O55 Polysaccharides Are Good Antigen Targets for the Formulation of Vaccines against O55 STEC and Capsulated aEPEC Strains

open access: yesPathogens, 2022
The serogroup O55 of E. coli is composed of strains whose mechanisms of virulence are different from each other. Since the O55 polysaccharides are present in all E.

Derivation of Escherichia coli O157:H7 from Its O55:H7 Precursor [PDF]

open access: yesPLoS ONE, 2010
There are 29 E. coli genome sequences available, mostly related to studies of species diversity or mode of pathogenicity, including two genomes of the well-known O157:H7 clone. However, there have been no genome studies of closely related clones aimed at

Evolutionary Context of Non-Sorbitol-Fermenting Shiga Toxin-Producing Escherichia coli O55:H7. [PDF]

open access: yesEmerging Infectious Diseases, 2017
In July 2014, an outbreak of Shiga toxin–producing Escherichia coli (STEC) O55:H7 in England involved 31 patients, 13 (42%) of whom had hemolytic uremic syndrome.

Comparative Genomics of Escherichia coli Serotype O55:H7 Using Complete Closed Genomes

open access: yesMicroorganisms, 2022
Escherichia coli O55:H7 is a human foodborne pathogen and is recognized as the progenitor strain of E. coli O157:H7. While this strain is important from a food safety and genomic evolution standpoint, much of the genomic diversity of E.

Tissue Tropism of Enteropathogenic Escherichia coli Strains Belonging to the O55 Serogroup [PDF]

open access: yesInfection and Immunity, 2002
Four enteropathogenic Escherichia coli (EPEC) strains belonging to the O55 serogroup (G21 and G30 [both O55:H6], G35 [O55:H−], and G58 [O55:H7]) were tested for their tissue tropism by using human intestinal in vitro organ culture.

Clonal structure and virulence factors in strains of Escherichia coli of the classic serogroup O55 [PDF]

open access: yesInfection and Immunity, 1996
Virulence properties and genetic variation as determined by multilocus enzyme electrophoresis were studied in 70 strains of Escherichia coli O55, a common serogroup of enteropathogenic E.

Aggregation behavior and size of lipopolysaccharide from Escherichia coli O55:B5

open access: yesColloids and Surfaces B: Biointerfaces, 2006
Dynamic light scattering, steady-state fluorescence, NMR diffusometry and cryo-TEM have been used to gain more insight into the aggregation behaviour of LPS from Escherichia coli O55:B5.

Escherichia coli mediated resistance of Entamoeba histolytica to oxidative stress is triggered by oxaloacetate. [PDF]

open access: yesPLoS Pathogens, 2018
Amebiasis, a global intestinal parasitic disease, is due to Entamoeba histolytica. This parasite, which feeds on bacteria in the large intestine of its human host, can trigger a strong inflammatory response upon invasion of the colonic mucosa.

Emergence of New ST301 Shiga Toxin-Producing Escherichia coli Clones Harboring Extra-Intestinal Virulence Traits in Europe

open access: yesToxins, 2021
O80:H2 enterohemorrhagic Escherichia coli (EHEC) of sequence type ST301 is one of the main serotypes causing European hemolytic and uremic syndrome, but also invasive infections, due to extra-intestinal virulence factors (VFs).
