Caracterización fenotípica de grupo filogenético y genes de resistencia en Escherichia coli BLEE positivo, aisladas de muestras provenientes de mujeres adultas con infección del tracto urinario del hospital Manuel Ygnacio Monteros (IESS) durante el período marzo – agosto 2017.

Abstract

The urinary tract infections are the most recurrent at the community and intrahospital level, which predominate in female people, due to the anatomical condition; determinated by the bacteria colonization principally extra-intestinal pathogenic Escherichia coli (ExPEC), the same ones that have features of virulence that allow them to invade and promote diseases in bodily sites outside their habitat; however, several strains have developed multiresistance to medications especially betalactámicos, which have been associated with the formation of beta lactamases. For that reason, the objective of this research work was to determinate the phylogenetic group, resistance genes and evaluate the relationship between these two isolated groups of samples from women in the “Manuel Ygnacio Monteros” hospital. It was identify three phylogenetic groups A, B2 y D con 10%, 31% y 59% respectively, while the main resistance genes characterized were the 95% bla CTX-M, 48% bla CTX-M13. Although no significant values were found between the phylogenetic group, resistance genes and health service, the prevalence of phylogenetic group D and the resistance gene CTX-M at the community level was observed.
