immunosor...

The consumption of food contaminated with Yersinia can lead to gastrointestinal infections. The cause for this so-called yersiniosis are the species Y. enterocolitica and Y. pseudotuberculosis. Yersinia are rod-shaped bacteria which are very common in our environment. The main reservoir for Yersinia enterocolitica are pigs, meaning that the bacteria can be found in raw pork. For Yersinia pseudo...

Yersinia pseudotuberculosis is a pathogenic enteric bacteria that evades host cellular immune response and resides extracellularly in vivo. Nevertheless, an important contribution of T cells to defense against Yersinia has been previously established. In this study we demonstrate that Lewis rats infected with virulent strains of Y. pseudotuberculosis, mount a Yersinia-specific, RT1-A-restricted...

API 20E strip test, the standard for Enterobacteriaceae identification, is not sufficient to discriminate some Yersinia species for some unstable biochemical reactions and the same biochemical profile presented in some species, e.g. Yersinia ferderiksenii and Yersinia intermedia, which need a variety of molecular biology methods as auxiliaries for identification. The 16S rRNA gene is considered...

BACKGROUND Yersinia species, especially Yersinia enterocolitica, are considered as the most prevalent milk-borne pathogens. Several serological and molecular techniques have been developed for rapid and safe diagnosis of yersiniosis. OBJECTIVES This study was carried out to assess the prevalence rate of Yersinia species, especially Y. enterocolitica, in milk and dairy products in Isfahan prov...

The incidence of human and nonhuman infections of Yersinia pseudotuberculosis in Canada is presented on the basis of a literature review and serotyping of 101 cultures referred to the Canadian National Reference Center for Yersinia enterocolitica and Yersinia pseudotuberculosis.

Infected aneurysms caused by Yersinia are very uncommon and are principally due to Yersinia enterocolitica. We describe the first case of an infected aneurysm caused by Yersinia pseudotuberculosis in an elderly patient with a history of atherosclerotic cardiovascular disease.
