dnaX36 mutator of Escherichia coli: effects of the tau subunit of the DNA polymerase III holoenzyme on chromosomal DNA replication fidelity. [PDF]

, 2011
The Escherichia coli dnaX36 mutant displays a mutator effect, reflecting a fidelity function of the dnaX-encoded τ subunit of the DNA polymerase III (Pol III) holoenzyme.

Detection of cytotoxic necrotizing factor types 1 and 2 among fecal Escherichia coli isolates from brazilian children with and without diarrhea

Memorias do Instituto Oswaldo Cruz, 2004
The enteropathogenic role of cytotoxic necrotizing factor (CNF)-producing Escherichia coli was investigated by searching cnf genes among 2074 isolates from 200 children with and 200 without acute diarrhea in Brazil.

SbcCD regulation and localization in Escherichia coli [PDF]

, 2007
The SbcCD complex and its homologues play important roles in DNA repair and in the maintenance of genome stability. In Escherichia coli, the in vitro functions of SbcCD have been well characterized, but its exact cellular role remains elusive.

Adhesins as Targets for Vaccine Development

Emerging Infectious Diseases, 1999
Blocking the primary stages of infection, namely bacterial attachment to host cell receptors and colonization of the mucosal surface, may be the most effective strategy to prevent bacterial infections. Bacterial attachment usually involves an interaction

Differential Afa/Dr Fimbriae Expression in the Multidrug-Resistant Escherichia coli ST131 Clone

mBio, 2022
Many antibiotic resistant uropathogenic Escherichia coli (UPEC) strains belong to clones defined by their multilocus sequence type (ST), with ST131 being the most dominant.

Characterization of the Adhesin of Escherichia coli F18 Fimbriae [PDF]

Infection and Immunity, 2001
ABSTRACT Previous research has suggested that the adhesin encoded by the F18 fimbrial operon in Escherichia coli is either the FedE or FedF protein. In this work, we show that anti-FedF antibodies, unlike anti-FedE serum, were able to inhibit E. coli adhesion to porcine enterocytes.

Autotransporter Adhesins in Escherichia coli Pathogenesis

PROTEOMICS, 2017
AbstractMost bacteria produce adhesion molecules to facilitate the interaction with host cells and establish successful infections. An important group of bacterial adhesins belong to the autotransporter (AT) superfamily, the largest group of secreted and outer membrane proteins in Gram‐negative bacteria.

Pathogenic Potential to Humans of Bovine Escherichia coli O26, Scotland [PDF]

, 2012
Escherichia coli O26 and O157 have similar overall prevalences in cattle in Scotland, but in humans, Shiga toxin–producing E. coli O26 infections are fewer and clinically less severe than E. coli O157 infections.

Genotypic characterization of virulence factors in Escherichia coli strains from patients with cystitis Caracterização genotípica dos fatores de virulência em amostras de Escherichia coli isoladas de pacientes com cistite

Revista do Instituto de Medicina Tropical de São Paulo, 2008
Adhesins (P-fimbriae, S-fimbriae, type 1 fimbriae and afimbrial adhesin), toxins (α-hemolysin and cytotoxic necrotizing factor type 1), iron acquisition systems (aerobactin) and host defense avoidance mechanisms (capsule or lipopolysaccharide) have ...
