Attaching and effacing activities of rabbit and human enteropathogenic Escherichia coli in pig and rabbit intestines.
Three strains of enteropathogenic Escherichia coli (EPEC), originally isolated from humans and previously shown to cause diarrhea in human volunteers by unknown mechanisms, and one rabbit EPEC strainExpand

Biological relationship between F18ab and F18ac fimbriae of enterotoxigenic and verotoxigenic Escherichia coli from weaned pigs with oedema disease or diarrhoea.
Comparative fimbrial expression and adhesion studies were made on enterotoxigenic and verotoxigenic E. coli (ETEC and VTEC) strains isolated from cases of porcine postweaning diarrhoea or oedemaExpand

Rumen contents as a reservoir of enterohemorrhagic Escherichia coli.
We investigated the role of the rumen fermentation as a barrier to the foodborne pathogen, Escherichia coli O157:H7. Strains of E. coli, including several isolates of O157:H7, grew poorly in mediaExpand

Inter‐relationship of sodium, chloride, bicarbonate and acetate transport by the colon of the pig.
1. Net transport of Na, Cl, HCO3 and acetate was examined in the temporarily isolated colon of conscious pigs weighing 46 +/‐ 8 kg. 2. The entire colon absorbs 4.1 ml. H2O, 0.8 m‐equiv Na, 1.3Expand

Comparison of the mechanisms of action of cholera toxin and the heat-stable enterotoxins of Escherichia coli.
The mechanisms which enable cholera toxin (CT) and the Escherichia coli heat-stable enterotoxins (STa and STb) to stimulate intestinal secretion of water and electrolytes are only partiallyExpand

Pathogenic synergism between Treponema hyodysenteriae and other selected anaerobes in gnotobiotic pigs.
Gnotobiotic pigs were orally exposed to various anaerobes at 6 to 9 days of age and similarly inoculated with Treponema hyodysenteriae B204 3 to 6 days later. Watery diarrhea and fecal excretion ofExpand

Purification of the STB enterotoxin of Escherichia coli and the role of selected amino acids on its secretion, stability and toxicity
The methanol-insoluble heat-stable enterotoxin of Escherichia coli (STB) was purified and characterized by automated Edman degradation and tryptic peptide analysis. The amino-terminal residue,Expand

Detection of Heat-Labile Escherichia coli Enterotoxin with the Use of Adrenal Cells in Tissue Culture
Cell-free culture filtrates of heat-labile enterotoxin-producing strains of Escherichia coli are capable of inducing morphological changes and steroidogenesis in monolayer cultures of adrenal cells.Expand

Characterization of the gene encoding heat-stable toxin II and preliminary molecular epidemiological studies of enterotoxigenic Escherichia coli heat-stable toxin II producers.
The gene encoding heat-stable toxin II (STII) was cloned into an Escherichia coli K-12 strain, and its nucleotide sequence was determined. The deduced amino acid sequence indicates that STII isExpand
