Uropathogenic  (UPEC) is the most common cause of urinary tract infection (UTI). This disease disproportionately affects women and frequently develops into recurrent UTI (rUTI) in postmenopausal women. Here, we report the complete genome sequences of seven UPEC isolates obtained from the urine of postmenopausal women with rUTI.

Complete Genome Sequences of Seven Uropathogenic Escherichia coli Strains Isolated from Postmenopausal Women with Recurrent Urinary Tract Infection.

Recurrent urinary tract infection (rUTI) poses a major health issue, especially among postmenopausal women. We report complete genome sequences of three  strains isolated from the urine of postmenopausal women with rUTI.  is a recently identified  species with clinical and virulence characteristics distinct from those of .

Complete Genome Sequences of Three Uropathogenic Klebsiella quasipneumoniae Strains Isolated from Postmenopausal Women with Recurrent Urinary Tract Infection.

Urinary tract infection (UTI) is one of the most common adult bacterial infections and exhibits high recurrence rates, especially in postmenopausal women. Studies in mouse models suggest that cyclooxygenase-2 (COX-2)-mediated inflammation sensitizes the bladder to recurrent UTI (rUTI). However, COX-2-mediated inflammation has not been robustly studied in human rUTI. We used human cohorts to assess urothelial COX-2 production and evaluate its product, PGE, as a biomarker for rUTI in postmenopausal women. We found that the percentage of COX-2-positive cells was elevated in inflamed versus uninflamed bladder regions. We analyzed the performance of urinary PGE as a biomarker for rUTI in a controlled cohort of 92 postmenopausal women and PGE consistently outperformed all other tested clinical variables as a predictor of rUTI status. Furthermore, time-to-relapse analysis indicated that the risk of rUTI relapse was 3.6 times higher in women with above median urinary PGE levels than with below median levels. Taken together, these data suggest that urinary PGE may be a clinically useful diagnostic and prognostic biomarker for rUTI in postmenopausal women.
