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

New names of bacterial phyla![]() The taxonomic category phylum was previously not regulated by the International Code of Nomenclature of Prokaryotes (ICNP), but now this has changed and it was decided to revise the names of bacterial phyla. All phyla must be written in italics (which has been done on VetBact also before) and have the ending -ota. Published 2023-03-01. Read more... |
The taxonomy of chlamydias Species within the family Chlamydiaceae were previously divided into two genera Chlamydia and Chlamydophila. However, the differences between these two genera were not that great and many research groups have not accepted this division. Therefore, the genus Chlamydophila has been returned to the genus Chlamydia and this change has now been incorporated in VetBact Published 2023-03-15. Read more... |
