Distribution of virulence associated genes in isolated Escherichia coli from avian colibacillosis

BACKGROUND: Colibacillosis is one of the most prevalentdiseases in the world that causes multimillion-dollar annuallosses. OBJECTIVES: In order to evaluate molecular epidemiologyof some virulence associated factors in Escherichia coli,isolated from poultry, the presence of iut A, iss, hly F, omp T, iroN, afa, sfa (S)and pap G (II) were investigated by multiplex PCRassay. METHODS: Two hundred th...

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...

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...

Detection of TEM Gene in Clinical Isolates of Pseudomonas aeruginosa and Escherichia coli in Isfahan province (from 2018)

Background: The isolation of the TEM gene in Pseudomonas aeruginosa and Escherichia coli and the antibiotic resistance pattern provides useful information on the epidemiology and factors involved in these infections. Aim: The aim of this study was to evaluate antibiotic resistance and abundance of a beta-lactamase gene (TEM) in P.aeruginosa and E.coli isolated from clinical specimens by the po...

ECOR phylotyping and determination of virulence genes in Escherichia coli isolates from pathological conditions of broiler chickens in poultry slaughter-houses of southeast of Iran

Avian pathogenic Escherichia coli (APEC) are responsible for wide ranges of extra-intestinal diseases in poultry including colibacillosis, cellulitis, coligranuloma and yolk sac infection. Numbers of virulence are considered important in the pathogenicity of these diseases. The aims of the present study were phylogenetic typing and virulence genes detection in Escherichia coli </em...
