Abstract

Three strains, CLM-U50, CLM-R50 and IVIC-Bov1, belonging to the genus , were isolated in Venezuela from a patient with leptospirosis, a domestic rat () and a cow (), respectively. The initial characterisation of these strains based on the gene (16S rRNA) suggested their designation as a novel species within the ‘intermediates’ group of the genus . Further phylogenomic characterisation based on single copy core genes was consistent with their separation into a novel species. The average nucleotide identity between these three strains was >99 %, but below 89 % with respect to any previously described leptospiral species, also supporting their designation as a novel species. Given this evidence, these three isolates were considered to represent a novel species, for which the name sp. nov. is proposed, with CLM-U50 (=CIP 111407=DSM 105752) as the type strain.
