TLDR
A new adhesive factor was found to occur with greater frequency in EPEC strains and was distinct from type 1 pili and was not inhibited by the presence ofD-mannose.Abstract:
Escherichia coli strains isolated from outbreaks of diarrheal disease were tested for the presence of adhesive factors. Fifty-one of these strains belonged to traditional infantile entero-pathogenic serotypes (EPEC) and 17 belonged to other serotypes. None of these strains were enterotoxigenic and none possessed colonization factors CFA/I or CFA/II, which have been described among strains of enterotoxigenicE. coli (ETEC). EnterotoxigenicE. coli strains from patients with diarrhea and strains which were neither EPEC nor ETEC from subjects without diarrhea were also examined. By means of a tissue culture technique using HEp-2 cells, a new adhesive factor was found to occur with greater frequency in EPEC strains. The adhesive factor was found less frequently in the other groups ofE. coli studied. It was distinct from type 1 pili and was not inhibited by the presence ofD-mannose.read more

Characterization of Enteropathogenic and Enteroaggregative Escherichia coli Isolated from Diarrheal Outbreaks
Jun Yatsuyanagi,Shioko Saito,Hiroyasu Sato,Yoshimichi Miyajima,Ken-ichi Amano,Katsuhiko Enomoto +5 more
TL;DR: Virulence characteristics of diarrheal outbreak-associated Escherichia coli O55: NM, O126:NM, and O111:NM were examined and the contributions of EPEC and EAggEC to the human disease burden in Japan might be significantly greater than is currently appreciated.

TL;DR: Though the pathogenic role and potential virulence factors of arcobacters have to be further examined, the current status of Arcobacter as emerging pathogens remains justified.

Adhesive properties of Enterobacter sakazakii to human epithelial and brain microvascular endothelial cells.

TL;DR: This study examined for the first time the adherence ability of 50 E. sakazakii strains to the two epithelial cell lines HEp-2 and Caco-2, as well as the brain microvascular endothelial cell line HBMEC and found no relationship between the adhesive capacities in E. cloacae and the eventual production of specific fimbriae.

Longus: a long pilus ultrastructure produced by human enterotoxigenic Escherichia coli
TL;DR: A new pilus termed longus produced by ETEC, which can extend for over 20 microns from the cell surface, is described and may represent a highly conserved intestinal colonization factor of ETEC.

Identification of Enteric Pathogens in HIV-Positive Patients with Diarrhoea in Northern India
TL;DR: Stools of all HIV-positive patients with diarrhoea should be investigated to identify aetiologic agents for proper management, and I. belli was the most frequent parasite isolated, followed by Cryptosporidium.

Test for Escherichia coli Enterotoxin Using Infant Mice: Application in a Study of Diarrhea in Children in Honolulu
TL;DR: Use of the infant-mouse test in a study of 37 children with diarrhea in Honolulu revealed no enterotoxin-producing coliform bacteria in the stools, in contrast to studies reported from India, where such strains were found in a large proportion of undifferentiated cases of acute diarrhea in adults.

Plasmid-controlled colonization factor associated with virulence in Esherichia coli enterotoxigenic for humans.
TL;DR: It was demonstrated that E. coli H-10407, but not H10407-, possessed pilus-like surface structures which agglutinated with the specific adsorbed (anti-colonization factor) antiserum, which may play an important and possibly essential role in naturally occurring E coli enterotoxic diarrhea in man.
