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

Treatment, promotion, commotion: antibiotic alternatives in food-producing animals.
Alternatives to antibiotics are urgently needed in animal agriculture. The form these alternatives should take presents a complex problem due to the various uses of antibiotics in animal agriculture,Expand

Development and competition of digital service platforms: A system dynamics approach
We develop a system dynamics model of platform development that includes two competing platforms and use the model to simulate various development paths by varying different factors that affect how resources accumulate to the platforms. Expand

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

Phenotype and genotype of Escherichia coli isolated from pigs with postweaning diarrhea in Hungary.
A total of 205 Escherichia coli isolates from 88 diarrheal weanling (4- to 10-week-old) pigs from 59 farms were tested by slide agglutination for K88, K99, F41, and 987P antigens. K88 antigen wasExpand

Bovine Immune Response to Shiga-Toxigenic Escherichia coli O157:H7
ABSTRACT Although cattle develop humoral immune responses to Shiga-toxigenic (Stx+) Escherichia coli O157:H7, infections often result in long-term shedding of these human pathogenic bacteria. TheExpand

Plasmid associated with pathogenicity and calcium dependency of Yersinia enterocolitica.
Studies of the virulence and plasmid properties of Yersinia enterocolitica revealed a plasmid, 42.2 +/- 1.1 megadaltons in size, which is associated with the pathogenicity and calcium dependency ofExpand

Persistent Colonization of Sheep byEscherichia coli O157:H7 and Other E. coliPathotypes
ABSTRACT Shiga toxin-producing Escherichia coli (STEC) is an important cause of food-borne illness in humans. Ruminants appear to be more frequently colonized by STEC than are other animals, but theExpand
