Comparative genomic analysis of uropathogenic strains from women with recurrent urinary tract infection.

Introduction: Recurrent urinary tract infections (RUTIs) caused by uropathogenic are costly public health problems impacting patients' quality of life.

Aim: In this work, a comparative genomics analysis of three clinical RUTI strains isolated from bladder biopsy specimens was performed.

Materials And Methods: One hundred seventy-two whole genomes of urinary tract strains were selected from the NCBI database.

Features of urinary Escherichia coli isolated from children with complicated and uncomplicated urinary tract infections in Mexico.

The Hospital Infantil de México Federico Gómez (HIMFG) is a tertiary care hospital in Mexico City where Escherichia coli is frequently isolated from the urine samples of pediatric patients with urinary tract infections. A collection of 178 urinary Escherichia coli (UEc) isolates associated with complicated and uncomplicated urinary tract infections were evaluated in this study. The patterns of resistance to 9 antibiotic classes showed that 60.

Functional interaction and structural characteristics of unique components of Helicobacter pylori T4SS.

The Helicobacter pylori infection of the human gastric mucosa causes chronic active gastritis and peptic ulcers and is associated with the development of gastric cancer. Epidemiological studies show that these gastric diseases are related to virulent H. pylori strains that harbor the cytotoxin-associated gene pathogenicity island (cag PAI).

[The PQQ-dehydrogenases. A novel example of bacterial quinoproteins].

The word "quinoprotein" describes four groups of different enzymes which have cofactors containing o-quinones. Pyrrolo-quinoline quinone (PQQ) is not covalently attached. PQQ is the cofactor of several quinoprotein bacterial dehydrogenases including glucose dehydrogenase (G-DH), alcohol dehydrogenase (A-DH) and aldehyde dehydrogenase (AL-DH).
