    Abstract. Bacteria of the genus Yersinia have been recognized for centuries as the cause of devastating human illness in the form of plague caused by Yersinia pestis and epizootic disease in animals and mesenteric lymphadenitis in humans due to Yersinia pseudotuberculosis. In more recent years, a third member of the genus, Yersinia enterocolitica, has been reported with increasing frequency Cited by: 3. Transfusion Reactions: Case Studies. 1.

    Yersinia invasion studies of HeLa cell monolayers (gentamicin protection assay) About × 10 5 HeLa cells were seeded in each well of a 24‐well plate (Nunc). Twenty‐four hours later the confluent monolayers were either infected with yersiniae (moi = 10) or pre‐incubated with inhibitors (described below) and subsequently infected with Cited by: The prevalence of Yersinia enterocolitica in humans, monitored from to by bacteriological examination of patients with diarrhoea, was compared with seroprevalence data from finisher pigs and bacteriological results from meat samples. The number of patients diagnosed with Y enterocolitica infection declined consistently from cases in to cases in Author: Jaap Boes, Bent Nielsen, Peter Gerner-Smidt.

Although Yersinia enterocolitica genomes are highly heterogeneous, they contain a conserved N-acylhomoserine lactone-dependent (AHL) quorum sensing (QS) system consisting of the luxR and luxI orthologs yenR and yenI respectively. Certain hypervirulent strains also contain a putative orphan luxR gene, ycoR, that is not linked to an AHL by: 2.

Consumption of pork has been associated with Y. enterocolitica infections in epidemiological by: 4. Yersinia is a genus of bacteria in the family Yersiniaceae.

Yersinia species are Gram-negative, coccobacilli bacteria, a few micrometers long and fractions of a micrometer in diameter, and are facultative anaerobes. Some members of Yersinia are pathogenic in humans; in particular, Y.

pestis is the causative agent of the plague. Rodents are the natural reservoirs of Yersinia; less frequently Class: Gammaproteobacteria. Yersinia enterocolitica is an invasive enteric pathogen whose virulence determinants have been the subject of intensive investigation, but not all strains of Y.

enterocolitica are equally virulent. Schemes for subtyping Yersinia species include bacteriophage typing, multienzyme electrophoresis, multilocus sequence typing, and the demonstration of restriction fragment length polymorphisms of.

Both Yersinia enterocolitica and Yersinia pseudotuberculosis can cause similar histologic features. 77 Marked lymphoid hyperplasia and superficial ulceration are typical. Some cases exhibit scattered epithelioid granulomas that develop central necrosis and neutrophil infiltration (Fig.

).These granulomas are often observed in germinal centers, and occasional multinucleated cells. Yersinia enterocolitica, an enteropathogenic species belonging to the genus Yersinia, is widely distributed in nature and affects both humans and animals.

In the past 10 years, this microorganism has been extensively studied in numerous publications, focusing on molecular biology, basic genetics, virulence, epidemiology and genomics.

There are a number of studies that support the connection between Yersinia enterocolitica and Hashimoto’s disease including this one. I get great results with Hashimoto’s disease when we find this infection and eradicate it from the body.

Yersinia enterocolitica are ubiquitous, being isolated frequently from soil, water, animals, and a variety of foods. They comprise a biochemically heterogeneous group that can survive and grow at refrigeration temperatures.

The ability to propagate at refrigeration temperatures is of considerable significance in food hygiene. Virulent strains of Yersinia invade mammalian cells such as Cited by: Yersinia enterocolitica are ubiquitous, being isolated frequently from soil, water, animals, and a variety of foods.

Yersinia pseudotuberculosis is a Gram-negative bacterium that causes Far East scarlet-like fever in humans, who occasionally get infected zoonotically, most often through the food-borne route.

Animals are also infected by Y. bacterium is urease lty: Infectious disease. The etiologic agent in this case is Yersinia enterocolitica. Disease caused by this organism frequently mimics the symptoms of appendicitis, although it has been implicated in a variety of clinical illnesses such as bacteremia, cholecystitis, and mesenteric lymphadenitis.

Yersinia enterocolitica is reported to cause diarrhoeal disease in humans at least fold more often than Y. pseudotuberculosis and will be the organism primarily dealt with in this chapter.

enterocolitica is typically associated with terminal ileitis and Y. pseudotuberculosis with mesenteric adenitis. However, both organisms may cause. In this book leading Yersinia researchers review the hot topics in the systems biology and control of these important bacteria. Topics include: transcriptome analysis of the bacterial response to the host and of the host response to a Yersinia infection; proteome analysis of the bacterial and host responses; treatment and antibiotic resistance; vaccines; surveillance and control.

A 3½-year-old girl presented with persistent abdominal pain, fever, vomiting, and diarrhea accompanied by rash, oral ulceration, anemia, and an elevated sedimentation rate.

Yersinia enterocolitica: Yersinia enterocolitica includes well-established pathogens and environmental strains that are ubiquitous in terrestrial and fresh water ecosystems.

Evidence from large outbreaks of yersiniosis and from epidemiological studies of sporadic cases has shown that Yersinia enterocolitica is a foodborne pathogen, and that in.Yersinia enterocolitica. General characteristics.

Y. enterocolitica, a small rod-shaped, Gram-negative bacterium, is often isolated from clinical specimens such as wounds, faeces, sputum and mesenteric lymph nodes.
