Quantitation of the adherence of an enteropathogenic Escherichia coli to isolated rabbit intestinal brush borders.
Two assays were developed to quantitate the adherence of an Escherichia coli strain (RDEC-1) known to colonize the mucosal surface of the small intestine of rabbits to brush borders isolated from rabbit intestinal epithelial cells. In the first assay, the mean adherence per rabbit brush border was determined by counting the number of organisms adhering to each of 40 brush borders under phase mi...
متن کاملCharacteristics of binding of Escherichia coli serotype O157:H7 strain CL-49 to purified intestinal mucin.
Purified rat intestinal mucin was used as a model mucin to study the binding of Escherichia coli serotype O157:H7, a human pathogen associated with outbreaks of hemorrhagic colitis and hemolytic uremic syndrome. Of six O157:H7 strains, only one strain (designated CL-49) bound to rat (and other) intestinal mucins by a specific and saturable process. Binding was observed only after the bacteria w...
متن کاملBinding of collagens to an enterotoxigenic strain of Escherichia coli.
An enterotoxigenic strain of Escherichia coli, B34289c, has been shown to bind the N-terminal region of fibronectin with high affinity (G. Fröman, L. M. Switalski, A. Faris, T. Wadström, and M. Höök, J. Biol. Chem. 259:14899-14905, 1984). We now report that this strain also binds collagen. The binding of 125I-labeled type II collagen to bacteria was time dependent and reversible. Bacteria expre...
متن کاملEnterotoxigenic Escherichia coli--an overview.
Enterotoxigenic Escherichia coli is an important cause of traveler's diarrhea and diarrheal illnesses in children in the developing world. In this presentation we will focus on the main virulence attributes of this pathogenic category of E. coli, and discuss the evolution of studies conducted in our laboratory.
متن کاملAncestral lineages of human enterotoxigenic Escherichia coli.
Enterotoxigenic Escherichia coli (ETEC) is a common cause of diarrhea among children living in and among travelers visiting developing countries. Human ETEC strains represent an epidemiologically and phenotypically diverse group of pathogens, and there is a need to identify natural groupings of these organisms that may help to explain this diversity. Here, we sought to identify most of the impo...
