|Etymology:||Genus name: named after the French bacteriologist A.J.E. Yersin, who in 1894 first isoleted the bacterium which causes the plague.|
Species epithet: from false tuberculosis.
|Type Strain:||ATCC 29833 = CCUG 5855 = NCTC 10275|
|Micromorphology:||Motile rods with peritrichous flagella|
|Gram +/Gram -:||G-|
|Other Enzymes:||Tryptophanase - and urease +|
|Fermentation of carbohydrates:||Glucose(gas) -, Mannitol +, Rhamnose +, Sorbitol + and Sucrose -. Cf. other Yersinia spp.|
Man: Food poisoning
|Hosts:||Rodents, deer, cattle, sheep, goat, pig, cage birds, man|
|Clinical Picture:||Animals: Tuberculosis-like symptoms. Localized tissue necrosis and granulomas in the spleen, liver, and lymph node.
Man: Abdominal pain and fever.
|Virulence Factors:||The virulence plasmid common to pathogenic Yersinia species encodes a number of secreted proteins denoted Yops (Yersinia outer proteins). A novel plasmid-encoded virulence determinant of Yersinia pseudotuberculosis, YopK has recently been identified.|
|16S rRNA Seq.:|
||Within the genus Yersinia, 20 species have been described. All species belong to the family Enterobacteriaceae.|
|The revised taxonomy of the mollicutes|
The revised taxonomy of mollicutes (mycoplasmas) has now been introduced on VetBact, which means that many of the species have been given new genus names or moved to another higher taxon.Published 2021-11-25. Read more...
