Taxonomy/phylogeny:
Leptospira borgpetersenii  
About 25 different species have been described within the genus Leptispira. L. borgpetersenii is closely related to L. santarosai and L. weilii. See the phylogenetic tree (Fig. 116:3).
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.
