... 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...

... by enterobacteriaceae and nonfermenters and to study the resistance of polymer surface-grown gram-negative rods against antibiotics. Using a modification of the semiquantitative method for culturing vascular cannulas on solid media described by Maki et al., we studied the adherence of various gram-negative rods to 1-cm...

...Joram Keness; Zwi Efrati; Raul Raz Cefuroxime and cefonicid, two common representatives of the second-generation cephalosporins, were compared for their spectrum of activity against 1,000 isolates of gram-negative Enterobacteriaceae. Cefuroxime had an overall advantage of 6.3% over cefonicid. Upon...

... of Enterobacteriaceae. 91 % were susceptible to cefotaxime, 93.5% were susceptible to gentamicin, 89.5% were susceptible to amikacin and 68% were susceptible to tobramycin. There were 95 strains which could be evaluated for synergistic killing by the antimicrobial combinations. Synergism was shown against 78...

...J.M. Wilson; P.A. Hunter Cefotaxime has extremely low MIC values in comparison with amoxycillin against Enterobacteriaceae , but studies of antibacterial activity using turbidimetric and viable count methods show no advantage for cefotaxime. Superior rates of killing have been demonstrated...

...Samuel L. Rosenthal; Lawrence F. Freundlich; M.A.H. Quraishi A collection of gentamicin-resistant Enterobacteriaceae strains was significantly more resistant to cefamandole than a species-matched collection of gentamicin-sensitive organisms. Cefamandole and gentamicin resistance could...

... of Enterobacteriaceae, Staphylococcus and Streptococcus were quite similar. Gentamicin, however, was approximately fourfold more active against strains of S. marcescens. Amikacin was the most effective antibiotic against strains of fermenting and nonfermenting bacilli resistant to at least one aminoglycoside. Many...
