...Haedi Thelen; Thomas J. Dilworth; Renée-Claude Mercier Introduction: Community-acquired urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli have limited oral therapeutic options and pose significant clinical challenges. The goal of this study...

... by co-resistance and integron carriage. Results: ESBL producers were more frequent in the LTC applicants than in the employment screening individuals (7.2 vs. 2.0%; p < 0.0001), with 43 Escherichia coli , 18 Klebsiella pneumoniae , 1 Klebsiella oxytoca and 1 Proteus mirabilis being found...

... Enterobacteriaceae isolated in 2008 and 2009 at the University Hospital of Tübingen were analysed retrospectively. Results: Escherichia coli (n = 253) and Klebsiella spp. (n = 46) were the most frequent ESBL-producing species. The ESBL rates among E. coli and Klebsiella spp. increased from 3.8 and 2.1%, respectively...

...Elisabet Guiral; Jordi Bosch; Jordi Vila; Sara M. Soto Background: Bloodstream infections are a significant cause of neonatal morbidity and death. An increase in the incidence of early neonatal sepsis due to Escherichia coli has been reported. The objective was to evaluate the antimicrobial...

... and repeated antibiotic treatment most cancer patients undergo, this question is important. We have examined the possible effects of in vitro long-term antineoplastic exposure on antibiotic resistance. Methods: Using the disc diffusion method, two bacterial strains ( Escherichia coli , ATCC 25922...

... of intoxications, S. aureus represents the most common etiologic agent of purulent infections (e.g. furuncle, carbuncle, abscess, myocarditis, endocarditis, pneumonia, meningitis, bacterial arthritis) [ 4 ]. Escherichia coli is one of the principal causes of infectious diseases in humans. These bacteria...

...Majid Mansouri; Rashid Ramazanzadeh; Parisa Norabadi Cefepime is active against bacteria producing chromosomally and plasmid-mediated extended broad-spectrum β-lactamase enzymes. The aim of this study was to evaluate risk factors for acquisition of cefepime resistance in Escherichia coli strains...

... ] in clinical isolates of Klebsiella pneumoniae and Escherichia coli resistant to extended-spectrum cephalosporin were studied. Results: 5 and 4 of 95 E. coli isolates but 46 (86/187) and 6% (12/187) of K. pneumoniae had qnr and aac(6 ′ )-Ib-cr , respectively, and 8 K. pneumoniae contained both genes .qepA...

...-negative bacterial strains were tested. Morphological changes, such as filamentous development and lysis, occurred at concentrations considerably lower than the MIC values and the presence of R plasmids did not influence the morphological changes compared with those of Escherichia coli NIHJ, which is non-R...

... such as in a foreign body infection. We compared bacteria ( Staphylococcus epidermidis and Escherichia coli )broth suspension MBCs with MBCs of the same bacteria when on a nonnutrient surface in broth the growing and nongrowing phases. Bacteria growing on cotton surfaces were much less susceptible to antibiotic...

...Manoucher Dezfulian; Roger A. Bitar; John G. Bartlett The in vivo activity of ceftriaxone was examined in an experimentally induced subcutaneous infection involving Bacteroides fragilis and Escherichia coli. Mice were challenged with 1 of 10 strains of B. fragilis or E. coli, or a dual combination...

.... The kinetics of filamentation of Escherichia coli were investigated by incubation for various periods up to 18 h, with different subinhibitory concentrations of ceftibuten, from 1/2 to 1/128 of the MIC, corresponding to 0.25-0.003 μg/ml. Normal shapes, short and long filamentation and bacterial ghosts were...

...J.K. Seydel; H. van der Goot; H. Timrnerman In a previous report the dependence of the antimycoplasmal activity of bipyridyl analogues on the presence of Cu + ions has been shown. The inhibitory activity of these compounds has now been studied against Escherichia coli mycobacteria and Candida...

... and the presence of a synergistic effect with gentamicin (GM) against Escherichia coli strains. Antimicrobial activity was evaluated as a delay of the growth curve, using a turbidimetric method. E. coli ATCC 10798 and E. coli SC 12155 were employed as test micro-organisms in nutrient broth, and GM was used...
