Molecular Characteristics of ST1193 Clone among Phylogenetic Group B2 Non-ST131 Fluoroquinolone-Resistant Escherichia coli
Objectives: Sequence type 1193 is emerging as a new, virulent and resistant lineage among fluoroquinolone resistant Escherichia coli (FQrE. coli). In this study, we investigated the prevalence and molecular characteristics of this clone isolated from a Chinese university hospital. Methods: 73 phylogenetic group B2-FQr-non-ST131 isolates were collected from August 2014 and August 2015 at a Chine...
متن کاملQuinolone-resistant uropathogenic Escherichia coli strains from phylogenetic group B2 have fewer virulence factors than their susceptible counterparts.
The prevalence of 31 virulence factors was analyzed among nalidixic acid-susceptible and -resistant Escherichia coli strains from phylogenetic group B2. Hemolysin, cytotoxic necrotizing factor 1, and S and F1C fimbriae genes were less prevalent among nalidixic acid-resistant E. coli strains. Quinolone resistance may be associated with a decrease in the presence of some virulence factors.
متن کاملZinc oxide nanoparticle reduced biofilm formation and antigen 43 expressions in uropathogenic Escherichia coli
Objective(s): This study aimed to investigate the effect of zinc oxide nanoparticles (ZnO-np) on biofilm formation and expression of the flu gene in uropathogenic Escherichia coli (UPEC) strains. Materials and Methods: Minimum inhibitory concentration (MIC) of ZnO-np was determined by agar dilution method. The effect of MIC and sub-MIC concentrations of ZnO-np on biofilm formation were determin...
متن کاملFimbriae of Uropathogenic Escherichia coli Mediate Biofilm Formation
Uropathogenic Escherichia coli (UPEC) is the primary cause of urinary tract infection (UTI) in the developed world. The major factors associated with virulence of UPEC are fimbrial adhesins, which mediate attachment to specific receptors, enhance persistence and trigger innate host responses. UPEC produce a range of fimbrial adhesins, with type 1 and P fimbriae of the chaperone-usher subclass b...
متن کاملIntegrons and antibiotic resistance in phylogenetic group B2 Escherichia coli.
It has been reported that Escherichia coli B2 phylogenetic group strains are more susceptible to antibiotics, especially to quinolones, and tend to carry less integrons than other phylogenetic groups in commensal environments. To gain a better understanding of the relationships between antibiotic resistance, integrons, and phylogenetic groups in an environment with high antibiotic selective pre...
