OBJECTIVES: We analyzed bacterial strains isolated from urine samples of patients with urinary tract infections (UTI) at Okayama University Hospital over a 30-year period to characterize trends in species and antimicrobial susceptibilities. METHODS: Clinical isolates were collected from in- and out-patients with pyuria and bacteriuria who were treated between 1984 and 2014 (one episode per patient and plural isolates were counted in polymicrobial infection). We examined these isolates to identify pathogens and tested for antimicrobial susceptibility...

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...

REVIEW
Marina de Cueto
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...

For a rational diagnostic work-up of urinary tract infections (UTI), a detailed history and a standardised examination of smear material, prostatic fluid and urine are essential. Examination of the urine is simple, with test strips, microscopic examination of the sediment and determination of the bacterial count by the dipstick procedure having proved their worth in practice. Isolation and identification of pathogens and the preparation of an antibiogram require special knowledge of microbiological techniques...

The spectra of bacterial organisms of urinary tract infections (UTI) in patients with and without abnormalities in the urinary tract (complicated and uncomplicated UTIs) are compared. Data from the United Kingdom and the Federal Republic of Germany are included. In addition, the susceptibility of the pathogens to antibiotics (for oral or parenteral application) in both countries are compared. In conclusion, rational antibiotic therapy of complicated UTIs should strictly follow the antibiogram of the causative organism...
