Ampicillin-sulbactam, ticarcillin-clavulanate, cefoxitin, cefotetan, and ceftizoxime are promoted for the treatment of mixed aerobic-anaerobic bacterial infections. Their activities have been compared in vitro but not in vivo. In order to assess the in vivo activities of these agents in serum and interstitial fluid, we administered single, intravenous doses of these antimicrobial agents to heal...

The activities of ampicillin-sulbactam and amoxicillin-clavulanate were studied with 100 selected clinical Escherichia coli isolates with different beta-lactam susceptibility phenotypes by standard agar dilution and disk diffusion techniques and with a commercial microdilution system (PASCO). A fixed ratio (2:1) and a fixed concentration (clavulanate, 2 and 4 micrograms/ml; sulbactam, 8 microgr...

A phenotypic and genotypic analysis of Acinetobacter baumannii was conducted from 2003 to 2008 in Detroit, MI. The incidence of A. baumannii increased from 1.7 to 3.7/1,000 patient days during the study period. Susceptibility to ampicillin-sulbactam and imipenem decreased from approximately 90% to approximately 40%. Genotyping revealed polyclonality, suggesting either emergence of multiple resi...

aim : the present study aimed to compare the eradication rate of h. pylori by traditional amoxicillin, metronidazole, bismuth, and omeprazole regimen, with a new one using clarithromycin, omeprazole and ampicillin/sulbactam (penbactam). background : due to the appearance of amoxicillin-resistant h. pylori strains all over the world, the decreased efficacy of conventional amoxicillin-containing ...

OBJECTIVE To evaluate the clinical usefulness of piperacillin (4 g/day) therapy for community-acquired pneumonia compared to sulbactam/ampicillin (6 g/day). METHODS A randomized prospective clinical study was conducted in patients with mild to severe community-acquired bacterial pneumonia. RESULTS The overall clinical efficiency of piperacillin therapy (4 g/day) in these patients (41/53=77....

BACKGROUND There has been an increase in worldwide infections caused by carbapenem-resistant Acinetobacter. This poses a therapeutic challenge as few treatment options are available. OBJECTIVES The aim of this study was to evaluate the efficacy and safety of polymyxins and ampicillin/sulbactam for treating infections caused by carbapenem-resistant Acinetobacter spp. and to evaluate prognostic...

conclusions all the staphylococcus aureus strains and enterococcus faecium strains were sensitive to members of the oxazolidinone class of linezolid drug. development of multi drug resistance by gram positive bacteria constitutes a very serious challenge for medical practice. despite these rising rates, it is impossible to distinguish where they have originated from and special attention has th...
