Which Orthopaedic Patients Are Infected with Gram-negative Non-fermenting Rods?
Background : 1st and 2nd generation cephalosporins used for perioperative prophylaxis in orthopaedic surgery do not cover non-fermenting Gram-negative rods (NFR). Methods: Epidemiological cohort study of adult patients operated for orthopedic infections between 2004 and 2014 with perioperative cefuroxim or vancomycin prophylaxis. Exclusion of polyneuropathic ischemic foot infections and septic ...
متن کاملCharacterization of the Extended-Spectrum beta-Lactamase Producers among Non-Fermenting Gram-Negative Bacteria Isolated from Burnt Patients
Background & Aims of the Study: Extended-spectrum beta-Lactamases (ESBLs) represent a major group of beta-lactamases which are responsible for resistance to oxyimino-cephalosporins and aztreonam and currently being identified in large numbers throughout the world. The objective of this study was to characterize ESBL producers among non-fermenter gram-negative bacteria isolated from burnt patien...
متن کاملDeoxyribonuclease-indole medium and its use in an identification system for non-lactose fermenting gram-negative rods.
Deoxyribonuclease (DNase) Test Agar with Methyl Green contains 2 per cent tryptose and, when tubed, proved suitable for both DNase and indole tests. DNase activity showed as blanching and indole production as a red ring (upon addition of Ehrlich’s reagent) in the top layer. One hundred sixtyseven strains of fermentative Gram-negative rods were tested for both re actions. With the exception of...
متن کاملPolyclonal bacteremia due to gram-negative rods.
The frequency of, risk factors for, and outcome of polyclonal gram-negative bacteremia are still unknown. We investigated them in a prospective cohort study of patients for whom a blood culture yielded >/=1 species of gram-negative aerobic rod. For each patient, pulsed field gel electrophoresis (PFGE) was performed on 4 colonies of each morphologic type. Episodes of bacteremia were considered p...
متن کاملBeta-lactamase in gram-negative rods: the relationship between penicillinase and R plasmids in gram-negative rods.
Concomitant with the extensive use of antibiotics, the number of multiple antibiotic-resistant strains has been increasing. Since resistance is mainly mediated by R plasmids, we undertook to investigate the characteristics of R plasmid-determined beta-lactamase in 6 Gram-negative rods. The beta-lactamase produced by each organism was classified by its substrate: type P which attacks penicillins...
