The presence of spina bifida occulta significantly affects the response to medical treatment in patients with PMNE. Thus, verifying spina bifida occulta status in PMNE can facilitate prognostic predictions about the response to medical treatment.
ÖZETAmaç: Bu çalışmada, İstanbul'da bir özel hastanede toplum kökenli üriner sistem enfeksiyonlarından izole edilen Escherichia coli suşlarında antimikrobiyal duyarlılıklarının belirlenmesi amaçlanmıştır. Results: A total of 191 E. coli strains isolated from urine cultures which were processed between January 2008 and December 2008 in the clinical laboratory, were included in the study. Identification of bacteria and antibiotic susceptibility tests were performed by disk diffusion and automated system. Of E. coli strains, 14.6% (n=28) were found positive for ESBL. The resistance rates of E. coli strains were found as follows; 12.4% for nitrofurantoin, 40% for trimethoprim/sulfamethoxazole (TMP-SMX), 19.8% for ciprofloxacin and 19.2% for ceftriaxon.Conclusion: Empirical therapy should be based on local antimicrobial resistance monitoring in order to optimize the use of these drugs.

The presence of extended spectrum beta-lactamases (ESbetaLs) in 129 Escherichia coli and 128 Klebsiella pneumoniae strains was determined with the E test. beta-lactamases were detected in 66 (51.2%) of E.coli and 107 (83.6%) of K. pneumoniae by the nitrocefin disk method. Putative ESbetaL production was observed in 15.5% of E. coli and 55.5% of K. pneumoniae with the E test. Among the putative ESbetaL-producer strains 11 were found to be susceptible to ceftizoxime, 6 to ceftazidime, 2 to ceftriaxone, cefotaxime and aztreonam, and one to cefoperazone according to the disk diffusion test. All putative ESbetaL-producers were resistant to cefodizime, thus it may be a good indicator of the presence of mainly TEM-type ESbetaL. The E test was also found to be practicable for the detection of ESbetaLs in clinical laboratory. Further studies are needed to clarify whether ESbetaL can be identified reliably in species that, in addition to plasmid mediated ESbetaL production, chromosomally encoded AmpC beta-lactamases and other class A ESbetaLs by disk diffusion test.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
