Authors: Bader MS, Loeb M, Leto D, Brooks AA Abstract Urinary tract infections (UTIs) caused by antibiotic- resistant Gram-negative bacteria are a growing concern due to limited treatment options. Knowledge of the common uropathogens in addition to local susceptibility patterns is essential in determining appropriate empiric antibiotic therapy of UTIs. The recommended first-line empiric antibiotic therapy for acute uncomplicated bacterial cystitis in otherwise healthy adult nonpregnant females is a 5-day course of nitrofurantion, a 3-g single dose of fosfomycin tromethamine, or a 5-day course of pevmecillinam. High...

ConclusionIt is concluded that NIT resistance in the studied NIT-RE. coli isolates was mainly mediated by nfsA and nfsB alterations.

AbstractPurposeUrinary tract infections (UTI) are one of the most common reasons for prescribing antibiotics in primary care. In Switzerland, the Swiss Center for Antibiotic Resistances (ANRESIS) provides resistance data by passive surveillance, which overestimates the true resistance rates. The aim of this study was to provide actual data of the antimicrobial resistance patterns in patients with UTI in Swiss primary care.MethodsFrom June 2017 to August 2018, we conducted a cross-sectional study in 163 practices in Switzerland. We determined the resistance patterns of uropathogens in patients with a diagnosis of a lower UT...

ConclusionsThe effectiveness of COL alone in vitro and in vivo suggested that intravenous CMS will be an effective and available therapeutic strategy for UTI due to MDR gram-negative pathogens. In-depth in vitro tests demonstrated that COL combined with DOR could be an attractive option, especially when COL MIC of the pathogen is ≥ 1 μg/ml.

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 ...

Escherichia coli has found to be the predominant uropathogen (50 –90%) in uncomplicated, community acquired urinary tract infection (UTI). Uropathogenic Escherichia coli (UPEC) express a multitude of virulence fac...

ConclusionsPrior use of cephalosporin or BLBLI combination antibiotics increased the risk ratio forESBL-producingE. coli infection. Hypoproteinemia and severe disease are independent risk factors for death in patients withE. coli BSIs. There was no significant difference in the 28  day prognosis of patients with ESBL-producingE. coli and those with non-ESBL-producingE. coli BSIs. These data do not support the conclusion that carbapenems might be more effective than BLBLI antibiotics for treatment of patients with BSIs caused by ESBL-producingE. coli.

Given increasing antimicrobial resistance, we aimed to determine antibiotic susceptibility and presence of resistance genes in uropathogens in primary care, factors associated with resistance to commonly prescribed antibiotics, and effect of treatment on early symptom resolution. We conducted a prospective study of primary care patients with urinary tract infection (UTI) symptoms and culture-confirmed UTI in Singapore from 2015 to 2016. Cohort characteristics and antimicrobial susceptibility of cultured isolates were analyzed. Among Enterobacteriaceae isolates, early symptom resolution (within 3 days) according to antibiot...

ConclusionsWe think that the most appropriate antibiotic to be chosen for the outpatients for empirical treatment in all age groups in our region, is as oral nitrofurantoin and parenteral amikacin. Also the appropriate parenteral antibiotics that should be selected for the empirical treatment of inpatients UTI in all age groups are the TZP, amikacin and carbapenems.
