A total of 318 Escherichia coli isolates obtained from different food-producing animals affected with colibacillosis between 2001 and 2006 were subjected to phylogenetic analysis: 72 bovine isolates, 89 poultry isolates and 157 porcine isolates. Overall, the phylogenetic group A was predominant in isolates from cattle (36/72, 50%) and pigs (101/157, 64.3%) whereas groups A (44/89, 49.4%) and D (40/89, 44.9%) were predominant in isolates from poultry. In addition, group B2 was not found among… Expand
Phylogenetic group determination of Escherichia coli isolated from broilers and layers with colibacillosis.
TLDR
Overall, the phylogenetic Determination revealed the B2 groups as predominant isolates in diseased birds, whereas the A group was apparently predominant in healthy birds. Expand
Logenetic grouping and antimicrobial resistance profiles of Escherichia coli isolated from calves in Xinjiang, China.
TLDR
It is demonstrated that prevalent multi-drug resistance and high level of antimicrobial resistance genes exist among E. coli from Xinjiang diarrheic calves and pose a potential public health concern. Expand
Phylogenetic grouping and virulence gene profiles of Escherichia coli isolated from chicken
TLDR
E. coli isolates from chicken in this study appear to be derived from commensal strains and may relate to environmental predispose factors especially stress factors in the host to establish infection. Expand
Phylogenetic analysis of Escherichia coli isolated from broilers with colibacillosis based on gyrA gene sequences.
TLDR
The phylogenetic results based on gyrA gene sequences from multiplex PCR revealed that E. coli phylogenetic grouping was in accordance with the clusters obtained in the phylogenetic tree and may constitute a pertinent phylogenetic marker for E.ccoli and related taxa. Expand
Phylogenetic grouping, epidemiological typing, analysis of virulence genes, and antimicrobial susceptibility of Escherichia coli isolated from healthy broilers in Japan
TLDR
The authors' results indicated that E. coli isolates inhabiting the intestines of healthy broilers pose a potential risk of causing avian colibacillosis. Expand
Phylogenetic analysis of Escherichia coli isolates from healthy and diarrhoeic calves in Mashhad, Iran.
TLDR
Evaluating the influence of diarrhoea on the genetic composition of E. coli populations isolated from calves found no significant difference between healthy and diarrhoeic calves for other phylogroups, except for phylogroup B1 which was higher in healthy calves. Expand
Diversity of plasmid replicons encoding the bla(CMY-2) gene in broad-spectrum cephalosporin-resistant Escherichia coli from livestock animals in Japan.
TLDR
The findings suggest that the bla(CMY-2) gene is a key player in BSC-resistant E. coli isolates and that coselection is unlikely to be associated with the abundance of bla (CMY) plasmids, except for IncA/C plasmid. Expand
Characteristics of Escherichia coli isolated from broiler chickens with colibacillosis in commercial farms from a common hatchery
TLDR
The data suggest that E. coli strains with identical pulsotypes had been caused the incidences of colibacillosis and that the antimicrobial resistance genes on conjugative plasmids and those integrated into the chromosome may be spread among avian pathogenic E. Escherichia coli strains in multiple farms. Expand
Phylogenetic Grouping and Phenotypic Detection of Extended-Spectrum β-Lactamases Among Escherichia coli From Calves and Dairy Cows in Khuzestan, Iran
TLDR
There was no statistically significant relationship between the phylogenetic group and the production of ESBLs (P = 0.11), and further large scale investigations are necessary to control the antibiotic resistance in the human and animal foodstuff. Expand
The distribution of beta lactamase genes in Escherichia coli phylotypes isolated from diarrhea and UTI cases in northwest Iran.
TLDR
The correct choice of effective antibiotic policy is needed to limit the spread of antibiotic resistance in bacteria and determine the phenotypic and genotypic characteristics of ESBLS produced by E. coli isolate taken from patients with diarrhea and urinary tract infections in northwest Iran.

National monitoring for antimicrobial resistance among indicator bacteria isolated from food-producing animals in Japan.
TLDR
Overall, the isolates from cattle and layer chickens showed a lower incidence of resistance to almost all antimicrobials studied compared with those from pigs and broiler chickens, which did not vary from year to year during the investigation period. Expand
Antimicrobial susceptibility of pathogenic Escherichia coli isolated from sick cattle and pigs in Japan.
TLDR
The results can be considered helpful for adequate selection and prudent use of antimicrobial agents for several types of colibacillosis. Expand
Absence of Escherichia coli Phylogenetic Group B2 Strains in Humans and Domesticated Animals from Jeonnam Province, Republic of Korea
TLDR
E. coli strains in phylogenetic group B2 were rarely found in humans and domesticated animals in Jeonnam Province, South Korea, and that the majority of strains containing virulence genes belonged to phylogenetics group B1 and were isolated from beef cattle. Expand
Intestine and Environment of the Chicken as Reservoirs for Extraintestinal Pathogenic Escherichia coli Strains with Zoonotic Potential
TLDR
Multilocus sequence typing data revealed that most strains that were virulent in chicken infection experiments belonged to sequence types that are almost exclusively associated with extraintestinal diseases not only in birds but also in humans, supporting the hypothesis that not the ecohabitat but the phylogeny of E. coli strains determines virulence. Expand
Escherichia coli phylogenetic group determination and its application in the identification of the major animal source of fecal contamination
TLDR
The analysis of the E. coli population structure can be useful as a supplementary bacterial source tracking tool and identifies the major source of fecal contamination of a pool of strains instead of a unique strain. Expand
Cephalosporin resistance mechanisms in Escherichia coli isolated from raw chicken imported into the UK.
TLDR
Raw chicken imported into the UK from South America commonly carries ESBL-producing E. coli, but is not a significant source for the ST131 clone or for the CTX-M-15 ESBL. Expand
Escherichia coli Producing CTX-M-2 β-Lactamase in Cattle, Japan
TLDR
Findings suggest that CTX-M-2 producers might have originated from cattle through the use of cephalosporins such as ceftiofur and that cattle could be a reservoir of CTX–producing E. coli. Expand
Phylogenetic distribution of extraintestinal virulence-associated traits in Escherichia coli.
TLDR
The distribution patterns of papA variants and other VFs suggested multiple horizontal transfer events and new insights into the phylogenetic origins of extraintestinal VFs in E. coli are provided. Expand
Comparison of Escherichia coli isolates implicated in human urinary tract infection and avian colibacillosis.
TLDR
The potential for APEC to act as human UPEC or as a reservoir of virulence genes for UPEC should be considered, but significant differences in the prevalence of the traits occurred across the two groups, suggesting that if APEC are involved in human urinary tract infections, they are not involved in all of them.

Extraintestinal pathogenic Escherichia coli O1:K1:H7/NM from human and avian origin: detection of clonal groups B2 ST95 and D ST59 with different host distribution
TLDR
Clonal group B2 O1:K1:H7/NM ST95, detected in strains of animal and human origin, recovered from different dates and geographic sources, provides evidence that some APEC isolates may act as potential pathogens for humans and, consequently, poultry as a foodborne source, suggesting no host specificity for this type of isolates.
