Phenotypic analysis of antibiotic resistant E. coli recovered from urban aquatic environment in Banda Aceh, Indonesia

Abstract

Of aquatic environment, antibiotic resistant bacteria, including total coliforms and E. coli disseminate and emerge at an alarming rate. The study aims to determine enumerate, isolate,E. coliand determine their antibiotic resistance and compare between those which were recovered from residentials and home industries in Banda Aceh and its surrounding area. The bacterial density and antibiotic susceptibility of total coliforms and E. coli were determined using Standard Total Coliform Multiple-Tube (MPN) Fermentation method and the disk diffusion method, respectively. Despite there was no significant difference of total coliforms and E. coli population between residentials and home industries (P > 0.05) in this study, their density as well as prevalence remained high in the water sample. This might expose serious health risks since the resistance might be easily spread acquired through horizontal gene transfer within the aquatic environment.
