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

HEp-2 cell adherence and Vero cell cytotoxin production by EPEC strains isolated from children with diarrhoea in New Zealand
TL;DR: The results suggest that if EPEC strains are to be considered as a cause of diarrhoea, the search for new virulence factors must be extended.

Modern diagnosis (with molecular tests) of acute infectious diarrhea.
TL;DR: With a scanning laser system, the results of enteric PCRs will be used to identify enteric pathogens on a routine basis in clinical and public health laboratories.

The role of pathogenic Escherichia coli in the etiology of veal calf hemorrhagic enteritis
TL;DR: There was no correlation between STa production and K99 pili expression among the enterotoxigenic E. coli isolates that were recovered from veal calves, which may indicate the emergence of K99-negative ETEC, probably as a result of the wide use of K 99-based vaccines.

Differences between the LPS cores in adherent and non-adherent strains of enteropathogenic Escherichia coli 0119
TL;DR: Adherent enteropathogenic Escherichia coli 0119 strains had a larger lipopolysaccharide core than non-adherent strains, although the O-chains were identical.

TL;DR: The results demonstrated that Staphylococcus aureus and Pseudomonas aeruginosa may act differently when they are the protagonists of infections and may occur in different clinical condition, and many of the observed differences are statistically significant.

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.
