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

Adhesion, autoaggregation and hydrophobicity of six Lactobacillus strains.
TL;DR: The findings indicated that one Lactobacillusstrain expressed broad antibacterial activities against a group of bacterial pathogens and along 2 other strains exhibited ability to adhere to epithelial cells as shown by aggregation, coaggregationand hydrophobicity, indicating that such isolates can be good candidates for probiotic use.

TL;DR: Observations suggest that these probiotic strains can serve as alternative therapeutics against MDR-EAEC-associated infections in humans and animals.

TL;DR: The eae gene was detected more frequently in strains isolated from HUS patients than in those associated with cases of diarrhoea; beta-intimin was the most common intimin subtype in strains isolate from both groups of patients.

TL;DR: Serotyped E. coli strains isolated in a yearlong case-control study of infantile diarrhea in Bangkok, Thailand, were examined for adherence to HeLa cells and for hybridization with the enteropathogenic E.coli adherence factor, the F1845, and the enteroaggregative E.ccoli DNA probes to determine the association of tissue culture-adherent Escherichia coli with diarrhea.

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.
