Eva Raphael, Lee W Riley
Background: Drug-resistance genes found in human bacterial pathogens are increasingly recognized in saprophytic Gram-negative bacteria (GNB) from environmental sources. The clinical implication of such environmental GNBs is unknown. Objectives: We conducted a systematic review to determine how often such saprophytic GNBs cause human infections. Methods: We queried PubMed for articles published in English, Spanish, and French between January 2006 and July 2014 for 20 common environmental saprophytic GNB species, using search terms "infections," "human infections," "hospital infection...

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...
