|Categories:||Zoonotic; motile; notifiable diseases and bacteria|
|Etymology:||Genus name: thin helix (coil). |
Species epithet: named after L. Kirschner,
|Significance:||Leptospirosis is said to be the most wide spread zoonotic infection in Nature.
|Type Strain:||Serovar Cynopteri, strain 3522C = ATCC 49945.|
|Micromorphology:||"Sewing thread thin" (0.1 x 6-12 µm), helical and with a hook on each end. Motile and has two periplasmatic flagella.|
|Gram +/Gram -:||G-|
|Fermentation of carbohydrates:||Does not ferment karbohydrates.|
|Spec. Char.:||Generation time: 6-8 h.|
|Disease:||Leptospirosis, which is a zoonosis.
|16S rRNA Seq.:|
||About 25 different species have been described within the genus Leptispira. L. kirschneri is closely related to L. interrogans. See the phylogenetic tree (Fig. 115:1).|
|Legislation:||Leptospirosis is notifyable in Sweden.|
|Comment:||There are different serovars and from a clinical point of view, the serovar is more important than the species as pathogenicity is associated with serovar, rather than species and different species may belong to the same serovar.|

|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...
