ABSTRACT Background: Escherichia coli (E. coli) are the most common etiological agents of hospital acquired and community acquired urinary tract infections (UTIs) and the incidence of antibiotic resistant strains has been steadily increasing over the past few years resulting in limitation of therapeutic options. Our objectives were to investigate the prevalence and molecular characterization of extended spectrum β- lactamases (ESBLs) ... Read more

In this study antibiotic resistant Escherichia coli from household water collected in Hafr AlBatin, Saudi Arabia, were characterized by prevalence of extended spectrum betalactamase (ESBL). Samples were collected from drinking and washing water at 12 locations. From the 144 samples obtained, Millipore membrane filters incubated on trypton soya agar plates produced colonies that yielded 34 isolates of E. coli as ... Read more
