However, there is a lack of information on circulating\n            <jats:named-content content-type=\"genus-species\">Leptospira<\/jats:named-content>\n            strains in remote parts of the world. We describe the serological and molecular features of leptospires isolated from 94 leptospirosis patients in Mayotte, a French department located in the Comoros archipelago, between 2007 and 2010. Multilocus sequence typing identified these isolates as\n            <jats:named-content content-type=\"genus-species\">Leptospira interrogans<\/jats:named-content>\n            ,\n            <jats:named-content content-type=\"genus-species\">L. kirschneri<\/jats:named-content>\n            ,\n            <jats:named-content content-type=\"genus-species\">L. borgpetersenii<\/jats:named-content>\n            , and members of a previously undefined phylogenetic group. This group, consisting of 15 strains, could represent a novel species. Serological typing revealed that 70% of the isolates belonged to the serogroup complex Mini\/Sejroe\/Hebdomadis, followed by the serogroups Pyrogenes, Grippotyphosa, and Pomona. However, unambiguous typing at the serovar level was not possible for most of the strains because the isolate could belong to more than one serovar or because serovar and species did not match the original classification. Our results indicate that the serovar and genotype distribution in Mayotte differs from what is observed in other regions, thus suggesting a high degree of diversity of circulating isolates worldwide. These results are essential for the improvement of current diagnostic tools and provide a starting point for a better understanding of the epidemiology of leptospirosis in this area of endemicity.\n          <\/jats:p>","DOI":"10.1128\/jcm.05931-11","type":"journal-article","created":{"date-parts":[[2011,12,8]],"date-time":"2011-12-08T06:03:05Z","timestamp":1323324185000},"page":"307-311","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":53,"title":["Human Leptospira Isolates Circulating in Mayotte (Indian Ocean) Have Unique Serological and Molecular Features"],"prefix":"10.1128","volume":"50","author":[{"given":"P.","family":"Bourhy","sequence":"first","affiliation":[{"name":"Institut Pasteur, Unit\u00e9 de Biologie des Spiroch\u00e8tes, National Reference Centre for Leptospirosis, WHO Collaborating Center for the Epidemiology of Leptospirosis, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Collet","sequence":"additional","affiliation":[{"name":"Hospital Centre of Mayotte (CHM), Mayotte, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Lernout","sequence":"additional","affiliation":[{"name":"Regional Office (Cire) of the French Institute for Public Health Surveillance (Institut de Veille Sanitaire), Mayotte, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Zinini","sequence":"additional","affiliation":[{"name":"Institut Pasteur, Unit\u00e9 de Biologie des Spiroch\u00e8tes, National Reference Centre for Leptospirosis, WHO Collaborating Center for the Epidemiology of Leptospirosis, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
