OBJECTIVES: We quantified the impact of antibiotics prescribed in primary care for urinary tract infections (UTIs) on intestinal colonisation by ciprofloxacin-resistant (CIP-RE) and extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE), while accounting for household clustering. METHODS: Prospective cohort study from January 2011 to August 2013 at primary care sites in Belgium, Poland and Switzerland. We recruited outpatients requiring antibiotics for suspected UTIs or asymptomatic bacteriuria (exposed patients), outpatients not requiring antibiotics (non-exposed patients), and 1-3 household contacts for each patient...

Introduction: Antibiotic treatment of Urinary Tract Infections (UTI) is becoming increasingly difficult due to emergence of multi-drug resistant (ESBLs, AmpC, CRE) uropathogens. Fosfomycin is an old antibiotic that has evoked renewed interest with unique properties of not sharing any structural similarity and lack of cross-resistance with other antimicrobial agents. Our aim is to evaluate in-vitro activity of Fosfomycin against urinary tract Enterobacteriaceae. Material & Methods: The study period was March 2014 to September 2015...

Sparse data exist from sub-Saharan Africa (SSA) on the prevalence of antimicrobial resistance (AMR). A prior review of antimicrobial resistance in SSA from 1990 to 2013 showed a high prevalence of AMR to commonly used antibiotics in this setting. We reviewed the literature published since 2013. Four databases (PubMed, EMBASE, Cochrane, and African Journals Online) were searched for articles between February 2013 and March 2016 with a focus on sterile site infections (bacteremia, urinary tract infections [UTIs], and meningitis)...

BACKGROUND: The use of a ureteral stent can cause a urinary tract infection (UTI), although it reduces urologic complications. UTIs are associated with a higher rate of ureteral stent colonization (USC). The aim of this study was to compare USC in living and deceased donor renal transplant recipients. MATERIAL AND METHODS: We conducted a prospective study of 48 patients who underwent renal transplantation between January and December 2016. The stents were removed aseptically, the inner surface of proximal and distal ends of stents were irrigated with liquid culture medium, and then they were vortexed for bacteriological investigation...

Objectives: To evaluate temporal trends in antimicrobial resistance, over 16 years, in bacteria isolated from dogs and cats with urinary tract infection (UTI) and the clonal lineages of bacteria harbouring critical antimicrobial resistance mechanisms. Methods: Antimicrobial susceptibility testing was conducted for 948 bacteria isolated from dogs and cats with UTI (1999-2014). Resistance mechanisms were detected by PCR, namely ESBL/AmpC in third-generation cephalosporin (3GC)-resistant Escherichia coli and Proteus mirabilis, mecA in methicillin-resistant staphylococci, and aac(6')-Ieaph(2″)-Ia and aph(2″)-1d in high-level gentamicin-resistant (HLGR) enterococci...

The spread of antimicrobial resistance challenges the empiric treatment in urinary tract infections (UTI). Among others, nitrofurantoin is recommended for first line treatment, but acceptance among clinicians is limited due to chronic nitrofurantoin-induced lung toxicity and insufficient coverage of Enterobacteriaceae other than Escherichia coli. Nitroxoline seems to be an alternative to nitrofurantoin due to its favourable safety profile but data on its current in vitro susceptibility are sparse. In this study susceptibility to nitroxoline was tested against 3,012 urinary clinical isolates (including multidrug-resistant bacteria and Candida spp...

Background: Broad-spectrum antibiotics are often used to treat urinary tract infections (UTIs) due to drug-resistant species of Enterobacteriaceae and Enterococcus (e.g., organisms producing extended-spectrum β-lactamase [ESBL] or AmpC β-lactamase, as well as vancomycin-resistant enterococci [VRE]). However, this type of therapy can promote selection of resistant organisms and may necessitate venous access. Fosfomycin is an orally administered, single-dose antibiotic for the treatment of uncomplicated UTI...

Background: Urinary tract infections (UTIs) are one of the most common bacterial infections in women. During pregnancy physiological changes, like frequency, mimic UTI symptoms, and therefore bacteriological cultures are needed to confirm the diagnosis. However, in developing countries antibiotic therapy is commonly initiated without culture confirmation. Methods: We investigated the prevalence of bacteriuria among pregnant women with and without UTI symptoms in Uganda...

This review focuses on the treatment of urinary tract infections (UTI) in children and in particular its recent changes. Areas covered: Acute pyelonephritis, acute cystitis and asymptomatic bacteriuria or asymptomatic infections have to be clearly distinguished. Prompt treatment is required in pyelonephritis and cystitis, but not in asymptomatic bacteriuria or infection, in order to avoid selection of more virulent strains. This concept should be considered even in immunocompromised or bedridden children. In case of pyelonephritis, there should be no delay in beginning the antibiotic treatment in order to decrease the risk of long term complication, such as renal scars...
