Urinary tract infection (UTI) is one of the most common bacterial infections in pediatrics. Delay in diagnosis and treatment can cause significant morbidity. The physicians knowledge regarding the symptoms, microorganisms that caused UTI, and effective antibiotics in a geographical area can help them to select the appropriate antibiotics. This study was performed to determine the prevalence of bacteria that cause UTI and their susceptibility to common antibiotics as well as the common symptoms and associated factors in children of Shiraz, Southern Iran...

Despite the known clonal distribution of antibiotic resistance in many bacteria, empiric (pre-culture) antibiotic selection still relies heavily on species-level cumulative antibiograms, resulting in overuse of broad-spectrum agents and excessive antibiotic/pathogen mismatch. Urinary tract infections (UTIs), which account for a large share of antibiotic use, are caused predominantly by Escherichia coli, a highly clonal pathogen. In an observational clinical cohort study of urgent care patients with suspected UTI, we assessed the potential for E...

Escherichia coli (E. coli) strains are the major cause of urinary tract infections (UTI) and belong to the large group of extra-intestinal pathogenic E. coli. The purposes of this study were to determine the antibiotic resistance profile, virulence genes and phylogenetic background of E. coli isolates from UTI cases. A total of 137 E. coli isolates were obtained from UTI samples. The antimicrobial susceptibility of confirmed isolates was determined by disk diffusion method against eight antibiotics. The isolates were examined to determine the presence and prevalence of selected virulence genes including iucD, sfa/focDE, papEF and hly...

BACKGROUND: Urinary tract infections (UTI) are common in clinical practice and empirical treatment is largely employed due to predictability of pathogens. However, variations in antibiotic sensitivity patterns do occur, and documentation is needed to inform local empirical therapy. The current edition of the Uganda Clinical Guidelines recommends amoxicillin or cotrimoxazole as choice drugs for empirical treatment of community-acquired UTI. From our clinical observations, we suspected that this recommendation was not effective in our setting...

Escherichia coli cause the majority of urinary tract infections (UTIs). Virulence plays an important role in the initial stages of interaction with the host, facilitating colonization of the urinary tract tissue. The purpose of this study was to assess whether there is a relationship between virulence and antibiotic resistance in the persistence of uropathogenic E. coli strains. This study included five patients with UTI between 2001 and 2009. The antibiotic resistance phenotype of 29 E. coli isolates was determined by the disk diffusion method...

Definitive diagnosis of urinary tract infection (UTI) is performed through quantitative urine culture. Traditionally the presence of 100,000 or more bacteria/ml in urine has been considered to represent significant bacteriuria, indicating UTI. However, this criterion is only applicable to certain population groups and cannot currently be considered an absolute criterion. The "real" presence of any number of bacteria in urine can represent a UTI when there are specific symptoms and pyuria. In the last few years various automatic systems have been introduced onto the market which, by adapting classical diagnostic techniques, allow the presence of a UTI to be rapidly ruled out, although their clinical utility is controversial...
