Occurrence of Escherichia coli in captive psittaciformes: antimicrobial susceptibility and virulence genes

Virulence characteristics and antimicrobial susceptibility of uropathogenic Escherichia coli strains.

Eight virulence factors associated with uropathogenic Escherichia coli (UPEC) were investigated in 204 clinical isolates of E. coli recovered from urine cultures at counts ≥10(5). The bacteria were classified into two groups according to the number of leukocytes in urine samples from which they were isolated: group I ≤8 leukocytes/hpf, 104 strains; group II >8 leukocytes/hpf, 100 strains....

Virulence genes and antimicrobial susceptibility of Escherichia coli taken from women with vaginitis in Talca, Chile.

INTRODUCTION Vaginitis is one of the most common reasons women visit a gynecologist. Escherichia coli has been isolated from women with vaginitis, but its role as a vaginal infection aetiological agent is controversial. This study aimed to detect virulence genes and determine the antimicrobial susceptibility of E. coli strains isolated from monomicrobial and polymicrobial cultures collected fro...

Frequency of selected virulence-associated genes in intestinal and extra-intestinal Escherichia coli isolates from chicken

Background: Although Escherichia coli (E. coli)is a part of intestinal normal microflora of warm-blooded animals, includingpoultry, outbreaks occur in poultry raised below standard sanitation and duringthe course of respiratory or immunosuppressive diseases. Avian pathogenic E.coli (APEC) harbors several genes associated with virulence andpathogenicity. APEC strains are responsible for some dis...

Study of antimicrobial susceptibility and plasmid analysis of Escherichia coli in Iran, Urmia

Prevalence of virulence genes in Escherichia coli isolates of patients with UTI

Abstract Background and Objective: Urinary tract infection refers to the presence of microbial pathogens in the urinary tract and is one of the most common infections in outpatient and hospitalized patients. A wide variety of extra-intestinal infections in humans and animals are caused by the extracellular strains of Escherichia coli (EXPEC). Materials and methods:  A total of 50 E. coli iso...
