Enteropathogenic Escherichia coli enteritis: evaluation of the gnotobiotic piglet as a model of human infection.
The pathogenicity of classical enteropathogenic Escherichia coli strains of human origin was investigated in gnotobiotic piglets. One to two day old piglets in groups of four were infected perorally with approximately 10(8) colony forming units of one of eight enteropathogenic E coli strains or a non-pathogenic control strain. Animals were necropsied 24 or 48 hours after infection and their int...
متن کاملEscherichia coli gastro-enteritis.
Mild gastro-intestinal upset is common in babies, but severe disease is not now the scourge it formerly was, and part of the great improvement in infantile mortality is due to its decline in the twentieth century. The reasons for this are not clear, and many theories have been advanced. Formerly, a considerable number of cases of gastro-enteritis were thought to be due to dietetic, that is to s...
متن کاملEmerging Enteropathogenic Escherichia coli Strains?
Escherichia coli strains of nonenteropathogenic serogroups carrying eae but lacking the enteropathogenic E. coli adherence factor plasmid and Shiga toxin DNA probe sequences were isolated from patients (children, adults, and AIDS patients) with and without diarrhea in Brazil. Although diverse in phenotype and genotype, some strains are potentially diarrheagenic.
متن کاملClonal Relatedness of Enterotoxigenic and Enteropathogenic Escherichia coli Isolates from Diverse Human, Foods and Calf Sources
Background: Foodborne infection caused by EnterotoxigenicEscherichia coli (ETEC) and Enteropathogenic Escherichia coli (EPEC) is one of the major health problems, particularly in the developing countries. Therefore, it is vital to identify the origin of food contamination to plan control strategies efficiently. Method: A tota...
متن کاملEnteropathogenic Escherichia coli O157 Strains from Brazil
We describe two serogroup O157 Escherichia coli strains from Brazilian infants with diarrhea. A variety of assays indicate that these strains belong to the enteropathogenic, not the enterohemorrhagic, pathotype. These strains possess a novel bfpA allele encoding the type IV pilin characteristic of typical enteropathogenic E. coli strains. Our results emphasize the pitfalls of classifying pathog...
