Prevalence of virulence factors in Escherichia coli isolated from healthy animals and water sources in Brazil.
The aim of this work was to verify the presence of seven virulence factors (ST, LT, eae, stx(1), stx(2), INV and EAEC) among Escherichia coli strains isolated from healthy humans, bovines, chickens, sheep, pigs and goats, from two sewage treatment plants and from the Tietê River. We have found a high prevalence of eae, stx(1) and stx(2) in ruminants. The EAEC gene was only found in humans and s...
متن کاملGenetic Investigation of Beta-Lactam Associated Antibiotic Resistance Among Escherichia Coli Strains Isolated from Water Sources
Background Antimicrobial resistance is an important factor threatening human health. It is widely accepted that antibiotic resistant bacteria such as Escherichia coli (E. coli) released from humans and animals into the water sources, can introduce their resistance genes into the natural bacterial community. Objective The aim of this study was to investigate the prevalence of blaTEM, blaCTX, b...
متن کاملPrevalence of Virulence Genes of Escherichia Coli O157:H7 Isolated from Patients with Urinary Tract Infections in Shiraz, Iran
Abstract Background and Objective: Escherichia coli O157:H7 is one of the most well-known pathogenic bacteria worldwide that can develop severe diseases such as hemolytic uremic syndrome (HUS). This study aimed to assess the prevalence of virulence genes of E. coli O157:H7 in patients with suspected urinary tract infections (UTIs). Material and Methods: This cross-sectional study was co...
متن کاملDistribution 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...
متن کاملDetection of eaeA, hlyA, stx1 and stx2 genes in pathogenic Escherichia coli isolated from broilers affected with colibacillosis
Background: Foodborne outbreaks associated with shiga toxin-producing Escherichia coli (STEC) have been well documented worldwide. STECs are major causative agents of gastroenteritis in humans that may be complicated by hemorrhagic colitis (HC), hemolytic uremic syndrome (HUS), and thrombotic thrombocytopenia purpura (TTP). OBJECTIVES: The aim of this study was to investigate the presence of vi...
