Species/Subspecies: Leptospira borgpetersenii
Categories: Zoonotic; motile; notifiable diseases and bacteria
Etymology: Genus name: thin helix (coil).
Species epithet: named after the Danish microbiologist C. Borg-Petersen.
Significance:Leptospirosis is said to be the most wide spread zoonotic infection in Nature.
  [Important]

Gram +/Gram -:G-
Metabolism: Aerobic

Fermentation of carbohydrates: Does not ferment karbohydrates.
Spec. Char.: Generation time: 6-8 h.
Disease:Leptospirosis, which is a zoonosis.
Hosts: Humans etc.
Clinical Picture:
Genome Sequence:
Acc-noStrainSize (bp)Genome
NC_008510 and NC_008511 JB197 3 876 235 2c + 0 
Chrom. I (3 576 473 bp) and chrom. II (299 762 bp), respectively.

16S rRNA Seq.:
Acc-noStrainNumber of NTOperon
AM050569 VLA Weybridge 1318 
Two rRNA genes on chrom. I and none on chrom. II.

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.
Reference(s): No. 109
