Caracterización y resistencia de escherichia Coli a los antimicrobianos en los hospitales Vicente Corral Moscoso y José Carrasco Arteaga, Cuenca, 2008-2009

Abstract

Objective. To characterize and determine the strength of Escherichia coli in primary cultures in Vicente Corral and Jose Carrasco hospitals of Cuenca city.

Materials and method. A descriptive design information was collected 1000 primary cultures in external consultation and hospitalization of both institutions of health in period January to May 2009.

Results. In the 1000 primary cultures 789 (79%) were at the Hospital Vicente Corral and 211 (21%) in the Hospital José Carrasco identified 352 (35.2%) positive cultures: Escherichia coli, in both hospitals the highest percentage of samples came from the outpatient clinic, the bacterium Escherichia coli showed increased resistance to TMP + SMX association in 50% of crops, there is resistance to other antibacterial agents: cefepime, nitrofurantoin, ceftriaxone, ceftazidime, ciprofloxacin, imepenem, gentamicin and sulbactam, ranging from 12.8% to 22.2%, respectively. Collection characterized the distribution of frequencies as: age, sex and origin of material for cultivation and antibiogram. . Conclusions. Bacterial resistance patterns are changing and differ between health houses. Bacterial behaviour seems to be determined by abuse of antibiotics.

Key words: Culture media, antibiogram, bacteria, bacterial drug resistance, Escherichia coli.
