Virulence characteristics and antimicrobial susceptibility of uropathogenic Escherichia coli strains.
Eight virulence factors associated with uropathogenic Escherichia coli (UPEC) were investigated in 204 clinical isolates of E. coli recovered from urine cultures at counts ≥10(5). The bacteria were classified into two groups according to the number of leukocytes in urine samples from which they were isolated: group I ≤8 leukocytes/hpf, 104 strains; group II >8 leukocytes/hpf, 100 strains....
متن کاملMouse 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 کاملVirulence properties and clonal structures of strains of Escherichia coli O119 serotypes.
A total of 110 Escherichia coli strains of serogroup O119 were examined for the presence of virulence properties characteristic of enteropathogenic E. coli (EPEC). Three virulence patterns were distinguished based on the detection of a chromosomal gene mediating intimate attachment (eaeA) and plasmid DNA involved in localized adherence (EAF and bfpA). The first pattern, represented by strains w...
متن کاملVirulence properties of enterotoxigenic Escherichia coli O8: KX105 strains isolated from diarrheic piglets.
Twenty-two enterotoxigenic Escherichia coli (ETEC) O8:KX105 strains isolated from 1- to 7-week-old diarrheic piglets were examined for virulence properties. Thirteen strains caused acute watery diarrhea in orally infected, colostrum-deprived newborn piglets, whereas the remaining nine did not. The enteropathogenic strains colonized the small intestine, albeit with lower intensity than classical...
متن کاملEscherichia coli serogroup O111 includes several clones of diarrheagenic strains with different virulence properties.
Genetic variation among isolates of Escherichia coli O111 obtained mostly from patients with diarrhea in Brazil was assessed by multilocus enzyme electrophoresis to characterize chromosomal genotypes and by gene probes and adherence assays to characterize virulence properties. Among the 152 isolates, we resolved 16 distinct electrophoretic types (ETs), which differed on average at 40% of the en...
