Antimicrobial resistance and plasmid profiles of urinary Escherichia coli isolates from Jordanian patients.
We investigated antimicrobial resistance patterns and plasmid profiles of uropathogenic Escherichia coli isolates from inpatients and outpatients at Jordan University Hospital in 2000 and 2001. E. coli accounted for 32.4% and 37.4% of all isolates respectively. The lowest susceptibility was for ampicillin (11%), cotrimoxazole (23%) and tetracycline (26%). The relative incidence of resistant isolates of E. coli to nalidixic acid, gentamicin, norfloxacin, cefuroxime and nitrofurantoin was significantly greater for inpatients than for outpatients (P< 0.05). A large, transferable R-plasmid of 28 kb was found in most E. coli isolates (67%) that were resistant to at least ampicillin, cotrimoxazole and tetracycline. This R-plasmid reservoir may contribute to the spread of multiple antibiotic resistance in our Region.
