OBJECTIVETo evaluate risk factors for and molecular characteristics of community-onset extended-spectrum cephalosporin-resistant (ESC-R) Enterobacteriaceae (EB) urinary tract infections (UTIs) in a US health system.DESIGNCase-control study.PARTICIPANTSAll patients presenting to the emergency department or outpatient practices with EB UTIs from December 21, 2010, through April 22, 2013, were included. Case patients had ESC-R EB UTIs. Control patients had ESC-susceptible EB UTIs and were matched 1:1 on study year.METHODSRisk factors for ESC-R EB UTI were assessed using multivariable conditional logistic regression. A subset of case isolates was evaluated for extended-spectrum beta-lactamases.RESULTSA total of 302 patients with community-onset EB UTI were included, of which 151 were cases. On multivariable analysis, risk factors for ESC-R EB UTI included trimethoprim-sulfamethoxazole use in the prior 6 months (odds ratio, 2.40 [95% CI, 1.22–4.70];P=.01), older age (1.03 [1.01–1.04];P<.001), diabetes (2.91 [1.32–6.41];P=.008), and presentation to the emergency department ( 2.42 [1.31–4.46];P=.005). The prevalence of extended-spectrum beta-lactamases among 120 case isolates was 52% CTX-M, 29% TEM, 20% OXA, and 13% SHV. The prevalence of AmpC was 25%. Pulsed-field gel electrophoresis of the CTX-MEscherichia coliisolates showed no distinct clusters.CONCLUSIONSUse of trimethoprim-sulfamethoxazole, older age, diabetes, and presentation to the emergency department were associated with community-onset ESC-R EB UTI. There was a high prevalence of CTX-M among our community isolates. Further studies are needed to determine strategies to limit emergence of these organisms in the community.Infect Control Hosp Epidemiol2016;1433–1439

Abstract Background: Gram-negative enterobacteria are the most common cause of urinary tract infections. Cedecea is a new separate genus in the family enterobacteriaceae, and it is a very rare pathogen that was primarily found in the respiratory tract. Cedecea lapagei is a very rare pathogen of urinary tract infections. To the best of our knowledge, this is the first case report in the world reported in English literature. Case presentation: A 55 years old man with chronic renal failure, poorly controlled diabetes mellitus, and hypertension presented with acute exacerbations of renal failure and irritative voiding symptoms. After stabilization and empirical antibiotic therapy with Ceftriaxone, the patient’s condition was not improved and deteriorated progressively. After the request of urine culture, the culture was isolated, an extremely rare uropathogen recently recognized by the Centers for Disease Control and Prevention (CDC); the Cedecea lapagei. Cedecea lapagei identification had been done using Eosin methylene blue agar (EMB). Gram-negative lipase positive bacteria with bacillus in shape, motile in nature that is non-spore-forming, and non-encapsulated enterobacteria with the final result of >100,000 colony-forming units per ml of Cedecea lapagei were isolated. Mueller-Hinton agar had been used to perform antimicrobial sensitivity and resistance. The pathogen was extensively resistant to the extended-spectrum beta-lactamases antibiotics and extended-spectrum beta-lactam inhibitors while carbapenems, fluoroquinolones, aminoglycosides, and Trimethoprim-sulfamethoxazole showed a higher sensitivity rate. Conclusion: The treatment of Cedecea lapagei infections represents a challenging issue due to its multi-drug resistant and extensive drug resistance patterns to a variety of antimicrobial classes, such as extended-spectrum beta-lactamases, cephalosporins, and beta-lactam inhibitors. Antimicrobial treatment should be aligned with the culture findings once available.

AbstractObjectiveTo identify patterns of resistance against quinolones in various uropathogens in urinary tract infections in the population of the Toluca valley, MexicoIntroductionQuinolones are antibiotics with a spectrum of activity for both gram-positives and gram-negatives and are antibiotics used for the empirical treatment of urinary tract infections. Recently, a high index of resistance to quinolones has been reported due to different mechanisms on the part of bacteria, however the one that has taken the greatest importance is the presence of extended spectrum beta-lactamasesMethods155 samples were collected from patients with suspected urinary tract infection without exclusion criteria such as age or gender. Automated equipment was used for the identification of the etiological agent and sensitivity tests to quinolones.ResultsThe results positives were divided to evaluate which of the two antibiotics studied had greater resistance. For ciprofloxacin there are 27 resistant strains 37%, 1 strain with intermediate resistance 1% and 45 susceptible strains 62%. For levofloxacin 26 strains are resistant 36%, 41 strains are sensitive 56% and 6 strains show intermediate sensitivity 8%.ConclusionDifferent microorganisms, both gram-positive and gram-negative, were isolated and it can be observed that gram-negative strains are the ones with the greatest resistance against quinolones, mainly Escherichia coli, which produces extended-spectrum beta-lactamases, in the case of gram-positive resistance patterns are variable with a tendency towards sensitivity.
