Salvador, Bahia, BrasilA major limitation in the clinical management and experimental research of leptospirosis is the poor performance of the available methods for the direct detection of leptospires. In this study, we compared real-time PCR (qPCR), targeting the lipL32 gene, with the immunofluorescent imprint method (IM) for the detection and quantification of leptospires in kidney samples from the rat and hamster experimental models of leptospirosis. Using a virulent strain of Leptospira interrogans serovar Copenhageni, a chronic infection was established in the rat model, which were euthanized 28 days post-infection, while the hamster model simulated an acute infection and the hamsters were euthanized eight days after inoculation. Leptospires in the kidney samples were detected using culture isolation, qPCR and the IM, and quantified using qPCR and the IM. In both the acute and chronic infection models, the correlation between quantification by qPCR and the IM was found to be positive and statistically significant (P<0.05). Therefore, this study demonstrates that the IM is a viable alternative for not only the detection but also the quantification of leptospires, particularly when the use of qPCR is not feasible.Rim/metabolismoLeptospira interrogans/metabolismoLeptospirose/microbiologiaMicroscopia de Fluorescência/métodosReação em Cadeia da Polimerase em Tempo Real/métodosAnimaisCricetinaeFemininoInfecçãoLeptospirose/patologiaMesocricetusRatosRatos WistarAnálise de Sequência de DNAinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da FIOCRUZ (ARCA)instname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZORIGINALChagas Junior AD Detection and quantification....pdfChagas Junior AD Detection and quantification....pdfapplication/pdf178080https://www.arca.fiocruz.br/bitstream/icict/5846/1/Chagas%20Junior%20AD%20Detection%20and%20quantification....pdfb2561b9825462940327c01c8b52fc3cdMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-82008https://www.arca.fiocruz.br/bitstream/icict/5846/2/license.txt06db3f0df647fd9ddff657403bbe0ee2MD52TEXTChagas Junior AD Detection and quantification....pdf.txtChagas Junior AD Detection and quantification....pdf.txtExtracted texttext/plain24913https://www.arca.fiocruz.br/bitstream/icict/5846/5/Chagas%20Junior%20AD%20Detection%20and%20quantification....pdf.txt6bedbc94a4f9b7ea9e5ddb72cfeb2a56MD55THUMBNAILChagas Junior AD Detection and quantification....pdf.jpgChagas Junior AD Detection and quantification....pdf.jpgGenerated Thumbnailimage/jpeg2461https://www.arca.fiocruz.br/bitstream/icict/5846/4/Chagas%20Junior%20AD%20Detection%20and%20quantification....pdf.jpga386aeea0581c0a61051f12b4ccb01a9MD54icict/58462023-03-15 14:33:01.267oai:www.arca.fiocruz.br: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Repositório InstitucionalPUBhttps://www.arca.fiocruz.br/oai/requestrepositorio.arca@fiocruz.bropendoar:21352023-03-15T17:33:01Repositório Institucional da FIOCRUZ (ARCA) - Fundação Oswaldo Cruz (FIOCRUZ)false
