Yersinia proxima is a Gram-negative bacterium in the family Yersiniaceae that is phylogenetically close to Yersinia enterocolitica. [1] Members of this species has been found in human feces.
Yersinia pestis is a gram-negative, non-motile, coccobacillus bacterium without spores that is related to both Yersinia enterocolitica and Yersinia pseudotuberculosis, the pathogen from which Y. pestis evolved and responsible for the Far East scarlet-like fever. It is a facultative anaerobic organism that can infect humans via the Oriental rat flea. It causes the disease plague, which caused the Plague of Justinian and the Black Death, the deadliest pandemic in recorded history. Plague takes three main forms: pneumonic, septicemic, and bubonic. Yersinia pestis is a parasite of its host, the rat flea, which is also a parasite of rats, hence Y. pestis is a hyperparasite.
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, other mammals serve as the host. Infection may occur either through blood or in an alimentary fashion, occasionally via consumption of food products contaminated with infected urine or feces.
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. pseudotuberculosis. The bacterium is urease positive.
Yersinia ruckeri is a species of Gram-negative bacteria, known for causing enteric redmouth disease in some species of fish. Strain 2396-61 is its type strain.
Pasteurella lymphangitidis is a bacterium; it causes bovine lymphangitis. Its reclassification to Yersinia has been proposed, given it poses a 99% sequence similarity to both Yersinia pseudotuberculosis and Yersinia pestis.
Yersinia mollaretii is a Gram-negative species of bacteria. The species is named after Henri Mollaret, the former head of the National Yersinia Center at Institut Pasteur.
Yersinia bercovieri is a Gram-negative species of enteric bacteria.
Psychrobacter is a genus of Gram-negative, osmotolerant, oxidase-positive, psychrophilic or psychrotolerant, aerobic bacteria which belong to the family Moraxellaceae and the class Gammaproteobacteria. The shape is typically cocci or coccobacilli. Some of those bacteria were isolated from humans and can cause humans infections such as endocarditis and peritonitis. This genus of bacteria is able to grow at temperatures between −10 and 42 °C. Rudi Rossau found through DNA-rRNA hybridization analysis that Psychrobacter belongs to the Moraxellaceae. The first species was described by Juni and Heym. Psychrobacter occur in wide range of moist, cold saline habitats, but they also occur in warm and slightly saline habitats.
Yersinia hibernica is a species of Yersinia that was originally isolated in a pig-production environment. The type strain is CFS1934. This species has previously been misidentified as Yersinia enterocolitica and Yersinia kristensenii but it may be distinguished biochemically by lack of sucrose utilization. In addition to pig related environments, Y. hibernica has also been isolated from the feces of Rattus norvegicus and Hydrochoerus hydrochaeris.
Yersinia aleksiciae is a Gram-negative bacteria that is commonly isolated from the feces of warm-blooded animals such as humans, reindeers, and pigs. The type strain is Y159.
Yersinia nurmii is a Gram-negative species of Yersinia that was originally isolated in packaged broiler meat cuts. The type strain is APN3a-c.
Yersinia pekkanenii is a Gram-negative species of Yersinia that has been isolated from water, soil, and lettuce samples. The type strain is ÅYV7.1KOH2.
Yersinia rohdei is a Gram-negative species of Yersinia that was originally isolated from the feces of humans and dogs in addition to water surfaces. The type strain is ATCC 43380. Y. rohdei strains have also been isolated from reindeer and kelp gull from the sub-Antarctica South Georgia island.
Yersinia similis is a Gram-negative bacteria species of Yersinia that resembles Yersinia pseudotuberculosis phenotypically but differs on the basis of 16S ribosomal RNA sequences. The type strain Y228 was originally isolated from a rabbit in Germany.
Yersinia thracica is a Gram-negative species of enteric bacteria in the Yersinia genus that is closely related to Yersinia kristensenii. Reportedly, it has only been isolated in animals. The type strain, IP34646T, was isolated from diseased rainbow trout while other isolates are from birds, pig feces, and wild boars.
Yersinia vastinensis is a Gram-negative species of bacteria that has been isolated from human stools. All reported strains were isolated in France.
Yersinia rochesterensis is a Gram-negative, motile, rod-shaped bacterium that forms circular colonies and was isolated from human feces. This potentially pathogenic species has been isolated in human stools in France and in the United States where it was characterized at the Mayo Clinic. A Y. rochesterensis strain, isolated from hare and initially identified as Yersinia kristensenii, was serotyped as O:12,25.
Yersinia alsatica is a Gram-negative bacterium in the family Yersiniaceae that has been isolated from human stool.
Yersinia artesiana are short Gram-negative rod bacteria in the Yersiniaceae family that have been isolated from human stool.
Yersinia canariae is a Gram-negative species of Yersinia that was isolated from a human displaying symptoms of yersiniosis. Biochemically, it is similar to Yersinia enterocolitica but whole-genome sequencing data determined it is a distinct species.
