INTRODUCTION We present a standardized Pseudomonas aeruginosa (PA) infected burn-wound model in mice for evaluating new antimicrobials and therapy strategies for PA infections and demonstrate the effect of the antibiotic imipenem in this model. METHODS A 6%-8% total body surface area, full-thickness, scald-burn wound was induced in anesthetized mice. Two study groups (PA-infected burn) were c...

OBJECTIVE To investigate the protective effect of antibiotherapy in the early phase of acute pancreatitis on cellular injury induced in lungs and liver. BACKGROUND Cellular viability and plasma nitric oxide (NO) levels were assessed to determine the efficacy of highly bactericidal imipenem and quinolones on liver and lung injury. METHODS Imipenem, levofloxacin or saline were administered to...

The prevalence of methicillin-resistant Staphyloccoccus aureus (MRSA) strains has presented a new challenge in antimicrobial medication. Linezolid is a new drug with potent activity on Gram-positive pathogens such as MRSA. The aim of the study was to investigate the in vitro activity of linezolid alone and in combination with imipenem, vancomycin or rifampicin to determine the most active thera...

Meropenem was compared with imipenem/cilastatin for the treatment of serious bacterial infections in a randomized, prospective multicentre study. Both study drugs were given intravenously 1 g every 8 h and no other antimicrobial agents were permitted concomitantly. Of the 204 patients enrolled, the treatment of 177 was evaluable for clinical efficacy and 115 for bacteriological efficacy. In the...

background and objectives: pseudomonas aeruginosa is one of the most important causative agents of nosocomial infections especially in icu and burn units. p. aeruginosa infections are normally difficult to eradicate due to acquired resistance to many antibiotics. recent appearance of carbapenem resistant p. aeruginosa isolates is considered a major healthcare problem. the present study was cond...

Nocardia spp. can lead to local or disseminated infections, especially in immunocompromised patients. Combination therapy of amikacin and imipenem is commonly used to treat severe nocardial infections. We describe a patient with imipenem-resistant Nocardia cyriacigeorgica, which, to our knowledge, has not been previously reported among isolates of this species.

Two children with severe pneumonia, purulent pleural effusions, and abscess formation unresponsive to appropriate antibiotic therapy recovered promptly after the introduction of linezolid and imipenem association. Linezolid is a new antibiotic with high bioavailability and an outstanding safety profile, synergistic with imipenem, which may deserve a place in the armamentarium for severe pneumon...

The MICs of imipenem and piperacillin, alone and in combination, against Pseudomonas aeruginosa were determined in a checkerboard titration microdilution assay. A dramatic, one-way antagonism of imipenem for piperacillin was demonstrated in 28 of the 35 strains examined; antagonism was associated with the induction of a beta-lactamase.

Imipenem distribution was characterized by microdialysis in the peritoneal fluid of rats with experimental pancreatitis. The ratios of peritoneal fluid to blood area under unbound concentration-versus-time curves were close to unity, suggesting that imipenem was not degraded in peritoneal fluid.
