Antimicrobial susceptibility of bacteria, isolated from patients treated at Jesenice General hospital in the period between 2004 and 2006
Abstract
Background: Antimicrobial resistance of bacteria is still one of the mayor problems in medicine. In the year 2006, microbiologists of the Institute of Public Health Kranj together with clinicians and pharmacist of Jesenice General Hospital prepared the programm of antimicrobial resistance surveillance of patients treated in the hospital. Some of the results are presented in this article.
Methods: In the retrospective study, bacterial strains, isolated from different samples were analysed. The strains were isolated and studied during the routine work of microbiology laboratory of IPH Kranj in the period between 2004 and 2006.
Results: The most frequently isolated bacteria from haemocultures was Escherichia coli (35.4 %). In the years 2004 and 2006, susceptibility of strains for ciprofloxacin was 95.7 % and 97.2 %, for parenteral cefuroxime (95.7 % and 94.4 %), for cefotaxime and gentamicin in both years 100 %. Susceptibility of E. coli strains from urine samples in patients from the department for internal medicine was in 2004 and 2006 for co-amoxiclav 88.5 % and 70.1 %, for co-trimoxazole 60.3 % and 81.3 %, for cefaclor 94.9 % and 89.7 %, for ciprofloxacin 83.3 % and 82.2 %. Among strains of Staphylococcus aureus, 100 % were sensitive to vancomycin and 99.3 % to linezolid in 2006. Among methicillin susceptible strains, sensitivity to erythromycin, clindamycin and ciprofloxacin lowered slightely in the three years period; in 2006 it was 87.6 %, 90.6 % and 89.1 %. Susceptibility of strains Pseudomonas aeruginosa was in 2006 similar comparing to 2004; it was 92 % for ceftazidime, 75 % for gentamicin, 64.6 % for ciprofloxacin and 96 % for imipenem. Among strains of Acinetobacter spp., sensitivity rate to ciprofloxacin, ceftazidime, piperacillin with tazobactam and gentamicin significantly fell in the year 2005 and stayed low in 2006.
Conclusions: The results of antimicrobial susceptibility surveillance and trends of susceptibility are intended to guide actions for resistance containment.
