Leptospira este un gen de bacterii ce cuprinde un număr relativ mic de specii,^[1] atât patogene cât și saprofite. Prima specie de Leptospira a fost L. interrogans (Spirochaeta interrogans), descrisă în anul 1907, izolată din rinichii bolnavilor de leptospiroză. Genul este divizat în 20 de genomospecii, utilizând hibridizarea ADN:

Specii patogene:

Leptospira interrogans

Leptospira kirschneri

Leptospira noguchii

Leptospira alexanderi

Leptospira weilii

Leptospira genomospecies 1 (alstoni)

Leptospira borgpetersenii

Leptospira kmetyi^[2]

Specii intermediare sau oportuniste:

Leptospira inadai

Leptospira fainei

Leptospira broomii ^[3]

Leptospira licerasiae ^[4]

Leptospira wolffii^[5]

Specii non-patogene:

Leptospira biflexa

Leptospira meyeri

Leptospira wolbachii

Leptospira genomospecies 3 (vanthielii)

Leptospira genomospecies 4 (terpstrae)

Leptospira genomospecies 5 (yanagawae)
