Mechanisms accounting for fluoroquinolone resistance in Escherichia coli clinical isolates.
Fluoroquinolone MICs are increased through the acquisition of chromosomal mutations in the genes encoding gyrase (gyrA and gyrB) and topoisomerase IV (parC and parE), increased levels of the multidrug efflux pump AcrAB, and the plasmid-borne genes aac(6')-Ib-cr and the qnr variants in Escherichia coli. In the accompanying report, we found that ciprofloxacin, gatifloxacin, levofloxacin, and norf...
متن کاملCharacterization of fluoroquinolone resistance among veterinary isolates of avian Escherichia coli.
Fluoroquinolone-resistant avian Escherichia coli isolates from northern Georgia were investigated for gyrA and parC mutations. All isolates contained a mutation in GyrA replacing Ser83 with Leu; seven isolates also contained mutations replacing Asp87 with either Gly or Tyr. Random amplified polymorphic DNA analysis revealed that quinolone-resistant E. coli isolates were genetically diverse.
متن کاملMolecular typing of fluoroquinolone resistant Escherichia coli isolates from patients undergoing prostate biopsy
Background: Escherichia coli (E. coli) is one of the most important infectious agents in patients undergoing prostate biopsy. It belongs to a large family of gram-negative rods, Enterobacteriaceae. This family includes members of the normal flora of the intestine that are only occasionally pathogenic. Recent considerations of rectal colonization with fluoroquinolone-resistant E. coli shows the ...
متن کاملEmergence of fluoroquinolone resistance in Escherichia coli isolates at the department of clinical hematology.
The aim of this study was to evaluate the dependence of Escherichia coli resistance to fluoroquinolones on their use in the outpatients and inpatients in the Hradec Kralove region of the Czech Republic. Data on inpatient fluoroquinolones use were obtained from the database of the Charles University Teaching Hospital Pharmacy and expressed as defined daily dose per 100 beds - days (DBD). Data on...
متن کاملConstruction of an iss deleted mutant strain from a native avian pathogenic Escherichia coli O78: K80 and in vitro serum resistance evaluation of mutant
BACKGROUND: Colibacillosis, caused by different serotypes of avian pathogenic Escherichia coli (APEC), is one of the important diseases in poultry industry. The isolate O78 is the most prevalent serotype of APEC in Iran. One of the APEC virulence factors, increased serum survival (iss) gene, is related to serum resistance. The usual form of colibacillosis in avian is extraintestinal, and serum ...
