Yersinia, (genus Yersinia ), any of a group of ovoid- or rod-shaped bacteria of the family Enterobacteriaceae. Yersinia are gram-negative bacteria and are described as facultative anaerobes, which means that they are capable of surviving in both aerobic and anaerobic environments Yersinia pestis (formerly Pasteurella pestis) is a gram-negative, non-motile, rod-shaped, coccobacillus bacterium, without spores. It is a facultative anaerobic organism that can infect humans via the Oriental rat flea (Xenopsylla cheopis). It causes the disease plague, which takes three main forms: pneumonic, septicemic, and bubonic.There may be evidence suggesting Y. pestis originated in.

Formerly classified as Pasteurella , Yersinia have been reclassified as Enterobacteriaceae and the genus renamed. Louis Pasteur, although nominal head of the Institute, was not entitled to the credit or the discovery of the plague bacillus Tento bakteriální druh patří do čeledi G− tyčinek Enterobacteriaceae.Donedávna byly sérotypy salmonel považovány za různé samostatné druhy. Genetickou analýzou bylo zjištěno, že se jedná o jeden druh označený jako Salmonella enterica rozdělený na sedm poddruhů. Pro člověka jsou patogenní druhy zařazené do subspecies enterica
Yersinia is a genus of gram-negative, rod-shaped bacteria from the Enterobacteriacae family that cause yersiniosis. These pathogens are the third most common cause of bacterial intestinal diseases in Germany after salmonella and campylobacter. Of 18 known species, Yersinia (Y.) enterocolitica and Y. pseudotuberculosis caus Y. enterocolitica are gram-negative, rod-shaped bacteria that give rise to food poisoning. Other species in this family include Y. pseudotuberculosis and Y. pestis, The unique features that distinguish the Y. enterocolitica genome from all other Yersinia species are the coenzyme B12 biosynthetic (cbi) and 1,2-propanediol-degradation (pdu.

It causes the deadly disease called bubonic plague, or simply the plague Yersinia pestis infection. edited August 2015. The Yersinia pestis infection guidelines were first published in the J Feline Med Surg 2013; 15: 582-584 by Maria Grazia Pennisi.. Agent properties . Yersinia pestis is a gram-negative nonmotile, rod-shaped, facultative anaerobe with bipolar staining (giving it a safety pin appearance; Fig. 1) that belongs to the family Enterobacteriaceae Here, we showed that the Yersinia inner rod protein YscI directly interacts with the needle protein YscF inside the bacterial cells and that this interaction depends on amino acid residues 83-102 in the carboxyl terminus of YscI. Alanine substitution of Trp-85 or Ser-86 abrogated the binding of YscI to YscF as well as needle assembly and the. Yersinia pestis may be identified microscopically by examination of Gram, Wright, Giemsa, or Wayson's stained smears of peripheral blood, sputum, or lymph node specimen.Visualization of bipolar-staining, ovoid, Gram-negative organisms with a safety pin appearance permits a rapid presumptive diagnosis of plague
