Genetic characterization and virulence of enterotoxigenic Escherichia coli mutants which have lost virulence genes in vivo.

چکیده
Loss of K99 and STaP genes from enterotoxigenic Escherichia coli 431 during infection occurred by either plasmid curing or plasmid deletion. These mutants expressed the F41 adhesion and colonized neonatal pigs, but only those mutants that retained STaP caused diarrhea with significant weight loss.

Molecular characterization of enterotoxigenic Escherichia coli isolated from neonatal calves diarrhea
Enterotoxigenic Escherichia coli (ETEC) produces different virulence factors allowing the bacterium to colonize and develop watery diarrhea. Proteomics studies have also introduced new protein belonging to the secretion pathways, antigen 43 (Ag43), which plays important role in E. coli pathogenesis. The objective of this study was to investigate O-types and virulence factors o...
متن کاملGenotypic and phenotypic characterization of enteroaggregative Escherichia coli (EAEC) isolates from diarrheic children: An unresolved diagnostic paradigm exists
Objective(s): The enteroaggregative Escherichia coli (EAEC) has been one of the most intriguing emerging bacterial pathogens in children that occur both in developing countries and the industrial world. Although various phenotypic and genotypic based protocols have been suggested for diagnosis of EAEC, they are not conclusive or practical to be used in most clinical la...
متن کاملIn vitro assessment of pathogenicity and virulence encoding gene profiles of avian pathogenic Escherichia coli strains associated with colibacillosis in chickens
Background: Avian pathogenic Escherichia coli (APEC) strains have been associated with various disease conditions in avian species due to virulence attributes associated with the organism. Aims: This study was carried out to determine the in vitro pathogenic characteristics and virulence encoding genes found in E. coli strains associated with colibacillosis in chickens. Methods: Fifty-two stock...
متن کاملExtra intestinal pathogenic Escherichia coli from human and avian origin: Detection of the most common virulence-encoding genes
Pathogenic Escherichia coli strains cause a wide range of extra intestinal infections including urinary tract infection in humans and colibacillosis in poultry. They are classified into uropathogenic E. coli (UPEC) and avian pathogenic E. coli (APEC) with genetic similarities and variations. Their pathogenicity is related to the virulence-encoding genes like sfa</...
