Edema disease caused by a clone of Escherichia coli O147.

DNA microarray-based identification of serogroups and virulence gene patterns of Escherichia coli isolates associated with porcine postweaning diarrhea and edema disease.

Escherichia coli strains causing postweaning diarrhea (PWD) and edema disease (ED) in pigs are limited to a number of serogroups, with O8, O45, O138, O139, O141, O147, O149, and O157 being the most commonly reported worldwide. In this study, a DNA microarray based on the O-antigen-specific genes of all 8 E. coli serogroups, as well as 11 genes encoding adhesion factors and exotoxins associated ...

Aetiologically Relevant Typing of E. Coli Isolates from Diseased Pigs in Switzerland during 2014 and 2015

In this study, 210 intestinal Escherichia (E.) coli isolates from enteropathogenic diseased pigs were screened for their virulence factors (F4, F5, F6, F18, STa, STb, LT, STx2e and intimin) by PCR and serogrouped by slide-agglutination (O8:K87, O45, O138:K81, O139:K82, O141:K85, O147:K89, O157 and O149:K91). In total, 24.8% enterotoxigenic E. coli, 7.1% enteropathogenic E. coli and 5.2% oedema ...

Case Report of Meningoencephalitis in Calves Caused by Escherichia coli

Successful colonoscopic approach in a child with intussusception associated with enterohemorrhagic Escherichia coli O157 infection

The pathogenesis of intussusception caused by enterohemorrhagic Escherichia coli (E. coli) O157 infection is unknown. In our case, colonoscopy was useful for confirming O157 infection. The intussusception was caused by focally damaged edematous mucosa in the cecum. This case helped in elucidating the pathogenesis of the disease.

Phenotype and genotype of Escherichia coli isolated from pigs with postweaning diarrhea in Hungary.

A total of 205 Escherichia coli isolates from 88 diarrheal weanling (4- to 10-week-old) pigs from 59 farms were tested by slide agglutination for K88, K99, F41, and 987P antigens. K88 antigen was detected in 61% of the isolates representing 60% of the pigs and 56% of the farms. K88 antigen was associated with serogroup O149 and 91% of the K88+ isolates. K99, F41, and 987P were not detected. Of ...
