Bacterial Identification and Susceptibility Testing

Sensitivity to antibiotics of Escherichia coli isolated from intrahospital and extrahospital bacteriurias is analyzed.Sensitivity to nineteen antibiotics used in the clinical practice was determined in strains of Escherichia coli isolated from intrahospital and extrahospital bacteriurias.The prevalence of in-vitro susceptibilities to antibiotics were (hospital, state health service clinic, health center-primary-care): imipenem (100%-100%-100%; p=NS), amikacin (100%-100%-99.7%; p=NS), fosfomicyn (98.6%-98.4%-99.6%; p=NS), cefepime (96%-96.9%-98.3%; p=NS), piperacillin-tazobactam (96%-95.3%-96.6%; p=NS), aztreonam (93.5%-94.7%-97.7%; p<0.001), ceftazidime (93.5%-94.3%-97.8%; p<0.001), cefotaxime (93.1%-95%-97.7%; p<0.001), cefixime (92.7%-94.6%-96.7%; p<0.05), nitrofurantoin (92%-94.7%-94.7%; p=NS), cefuroxime (88.4%-93.1%-95%; p<0.001), amoxicillin-clavulanic (87.7%-88.7%-93.8%; p<0.001), tobramicyn (87%-93.7%-93.8%; p<0.001), gentamcin (85.9%-92.8%-93%; p<0.001), cefazolin (84.4%-88.7%-91.6%; p<0.01), ciprofloxacin (63.8%-71.4%-78.4%; p<0.001), norfloxacin (63%-70.8%-78.2%; p<0.001), cotrimoxazole (65.2%-68.6%-74.9%; p<0.01) and ampicillin (35.5%-42.5%-47.8%; p<0.01). (*NS= No significant differences).The knowledge of the sensitivity of uropathogens to antimicrobians can allow us to initiate empirical therapy of urinary tract infections.
