Decreased antibiotic susceptibility of Enterobacteriaceae causing community-acquired urinary tract infections in French Amazonia.

CONCLUSIONS: Antibiotic susceptibility in UTI is lower than reported in metropolitan France without evidence for an excessive consumption of antibiotics. PMID: 30385068 [PubMed - as supplied by publisher]

Here, we investigated omptin protease ‐mediated antimicrobial resistance among uropathogenicEscherichia coli clinical isolates. We found that clinical isolates with the highest omptin protease activity encode multiple omptin proteases, showing different substrate specificities. Our data suggest that the presence of multiple omptin family proteases in a single clinical isolate may provide a fitness advantage by expanding the range of natural antimicrobial peptides cleaved during urogenital tract colonization. AbstractBacterial colonization of the urogenital tract is limited by innate defenses, including the production of ...

Abstract Diabetes mellitus (DM) is a common disease in Oman as in rest of Gulf Cooperation Council where metabolic syndrome is of high prevalence. DM is a foremost risk factor for urinary tract infections (UTIs). It is also linked to more complicated infections such as emphysematous pyelonephritis (EPN), emphysematous pyelitis (EP), renal/perirenal abscess, emphysematous cystitis, xanthogranulomatous pyelonephritis, and renal papillary necrosis. The diagnosis of these cases is frequently delayed because the clinical manifestations are generic and not different from the typical triad of upper UTI, which include fev...

Urinary tract infections, including cystitis and pyelonephritis, are the most common bacterial infection primary care clinicians encounter in office practice. Dysuria and frequency in the absence of vaginal discharge and vaginal irritation are highly predictive of cystitis. Urine culture is recommended for the diagnosis and management of pyelonephritis, recurrent urinary tract infection, and complicated urinary tract infections. Antibiotics targeted toward Escherichia coli, Proteus, Klebsiella, and Staphylococcus saprophyticus are the recommended treatment. The duration of treatment varies by specific drug and type of infe...

In this study, we sought to establish a new, carefully optimized method to extract and purify non-denatured, native FliC from the reference UPEC strain CFT073 to be suitable for immune assays. To achieve purification of FliC to homogeneity, we used a mutant CFT073 strain containing deletions in four major chaperone-usher fimbriae operons (type 1, F1C and two P fimbrial gene clusters; CFT073Δ4). A sequential flagella extraction method based on mechanical shearing, ultracentrifugation, size exclusion chromatography, protein concentration and endotoxin removal was applied to CFT073Δ4. Protein purity and integrity ...

CONCLUSION: Currently, a second or third generation cephalosporin and amoxicillin-clavulanate are drugs of choice in the treatment of acute uncomplicated UTI. Parenteral antibiotic therapy is recommended for infants ≤ 2 months, and any child who is toxic-looking, hemodynamically unstable, immunocompromised, unable to tolerate oral medication, or not responding to oral medication. A combination of intravenous ampicillin and intravenous/intramuscular gentamycin or a third-generation cephalosporin can be used in those situations. Routine antimicrobial prophylaxis is rarely justified, but continuous antimicrobial prophylaxi...

The objective of this study was to investigate whether a single aminoglycoside dose adequately treated UTI.Methods: A systematic search of PubMed/MEDLINE and Google Scholar databases was performed through September 2018 for English-language original research articles assessing the efficacy of one-time parenteral aminoglycoside as UTI monotherapy.Results: Of 252 potentially relevant studies, 13 met inclusion criteria, representing 13,804 patients. Patient age ranged from 2 weeks to>70 years; both inpatient and outpatient settings were represented. Cystitis was more common than pyelonephritis and more females were represe...

Authors: Kalinderi K, Delkos D, Kalinderis M, Athanasiadis A, Kalogiannidis I Abstract Urinary tract infections (UTIs) are the most common bacterial infection in pregnancy, increasing the risk of maternal and neonatal morbidity and mortality. Urinary tract infections may present as asymptomatic bacteriuria, acute cystitis or pyelonephritis. Escherichia coli is the most common pathogen associated with both symptomatic and asymptomatic bacteriuria. If asymptomatic bacteriuria is untreated, up to 30% of mothers develop acute pyelonephritis, with an increased risk of multiple maternal and neonatal complications, such a...

Abstract Rapid, inexpensive and sensitive detection of uropathogenic Escherichia coli (UPEC), a common cause of ascending urinary tract infections (UTIs) including cystitis and pyelonephritis, is critical given the increasing number of cases and its recurrence worldwide. In this paper, we present a label-free nanoplasmonic sensing platform, built with off-the-shelf optical and electronic components, which can detect intact UPEC at concentrations lower than the physiological limit for UTI diagnosis, in real time. The sensing platform consists of a red LED light source, lens assembly, CMOS detector, Raspberry Pi int...
