Levels of quinolones resistance and other antimicrobial in non-pathogenic Escherichia coli strains in children from the periurban area of Lima, Peru

The proportion of resistance found to the evaluated antimicrobials was ampicillin (62.6%),

 cotrimoxazole (48,6%), tetracycline (43,0%) and chloramphenicol (15,8%). We emphasize the high resistance levels  found for quinolones: 32% for nalidixic acid (NAL) and 12% for ciprofloxacin (CIP). These high levels of quinoloneresistance  in non-pathogenic strains isolated from children in this age group highlight the extensive use and the impact of  the intake of this kind of antimicrobials in the community, showing the potential risk of the loss of their utility in the area.
