[Antimicrobial susceptibility of Escherichia coli isolated from bacteriurias in Bierzo health area during 2003].
OBJECTIVE
Sensitivity to antibiotics of Escherichia coli isolated from intrahospital and extrahospital bacteriurias is analyzed.


METHODS
Sensitivity to nineteen antibiotics used in the clinical practice was determined in strains of Escherichia coli isolated from intrahospital and extrahospital bacteriurias.


RESULTS
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).


CONCLUSIONS
The knowledge of the sensitivity of uropathogens to antimicrobians can allow us to initiate empirical therapy of urinary tract infections.
