|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 families introduced within the order Enterobacterales|
The order Enterobacterales (formerly called Enterobacteriales) previously consisted of bacteria with different properties and phylogenetically, these bacteria were far apart. In order for the taxonomy to be more in line with phylogeny, some of these bacteria have, therefore, been sorted into 6 new families.Published 2022-04-13. Read more...
