Evidencia de transferencia horizontal de genes de resistencia a antibióticos provenientes de bacterias ambientales

Abstract

El presente estudio exploró la presencia y la capacidad de diseminación de genes de resis­tencia a antibióticos provenientes de bacterias ambientales. Se recolectó muestras de agua y suelo de zonas prístinas de la Amazonia ecuatoriana (provincias de Sucumbíos, Napo y Orellana) las cuales fueron inoculadas en un medio de grano de trigo modificado (WGM). Algunos de estos cultivos multi-bacterianos (mixtos) demostraron tener bacterias capaces de transferir genes de resistencia a antibióticos a una cepa de Escherichia coli K12. A partir de los cultivos mixtos se aisló 10 cepas bacterianas responsables de esta transferencia. Las cepas aisladas fueron identificadas mediante el secuenciamiento del gen del ARN riboso- mal 16S (16S rDNA) como Serratia sp., Pseudomonas sp., Listonella sp. y Aeromonas sp. El hallazgo más importante del presente trabajo fue el probar que existe transferencia de genes que proveen resistencia a antibióticos como la tetraciclina y ampicilina a partir de bacterias ambientales.
