Urinary tract infection is a common problem worldwide. Its clinical characteristics and susceptibility rates of bacteria are important in determining the treatment of choice and its duration. This study assessed the frequency and susceptibility to antimicrobials of uropathogens isolated from community-acquired urinary tract infections in the city of Natal, Rio Grande do Norte State capital, nor...

This study presents a novel approach to aid in diagnosis of urinary tract infections (UTIs). A real-time PCR assay was used to screen for culture-positive urinary specimens and to identify the causative uropathogen. Semi-quantitative breakpoints were used to screen for significant bacteriuria (presence of ≥ 10(5) CFU/ml of uropathogens) or low-level bacteriuria (containing between 10(3) and 10(...

Urinary tract infection is one of the common infections in the Indian community. Distribution and susceptibility of UTI-causing pathogens change according to time and place. This study was conducted to determine the distribution and antimicrobial susceptibility of uropathogens in the Indian community as well as to determine the effect of gender and age on the etiology of bacterial uropathogens....

Biofilm Formation, Antimicrobial Resistance and Biofilm-Related Genes among Uropathogens Isolated from Catheterized Uro-Oncology Patients

Purpose: Urinary tract infection is acommon infectious presentation in the community practice.It is also the most common cause of antimicrobial resistance in the society. The aim of this study was to investigate the frequencyand antimicrobial resistance pattern of the uropathogens isolated from patients with urinary tract infection. Materials and Methods: This study was conducted on the pati...

Antibiotic resistance among uropathogens causing community acquired urinary tract infection (CAUTI) is increasing worldwide. Severity and endemicity persists despite of wide spread availability of drugs. Knowledge of the aetiology and antimicrobial susceptibility patterns of uropathogens is important in order to determine the best empiric treatment option. Extended-spectrum beta-lactamase (ESBL...

Uropathogens other than Escherichia coli occur with greater frequency in patients with risk factors for urinary tract infection (UTI). However, little is known about associations between uropathogen species and host characteristics. Three hundred nineteen urine specimens containing a balanced distribution of uropathogen species were selected from inpatients and outpatients at a university hospi...

The aim of this study was to investigate the antimicrobial effect of lipopeptide biosurfactants from surfactin, iturin and fengycin families, synthesised by the Bacillus subtilis I'1a strain, on uropathogenic bacteria, including the effects on planktonic growth, processes of biofilm formation and dislodging. Antimicrobial activity was tested against 32 uropathogenic strains belonging to 12 diff...

In a randomized crossover study, 16 volunteers (8 men, 8 women) received single oral doses of 320 mg of gemifloxacin and 400 mg of ofloxacin on two separate occasions in the fasting state to assess the urinary excretion and urinary bactericidal titers (UBTs) at intervals for up to 144 h. Ofloxacin showed higher concentrations in urine compared with those of gemifloxacin. The median (range) cumu...
