Mouse Virulence of Human, Systemic, Pathogenic Escherichia coli Strains.
Strains of Escherichia coli isolated from systemic infections of humans exhibited marked intraperitoneal and intracerebral virulence for mice. This marked virulence was not exhibited by enteropathogenic strains.

متن کاملPhylogenetic typing and molecular detection of virulence factors of avian pathogenic Escherichia coli isolated from colibacillosis cases in Japanese quail
Colibacillosis caused by avian pathogenic Escherichia coli (APEC) is an economic threat to the poultry industry throughout the world. Some of the virulence genes may enhance the ability of E. coli isolates to grow in the tissues of broilers. The APEC strains are assigned to a few distinct phylogenetic groups. The purpose of the present study was to detect the virulence genes a...
متن کاملHemolytic porcine intestinal Escherichia coli without virulence-associated genes typical of intestinal pathogenic E. coli.
Testing 1,666 fecal or intestinal samples from healthy and diarrheic pigs, we obtained hemolytic Escherichia coli isolates from 593 samples. Focusing on hemolytic E. coli isolates without virulence-associated genes (VAGs) typical for enteropathogens, we found that such isolates carried a broad variety of VAGs typical for extraintestinal pathogenic E. coli.
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</...
