Leptospira mayottensis
Leptospira mayottensis is a pathogenic species of Leptospira in the family Leptospiracea. As causative agents of Leptospirosis they primarily infect humans, livestock, dogs, and small mammals. They are endemic to the island of Mayotte located in the Indian ocean, as well as being found in Madagascar. L. mayottensis is closely related to Leptospira borgpetersenii.
L. mayottensis was first isolated from patient samples in Mayotte. Originally L. mayottensis was identified as an L. borgpetersenii-like phylogenetic group. However based upon rRNA 16s sequencing they were determined to be their own species. In addition to being isolated from humans, L. mayottensis has also been isolated from the small mammals Microgale cowani, ''Rattus rattus, and Tenrec ecaudatus. The level of diversity from isolates derived from Madagascar compared to Mayotte may indicate L. mayottensis'' originated from Madagascar.
