Involvement of a plasmid in the invasive ability of Shigella flexneri
TLDR
Data directly demonstrate that this large S. flexneri plasmid encodes or regulates some function(s) required for epithelial cell penetration, as well as demonstrating the role of plasmids in virulence.
Shiga-like toxin-converting phages from Escherichia coli strains that cause hemorrhagic colitis or infantile diarrhea.
TLDR
One of these phages and another Shiga-like toxin-converting phage from an Escherichia coli O26 isolate associated with infantile diarrhea were closely related in terms of morphology, virion polypeptides, DNA restriction fragments, lysogenic immunity, and heat stability, although a difference in host range was noted.
Pathogenesis of Escherichia coli diarrhea.
Abstract Two Escherichia coli strains isolated in Vietnam from American soldiers with diarrhea and acute "colitis" were examined for virulence in both in vitro and in vivo experimental models. Thei...
EPITHELIAL CELL PENETRATION AS AN ESSENTIAL STEP IN THE PATHOGENESIS OF BACILLARY DYSENTERY
TLDR
It was extended to show that the virulent parent possesses the ability to infect and multiply within HeLa cells; furthermore, the organisms are able to penetrate epithelial cells of the guinea pig cornea, causing ulcerative lesions.
Production of Shigella dysenteriae type 1-like cytotoxin by Escherichia coli.
TLDR
Strains of Escherichia coli previously implicated or proven to be causes of diarrhea were examined for production of a toxin similar to that of Shigella dysenteriae type 1 (Shiga), suggesting that Shiga-like toxin may be another heretofore undiscovered factor in the pathogenesis of diarrhea caused by some E. coli strains.
Enteropathogenicity of Aeromonas hydrophila and Plesiomonas shigelloides: prevalence among individuals with and without diarrhea in Thailand
TLDR
Volunteer studies or intestinal biopsies of patients with diarrhea may be required to establish whether A. hydrophila is a gastrointestinal pathogen in humans.
Transmission of acute infectious nonbacterial gastroenteritis to volunteers by oral administration of stool filtrates.
TLDR
From the Laboratories of Infectious Diseases and Clinical Investigation, National Institute of Allergy and Infectious diseases, National Institutes of Health, Bethesda, Maryland; the University of Maryland School of Medicine, Baltimore, Maryland ; and the Walter Reed Army Institute of Medical Research, Washington, D.C.
Pathogenesis of salmonellosis. Studies of fluid secretion, mucosal invasion, and morphologic reaction in the rabbit ileum.
TLDR
Observations suggest that, as is the case in shigellosis, mucosal invasion may be a necessary factor for the intestinal fluid loss in salmonellosis.
