The purpose of this study is to detect the frequency of fluoroquinolone-resistant Escherichia
coli (E. coli) clinical isolates from hospital-acquired infection (HAI) compared to community …

Background Fluoroquinolone (FR) resistant Escherichia coli infection has become a global
problem. The FR resistance usually occurs mainly due to specific point of mutations within …

Since the use of fluoroquinolone antibiotic in clinical practice was introduced about two
decades ago, quinolone-resistant E. coli strains are being isolated with increasing …

Fluoroquinolones are the drug of choice for most of the infections caused by Escherichia
coli, and their indiscriminate use has resulted in increased selective pressure for antibiotic …

Sixty-five ciprofloxacin-resistant clinical Escherichia coli isolates were collected from a
Taiwan Medical Center from December 1998 to February 1999. All 65 clinical isolates were …

Fig. 1. Dendrogram of 63 clinical E. coli isolates based on PFGE results. Strains were
clustered by UPGMA. Correlation: Bands, Jaccard (tolerance 1.0%, optimization value 0.5 …

Background: Urinary tract infections (UTIs) are one of the most common infections seen in
community practice. Overall, E. coli is responsible for the majority (50% to 80%) of UTIs …

Background Fluoroquinolone resistant Escherichia coli isolates have become an important
challenge in healthcare settings in Iran. In this study, we have determined Fluoroquinolone …

Materials and Methods: Thirty seven isolates from patients with burn wounds and 20 isolates
from blood, urine and sputum specimen were collected. Minimum Inhibitory Concentrations …

We searched for the mutations involved in high-level fluoroquinolone resistance
(ciprofloxacin MIC≥ 8 μg/ml) of 11 clinical isolates of Escherichia coli. trans …
