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

Expression of the Bundle-Forming Pilus by Enteropathogenic Escherichia coli Strains of Heterologous Serotypes
TL;DR: The use of brucella agar supplemented with 4.5 mM sodium bisulfite resulted in a higher detection of BfpA-producing EPEC.

Self-transmissible R plasmids encoding CS31A among human Escherichia coli strains isolated from diarrheal stools
TL;DR: A horizontal transfer between E. coli and K. pneumoniae strains is suggested because of a similar linkage between these genes in Klebsiella pneumoniae strain which produced CF29K, a CS31A-like antigen.

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.
