|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
|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.|
|New names of taxa within the classification category phylum|
During October 2021, an article was published by A. Oren och G.M. Garrity, in which new names are proposed for a number of taxa within the classification category phylum. This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.Published 2022-09-28.
