Were determined the sensitivity profile and resistance phenotypes of Escherichia coli associated with urinary infections in patients treated at Belén de Trujillo Hospital from January to September, 2018. Different urine samples were processed during that period; E.coli culture colonies were inoculated into MicroScan ® panels for identification and automated sensitivity study. The following classification was used to establish the resistance phenotype associated with beta-lactams; enicillin-producing strains: resistance to ampicillin and preserved sensitivity to amoxicillin-clavulanic acid and the rest of the cephalosporins studied; Penicillinase hyperproducers: ampicillin resistance, decreased resistance or sensitivity to amoxicillin-clavulanic acid and decreased sensitivity or resistance to cefuroxime; Amp C: resistance to ampicillin, amoxicillin-clavulanic acid, cefoxitin and the res...
