Deoxyribonucleic acid hybridization (hydroxyapatite method, 55 and 70°C) was used to characterize 38 serovars from 22 named serogroups of Leptospira interrogans and Leptospira biflexa, 6 serovars from 4 new unnamed serogroups of Leptospira interrogans, and single serovars of the proposed species Leptospira parva and Leptonema illini. Deoxyribonucleic acid relatedness confirmed the validity of Leptospira parva and Leptonema illini. The well-accepted species Leptospira interrogans and Leptospira biflexa, as currently defined, were extremely heterogeneous. Relatedness results revealed at least five new species among the parasitic serovars formerly included in Leptospira interrogans and two new species among the saprophytic serovars formerly included in Leptospira biflexa. Serogrouping did not equate with species identification, as serovars from several different subserogroups belonged to different species. The new species named in this paper are Leptospira, noguchii, Leptospira weilii, Leptospira santarosai, Leptospira borgpetersenii, Leptospira meyeri, Leptospira wolbachii, and Leptospira inadai.
