Whatever makes them stick – Adhesins of avian pathogenic Escherichia coli [PDF]

Veterinary Microbiology, 2021
Avian pathogenic Escherichia coli (APEC) is associated with extraintestinal infections and the development of colibacillosis, causing high mortality in farm birds and extensive losses in the poultry industry worldwide. The virulence of APEC is a complex phenomenon associated with numerous mechanisms involving a variety of extracellular and ...

Infections with avian pathogenic and fecal Escherichia coli strains display similar lung histopathology and macrophage apoptosis. [PDF]

PLoS ONE, 2012
The purpose of this study was to compare histopathological changes in the lungs of chickens infected with avian pathogenic (APEC) and avian fecal (A(fecal)) Escherichia coli strains, and to analyze how the interaction of the bacteria with avian ...

The genetic network underlying the evolution of pathogenicity in avian Escherichia coli

Frontiers in Veterinary Science, 2023
IntroductionColibacillosis is a worldwide prevalent disease in poultry production linked to Escherichia coli strains that belong to the avian pathogenic E. coli (APEC) pathotype. While many virulence factors have been linked to APEC isolates, no single gene or set of genes has been found to be exclusively associated with the pathotype.

Avian pathogenic Escherichia coli: Epidemiology, virulence and pathogenesis, diagnosis, pathophysiology, transmission, vaccination, and control [PDF]

Veterinary World
Avian pathogenic Escherichia coli (APEC) causes colibacillosis in poultry; this type of bacteria is an extraintestinal pathogen E. coli. Unlike other E. coli pathogen groups, the characteristics of APECs cannot be identified by a single group. Serotyping

Characterization and antimicrobial resistance patterns of Escherichia coli isolated from feces of healthy broiler chickens

Arquivos do Instituto Biológico, 2016
: Avian pathogenic Escherichia coli (APEC) strains are isolated from lesions of poultry presenting colibacillosis, which is a disease that causes either systemic or localized clinical signs. Such strains share many characteristics with E.

The Role of clbF in the Pathogenicity of Avian Pathogenic Escherichia coli

Veterinary Sciences
The genotoxin colibactin, a complex secondary metabolite, targets eukaryotic cell cycle machinery and contributes to neonatal sepsis and meningitis. Avian pathogenic Escherichia coli (APEC) XM, which produces this genotoxin, is an agent of poultry diseases with zoonotic potential.

mcr-Positive Escherichia coli ST131-H22 from Poultry in Brazil

Emerging Infectious Diseases, 2020
Escherichia coli sequence type (ST) 131 is of concern because it can acquire antimicrobial resistance and cause extraintestinal infections. E. coli ST131-H22 sublineage appears capable of being transmitted to humans through poultry.

Characterization of a yjjQ mutant of avian pathogenic Escherichia coli (APEC) [PDF]

Microbiology, 2008
Infections with extraintestinal avian pathogenic Escherichia coli (APEC) cause significant economic losses in the poultry industry worldwide. In a previous study we applied signature-tagged transposon mutagenesis and identified 28 virulence-associated genes in APEC strain IMT5155 (O2 : H5 : K1).
