Current genetic manipulation techniques include insertion of DNA by random transposon mutagenesis and homologous recombination via suicide vectors. This study describes the construction of a shuttle vector, pMaORI, that replicates within saprophytic, intermediate, and pathogenic leptospires. The shuttle vector was constructed by the insertion of a 2.9-kb DNA segment including the\n            <jats:italic>parA<\/jats:italic>\n            ,\n            <jats:italic>parB<\/jats:italic>\n            , and\n            <jats:italic>rep<\/jats:italic>\n            genes into pMAT, a plasmid that cannot replicate in\n            <jats:named-content content-type=\"genus-species\">Leptospira<\/jats:named-content>\n            spp. and contains a backbone consisting of an\n            <jats:italic>aadA<\/jats:italic>\n            cassette,\n            <jats:italic>ori<\/jats:italic>\n            R6K, and\n            <jats:italic>oriT<\/jats:italic>\n            RK2\/RP4. The inserted DNA segment was isolated from a 52-kb region within\n            <jats:named-content content-type=\"genus-species\">Leptospira<\/jats:named-content>\n            <jats:italic>mayottensis<\/jats:italic>\n            strain 200901116 that is not found in the closely related strain\n            <jats:named-content content-type=\"genus-species\">L. mayottensis<\/jats:named-content>\n            200901122. Because of the size of this region and the presence of bacteriophage-like proteins, it is possible that this region is a result of a phage-related genomic island. The stability of the pMaORI plasmid within pathogenic strains was tested by passaging cultures 10 times without selection and confirming the presence of pMaORI. Concordantly, we report the use of\n            <jats:italic>trans<\/jats:italic>\n            complementation in the pathogen\n            <jats:named-content content-type=\"genus-species\">Leptospira interrogans<\/jats:named-content>\n            . Transformation of a pMaORI vector carrying a functional copy of the\n            <jats:italic>perR<\/jats:italic>\n            gene in a null mutant background restores the expression of PerR and susceptibility to hydrogen peroxide comparable to that of wild-type cells. In conclusion, we demonstrate the replication of a stable plasmid vector in a large panel of\n            <jats:named-content content-type=\"genus-species\">Leptospira<\/jats:named-content>\n            strains, including pathogens. The shuttle vector described will expand our ability to perform genetic manipulation of\n            <jats:named-content content-type=\"genus-species\">Leptospira<\/jats:named-content>\n            spp.\n          <\/jats:p>","DOI":"10.1128\/aem.00173-15","type":"journal-article","created":{"date-parts":[[2015,2,28]],"date-time":"2015-02-28T04:09:48Z","timestamp":1425096588000},"page":"3176-3181","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":54,"title":["A Replicative Plasmid Vector Allows Efficient Complementation of Pathogenic Leptospira Strains"],"prefix":"10.1128","volume":"81","author":[{"given":"Christopher J.","family":"Pappas","sequence":"first","affiliation":[{"name":"Institut Pasteur, Unit\u00e9 Biologie des Spiroch\u00e8tes, Paris, France"},{"name":"Manhattanville College, Department of Biology, Purchase, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadia","family":"Benaroudj","sequence":"additional","affiliation":[{"name":"Institut Pasteur, Unit\u00e9 Biologie des Spiroch\u00e8tes, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathieu","family":"Picardeau","sequence":"additional","affiliation":[{"name":"Institut Pasteur, Unit\u00e9 Biologie des Spiroch\u00e8tes, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/nrmicro2208"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-662-45059-8_4"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1128\/JB.182.20.5700-5705.2000"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.02172-07"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1099\/mic.0.26065-0"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.00775-10"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0001607"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.01067-06"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1099\/ijs.0.066597-0"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.00435-10"},{"key":"e_1_3_2_12_2","first-page":"45","article-title":"Nutrition of Leptospira pomona and growth of 13 other serotypes: fractionation of oleic albumin complex and a medium of bovine albumin and polysorbate 80","volume":"26","author":"Ellinghausen HC","year":"1965","unstructured":"Ellinghausen HC, McCullough WG. 1965.
