background: avian pathogenic escherichia coli (apec), which is the causative agent of colibacillosis, harbors several putative virulence genes. an important trait of apec for both poultry and public health is antibiotic resistance. objectives: in the present study, some potential virulence genes of apecs isolated from northeast of iran and their resistance to the quinolones antibiotics were stu...

To identify traits that predict avian pathogenic Escherichia coli (APEC) virulence, 124 avian E. coli isolates of known pathogenicity and serogroup were subjected to virulence genotyping and phylogenetic typing. The results were analyzed by multiple-correspondence analysis. From this analysis, five genes carried by plasmids were identified as being the most significantly associated with highly ...

Extraintestinal pathogenic Escherichia coli (ExPEC) strains of human and avian origin show similarities that suggest that the avian strains potentially have zoonotic properties. However, the phylogenetic relationships between avian and human ExPEC strains are poorly documented, so this possibility is difficult to assess. We used PCR-based phylotyping and multilocus sequence typing (MLST) to det...

Aim: To know the prevalence of avian pathogenic Escherichia coli (APEC) strains among adult apparently healthy rural chickens slaughtered in Maiduguri, north-eastern Nigeria. Materials and Methods: Cloacal swabs were examined by Gram staining, biochemical tests such as indole, methyl red, Voges-Proskauer and citrate (IMVC) tests and serotype by standard slide agglutination test with antisera ag...

Colibacillosis, caused by avian pathogenic Escherichia coli (APEC), is a significant disease, causing extensive animal and financial losses globally. Because of the significance of this disease, more knowledge is needed regarding APEC's mechanisms of virulence. Here, we present the fully closed genome sequence of a typical avian pathogenic E. coli strain belonging to the serogroup O78.

Avian pathogenic Escherichia coli (APEC) is associated with colibacillosis in poultry. Here, we present the first complete sequence of an APEC strain of the O7:HNT serotype and ST73 sequence type, isolated from a broiler with cellulitis. Complete genomes of APEC with distinct genetic backgrounds may be useful for comparative analysis.

Avian pathogenic Escherichia coli (APEC) bacteria are a significant challenge to the poultry industry. Bacteriophages (phages) have the potential to control APEC strains, increasing animal welfare and economic productivity. Here, we report the isolation of an E. coli-infecting phage, APC_JM3.2, isolated from the cecum of a broiler chicken in Ireland.
