|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.|
|The revised taxonomy of the mollicutes (mycoplasmas)|
About 2 years ago, the taxonomy of mycoplasmas was revised at VetBact, because a research group had proposed that 5 new genera should be included together with the genus Mycoplasma. This also had consequences for higher taxa within the phylum, which was then called Tenericutes. Now another group of researchers has suggested that the new names should be rejected.Published 2023-10-03. Read more...
