Pathogenesis Traits and Antimicrobial Resistance Pattern in Escherichia coli Isolates Recovered From Sewage (original) (raw)

ObjectivesEscherichia coli is one of the most potential agents of community and hospital-acquired infections, which can readily acquire non-susceptibility to drugs administered to animals and humans. E. coli, which has been broadly applied as an indicator of fecal contamination in aquatic environments, is routinely conducted non-virulence. Nevertheless, some isolates can be virulence. The main objectives of this work were to survey antibiotic non-susceptibility and to characterize virulence factors and antibiotic resistance genes including traT, fimH, blaCTX, and tetA among the E. coli isolates recovered from sewage in Gonabad, in the northeast of Iran.Materials and MethodsIn this cross-sectional study, a total of 99 non-duplicate strains of E. coli was removed from three types of sewage including poultry (33 isolates), urban (33), and livestock slaughterhouse (33) sewages in Gonabad from May 2016 to April 2017. Then, the antimicrobial susceptibility test and extended-spectrum-beta-...
