Natural genetic transformation of clinical isolates of Escherichia coli in urine and water.
نویسندگان
چکیده
Transfer of plasmid-borne antibiotic resistance genes in Escherichia coli wild-type strains is possible by transformation under naturally occurring conditions in oligotrophic, aquatic environments containing physiologic concentrations of calcium. In contrast, transformation is suppressed in nitrogen-rich body fluids like urine, a common habitat of uropathogenic strains. Current knowledge indicates that transformation of these E. coli wild-type strains is of no relevance for the acquisition of resistance in this clinically important environment.

Background & Aim: Important challenge for treatment of urinary tract infections is the spread of extended-spectrum beta-lactamases (ESBLs) producing Escherichia coli. Therefore, the frequencies of main beta-lactamase genes, resistance to beta-lactams and the ability of ESBLs production in urinary and fecal Escherichia coli of women with urinary tract infections were compared. Methods: In 60 Es...
