The pst gene cluster encodes the phosphate specific transport system (Pst). Inactivation of the Pst system constitutively activates the two-component regulatory system PhoBR and attenuates virulence of pathogenic bacteria. In uropathogenic E. coli strain CFT073, attenuation by inactivation of pst is predominantly attributed to the decreased expression of type 1 fimbriae. However, the molecular mechanisms connecting the Pst system and type 1 fimbriae are unknown. To address this, a transposon library was constructed in the pst mutant, and clones were tested for a regain in type 1 fimbriae production...

BACKGROUND: Prevalence of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) has risen in kidney transplant (KT) patients, with no long-term data so far on graft function or survival. METHODS: KT patients with ESBL-E-positive urine culture were retrospectively analyzed regarding initial adequate antimicrobial therapy, recurrent infection, transplant function, and survival compared with an ESBL-E-negative KT control cohort. RESULTS: ESBL-E-positive KT patients (n = 93) were older (55...

The identification of the host defence peptides as target effectors in the innate defence of the uro-genital tract creates new translational possibilities for immunomodulatory therapies, specifically vaginal therapies to treat women suffering from rUTI, particularly those carrying the TLR5_C1174T SNP. Urinary tract infections (UTIs) are a microbial disease reported worldwide. Women are particularly susceptible with many suffering debilitating recurrent (r) infections. Treatment is by antibiotics, but such therapy is linked to antibiotic resistance and re-infection...

BACKGROUND: Women with acute uncomplicated urine infection are usually treated with antibiotics. One trial has demonstrated that delayed antibiotic treatment offered without symptom relief results in a modest reduction in antibiotic use. There is some evidence that ibuprofen provides symptom relief and reduces antibiotic use. Uva-ursi, a herbal product, has a traditional use for urinary infection symptom relief. We set out to test: in adult women with suspected UTI who accept the delayed prescription strategy: Do NSAIDs or uva-ursi (a herbal product) provide relief from urinary symptoms and reduce antibiotic use...

OBJECTIVE: To assess urinary symptoms associated with urinary tract infection (UTI) in a urogynecologic population of women. METHODS: In this cohort study, we enrolled 150 urogynecologic patients who completed the validated UTI Symptom Assessment questionnaire and contributed transurethral catheterized urine samples. The primary measure (UTI diagnosis) was defined in three ways. Self-report (a nonculture-based UTI diagnosis) was defined by a yes or no response to the query "Do you think you have a UTI?" Two culture-based UTI diagnoses also were analyzed: standard urine culture (10 colony-forming units [CFU]/mL or greater) and enhanced quantitative urine culture (10 CFU/mL or greater) of any uropathogen...

BACKGROUND: Neuropathic or neurogenic bladder describes a process of dysfunctional voiding as the result of injury in the brain, spinal cord or nerves innervating the bladder. People with neuropathic bladder, such as from spinal cord injury (SCI), are at significant risk of morbidity from urinary tract infections (UTI). Effective methods to prevent UTI in people with SCI have been sought for many years. Probiotics (micro-organisms that exert beneficial health effects in the host) have been recommended for bacterial interference of the urological tract to reduce colonisation by uropathogen and to manage the dual problems of infection and antibiotic resistance...

We present a new preclinical model to study treatment, resolution, and sequelae of severe ascending pyelonephritis. Urinary tract infection (UTI), primarily caused by uropathogenic Escherichia coli (UPEC), is a common disease in children. Severe pyelonephritis is the primary cause of acquired renal scarring in childhood, which may eventually lead to hypertension and chronic kidney disease in a small but important fraction of patients. Preclinical modeling of UTI utilizes almost exclusively females, which (in most mouse strains) exhibit inherent resistance to severe ascending kidney infection; consequently, no existing preclinical model has assessed the consequences of recovery from pyelonephritis following antibiotic treatment...
