Abstract

Two spirochetes (designated strains LGVF01 and LGVF02T) were isolated from soil samples in San Juan, Puerto Rico in HAN media after selection using a combination of ELISA, agar plating, and colony screening by Fluorescent Antibody Testing (FAT) and PCR for lipL32 and secY. Isolates were helix-shaped, aerobic, fast-growing, and highly motile. Genome sequence analysis indicated that both strains should be classified as members of a novel species within the pathogenic (P1) clade of the genus Leptospira. The average nucleotide identity between the two strains was 99.2%, but below 93.2% when compared to any previously described leptospiral species. Serotyping of strain LGVF02T indicates that it does not belong within any sero-group of Leptospira suggesting it also represents a new serovar. Collectively, strains LGVF01 and LGVF02T represent a new species of pathogenic leptospires for which the name Leptospira sanjuanensis sp. nov. is proposed. The type strain is LGVF02T (=NVSL-LGVF02T=KIT0302T).
