Physiology and pathogenicity of cpdB deleted mutant of avian pathogenic Escherichia coli

Research in Veterinary Science, 2017
Avian colibacillosis is one of the most common infectious diseases caused partially or entirely by avian pathogenic Escherichia coli (APEC) in birds. In addition to spontaneous infection, APEC can also cause secondary infections that result in greater severity of illness and greater losses to the poultry industry.

Biofilm Formation by Avian Pathogenic Escherichia coli is Not Related to In Vivo Pathogenicity

Current Microbiology, 2018
Avian pathogenic Escherichia coli (APEC) is one of the pathogens that most concerns the poultry industry worldwide due to the economic losses it can cause. APEC persistence and survival, both in the environment and in the host, may be a consequence of biofilm-producing capabilities. The aim of this study was to evaluate APEC strains' biofilm production

Characterization of avian pathogenic Escherichia coli isolated in eastern China

Gene, 2016
In order to investigate the biological characteristics of avian pathogenic Escherichia coli (APEC) isolated in eastern China, a total of 243 isolates were isolated from diseased poultry on different farms during the period from 2007 to 2014. These isolates were characterized for serogroups (polymerase chain reaction and agglutination), the presence of ...

Genetic relationships among pathogenic strains of avian Escherichia coli

Infection and Immunity, 1988
Genetic relationships among 79 strains of Escherichia coli, isolated mostly from diseased chickens, were estimated on the basis of allelic variation at 15 enzyme-encoding loci, determined by multilocus enzyme electrophoresis. All 15 loci were polymorphic, with an average of 4.1 allelic states per locus.

[Avian pathogenic Escherichia coli (APEC)].

Berliner und Munchener tierarztliche Wochenschrift, 2004
Infections with avian pathogenic Escherichia coli (APEC) cause colibacillosis, an acute and mostly systemic disease resulting in significant economic losses in poultry industry worldwide. Avian colibacillosis is a complex syndrome characterized by multiple organ lesions with airsacculitis and associated pericarditis, perihepatitis and peritonitis being

Oxidative stress response in avian pathogenic Escherichia coli

Research in Veterinary Science
Avian pathogenic Escherichia coli (APEC) leads to significant economic losses in the poultry industry worldwide and restricts the development of the poultry industry. Oxidative stress, through the production of reactive oxygen species (ROS), damage iron‑sulfur (FeS) clusters, cysteine and methionine protein residues, and DNA, and then result in ...

[Avian pathogenic Escherichia coli (APEC)].

Tijdschrift voor diergeneeskunde, 2003
Escherichia coli infections are being increasingly detected among poultry flocks, indicating the growing importance of this pathogen to the industry. The infection begins as a respiratory infection of the trachea, followed by colonization of the air sacs and lungs, from where it invades the blood-stream, leading to infection of the deeper organs (liver,

Adherence Pili in Avian Strains of Escherichia coli: Effect on Pathogenicity

Avian Diseases, 1984
Several pathogenic strains of Escherichia coli were isolated from chickens and turkeys with severe colisepticemia. Electron microscopic examination showed that all these strains had thin pili (fimbriae) when grown at 37 C but not at 18 C. These pili facilitated adherence of the bacteria to chick tracheal epithelial cells both in vitro and in vivo.

The luxS gene functions in the pathogenesis of avian pathogenic Escherichia coli

Microbial Pathogenesis, 2013
Avian pathogenic Escherichia coli (APEC) causes avian colibacillosis, the most significant infectious bacterial disease of poultry worldwide. LuxS, the product of the luxS gene, mediates the quorum sensing (QS) mechanism. This involves the production of autoinducer-2 (AI-2), which regulates important physiological traits and a variety of adaptive ...

Characteristics associated with pathogenicity of avian septicaemic Escherichia coli strains

Veterinary Microbiology, 1994
Seventeen strains of E. coli, isolated from chickens with colisepticaemia, were studied with respect to their pathogenic characteristics including: serum resistance, toxin production, pathogenicity for one-day-old chicks, colicin production, adherence to and invasiveness of HeLa cells, plasmid DNA profile and SDS-PAGE electrophoresis of membrane ...
