Functional and genetic adaptations contributing to Enterococcus faecalis persistence in the female urinary tract

This study identifies genetic adaptations in Enterococcus faecalis strains isolated from the urinary tract of postmenopausal women that may contribute to their persistence in the urinary tract.

Nitrogen-limitation independent control of glnA (glutamine synthetase) expression in Escherichia coli by urea, several amino acids, and post-transcriptional regulation.

This paper shows that glnA expression in uropathogenic E. coli grown in urine is not due to nitrogen limitation but is induced by urea and urinary amino acids through post-transcriptional control.

Urinary Glycosaminoglycans are Associated with Recurrent UTI and Urobiome Ecology in Postmenopausal Women

This study examines urinary glycosaminoglycan (GAG) composition in postmenopausal women and links it to recurrent UTI and urobiome ecology.

Bacterial growth-promoting properties of pooled urine and individual urines from post-menopausal women with or without a urinary tract infection can vary substantially

The paper investigates bacterial growth in urine from post-menopausal women with and without UTIs, finding significant variation in growth rates and suggesting pooled urine may not represent an average.

Conserved FimK truncation coincides with increased expression of type 3 fimbriae and cultured bladder epithelial cell association in Klebsiella quasipneumoniae

This study identifies a conserved FimK truncation in K. quasipneumoniae that increases type 3 fimbriae expression and bladder epithelial cell association compared to K. pneumoniae.

Recurrent urinary tract infection and estrogen shape the taxonomic ecology and functional potential of the postmenopausal urobiome

This study investigates how recurrent UTI and estrogen influence the urobiome's taxonomic and functional features in postmenopausal women using metagenomic and metabolomic analyses.

The Nutrient and Energy Pathway Requirements for Surface Motility of Nonpathogenic and Uropathogenic Escherichia coli

The paper examines the nutrient and pathway requirements for surface motility in nonpathogenic and uropathogenic E. coli strains, finding differences in metabolic dependencies based on appendage type.

FIMBRIAE AND FLAGELLA MEDIATED SURFACE MOTILITY AND THE EFFECT OF GLUCOSE ON NONPATHOGENIC AND UROPATHOGENIC ESCHERICHIA COLI

This study compares surface motility in nonpathogenic and uropathogenic E. coli, showing differences in appendage use and glucose effects on flagella synthesis.
