Rapid emergence of extensively drug-resistant Shigella sonnei in France

Nature Communications, 2023
There have been increasing reports of extensively drug-resistant (XDR) Shigella sonnei infections in recent years. In this laboratory surveillance study from France, the authors document the rise of XDR isolates from 2005 to 2021 and perform whole genome

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

Toxins, 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).

Population structure analysis and laboratory monitoring of Shigella by core-genome multilocus sequence typing

Nature Communications, 2022
Lab-based surveillance of Shigella has traditionally been based on serotyping but increasing availability of whole genome sequencing could enable higher resolution typing.

High Risk Clone: A Proposal of Criteria Adapted to the One Health Context with Application to Enterotoxigenic Escherichia coli in the Pig Population

Antibiotics, 2021
The definition of a high risk clone for antibiotic resistance dissemination was initially established for human medicine. We propose a revised definition of a high risk clone adapted to the One Health context.

Occurrence and Genomic Characterization of Clone ST1193 Clonotype 14-64 in Uncomplicated Urinary Tract Infections Caused by Escherichia coli in Spain

Microbiology Spectrum, 2022
We conducted a prospective, multicenter, specific pilot study on uncomplicated urinary tract infections (uUTI). One-hundred non-duplicated uropathogenic Escherichia coli (UPEC) from uUTI occurred in 2020 in women attending 15 primary care centers of a ...

Radiosensitivity in Escherichia coli [PDF]

Journal of General Microbiology, 1963
SUMMARY: A radiosensitive mutant of Escherichia coli strain K12, W3747 was found to be similar to E. coli strains b and s with respect to survival following ultraviolet irradiation, plating-medium recovery, ability to ‘reactivate’ irradiated T1 phage, and in its cross-resistance pattern with radiomimetic chemicals.

Comparison of Two Shiga Toxin-producing Escherichia coli (STEC) Isolation Protocols in Raw Cow’s Milk Cheese Enrichment Broths: Direct STEC Isolation Versus Techniques Based on Immuno-concentration

Journal of Food Protection, 2023
The presence of Shiga toxin-producing Escherichia coli (STEC) in dairy products made with raw milk is a major concern for food safety authorities and industries. Two approaches have been proposed to isolate STEC from food.

Genomic Characterization of Escherichia coli Isolates Belonging to a New Hybrid aEPEC/ExPEC Pathotype O153:H10-A-ST10 eae-beta1 Occurred in Meat, Poultry, Wildlife and Human Diarrheagenic Samples

Antibiotics, 2020
Different surveillance studies (2005–2015) in northwest Spain revealed the presence of eae-positive isolates of Escherichia coli O153:H10 in meat for human consumption, poultry farm, wildlife and human diarrheagenic samples.

Autolysis of Escherichia coli [PDF]

Journal of Bacteriology, 1980
Autolysis of unwashed exponential-phase Escherichia coli cells was efficiently promoted by first submitting them to a quick downshock with distilled water before an upshock with 0.5 M sodium acetate, pH 6.5. The association of these two osmotic shocks had a remarkable synergistic effect and led to significant decreases in turbidity and viability ...

High Prevalence of ST131 Subclades C2-H30Rx and C1-M27 Among Extended-Spectrum β-Lactamase-Producing Escherichia coli Causing Human Extraintestinal Infections in Patients From Two Hospitals of Spain and France During 2015

Frontiers in Cellular and Infection Microbiology, 2020
The present study was carried out to evaluate the prevalence of sequence type 131 (ST131) among 188 extended-spectrum β-lactamase-producing Escherichia coli (ESBL-EC) collected in 2015 in Lucus Augusti University hospital (Lugo, Spain) and AP-HP Beaujon ...
