BACKGROUND Patients with sickle cell disease have an amplified vulnerability to urinary tract infection, because of abnormally dilute and alkaline urine, which favors bacterial proliferation. This is due to altered blood flow in the renal vasculature, which causes papillary necrosis and loss of urinary concentrating and acidifying ability of the nephrons. Asymptomatic bacteriuria is common, but...

BACKGROUND The efficacy of antimicrobial urinary catheters in hospitalized patients is poorly defined. PURPOSE To assess currently marketed antimicrobial urinary catheters for preventing catheter-associated urinary tract infection (UTI). DATA SOURCES Electronic databases, conference proceedings, bibliographies, trialists, and catheter manufacturers (search dates, 1966 to June 2005). STUDY...

BACKGROUND Staphylococcus aureus is frequently isolated from urine samples obtained from long-term care patients. The significance of staphylococcal bacteriuria is uncertain. We hypothesized that S. aureus is a urinary pathogen and that colonized urine could be a source of future staphylococcal infection. METHODS We performed a cohort study of 102 patients at a long-term care Veterans Affairs...

BACKGROUND Symptomatic and asymptomatic bacteriuria (ASB) is common in pregnant women. Pregnancy enhances the progression from ASB to symptomatic bacteriuria, which if left untreated, could lead to acute pyelonephritis and other adverse outcomes such as prematurity, postpartum, hypertensive disease, anaemia, UTIs and higher foetal mortality rates. AIM To identify the prevalence of ASB, the mo...

Escherichia coli can colonize the urinary bladder without causing a disease response in the host. This asymptomatic bacteriuria (ABU) can protect against recurrent symptomatic urinary tract infection by virulent bacteria. Here, we report the whole-genome sequences of nine E. coli ABU isolates from diabetic patients.

OBJECTIVES AND METHODS The literature on prevention and therapy of urinary tract infection (UTI) in patients with spinal cord injury (SCI) was reviewed using 3 levels of evidence. RESULTS Antibiotic therapy is only indicated in symptomatic bacteriuria or in symptomatic exacerbations of chronic UTI. During the acute phase of a SCI, UTI's are more prevalent and bacteria are different and more r...

Urinary tract infection is mainly a disease of the females, due to the anatomical structure of the female urethra (Shruthi et al., 2012; Lavanya et al., 2002). There are 2 types of urinary tract infection (UTI). They are asymptomatic and symptomatic urinary tract infection (Sujatha et al., 2004; Jeyaseelan et al., 2013; Annie et al., 2014). The definition of asymptomatic bacteriuria is the occu...

Guidelines for the diagnosis, prevention, and management of persons with catheter-associated urinary tract infection (CA-UTI), both symptomatic and asymptomatic, were prepared by an Expert Panel of the Infectious Diseases Society of America. The evidence-based guidelines encompass diagnostic criteria, strategies to reduce the risk of CA-UTIs, strategies that have not been found to reduce the in...

During a 3-year study period, 32,741 urine samples were analyzed for the presence of members of the Staphylococcus sciuri group (S. sciuri, S. lentus, and S. vitulinus), and 13 isolates were identified. They presented 0.79% of the total number of coagulase-negative staphylococci isolated. One case of symptomatic urinary tract infection and five possible cases of asymptomatic bacteriuria caused ...

Urinary tract infections are common complications of pregnancy; upper tract infections in particular may lead to significant morbidity for both the mother and fetus. Bacteriuria is a significant risk factor for developing pyelonephritis in pregnant women. Therefore, proper screening and treatment of bacteriuria during pregnancy is necessary to prevent complications. All women should be screened...
