Resumo: | We evaluated the genetic variability of Triatoma brasiliensis, the main vector of Chagas disease in Northeast Brazil, using specimens from three populations. Regions of genomic DNA were amplified by RAPD (Random Amplified Polimorphic DNA), using two primers. The products were visualized after polyacrylamide gel electrophoresis followed by silver staining. A dendrogram constructed through the Dice similarity coefficient allowed for separation of the tested specimens into three distinct groups. The populations captured in areas from Ceará State showed similar profiles, but different from that captured in Piauí State. Our results indicate that RAPD can be used successfully in triatomine studies and suggest the presence of genetic variability between different populations of T. brasiliensis. |

Regiões do DNA genômico foram amplificadas utilizando dois iniciadores randômicos através da técnica de RAPD (Random Amplified Polymorphic DNA), visualizados em géis de poliacrilamida corados pela prata. Os perfis originados se mostraram bastante homogêneos quando comparados intrapopulacionalmente. Populações capturadas em duas regiões diferentes do Estado do Ceará também apresentaram homogeneidade entre si, mas, quando comparadas com a população proveniente do Piauí, foi possível diferenciá-las. Esses resultados, preliminares, indicam que o RAPD pode ser usado com sucesso nos estudos de variabilidade em triatomíneos, bem como sugerem a existência de variabilidade entre diferentes populações de T. brasiliensis pertencentes a uma mesma subespécie.Reports in Public HealthCadernos de Saúde Pública2000-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/1362Reports in Public Health; Vol. 16 No. 6 (2000): Supplement 2Cadernos de Saúde Pública; v. 16 n. 6 (2000): Suplemento 21678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZporhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/1362/2712https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/1362/2713Borges, Érika C.Romanha, Alvaro J.Diotaiuti, Liléiainfo:eu-repo/semantics/openAccess2024-03-06T15:26:23Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/1362Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:01:38.286309Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true |
