| Taxonomy/phylogeny:
|
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. | ||||||||
