The clinical outcome in patients treated with ampicillin-sulbactam may not always be predictable by disc susceptibility testing or with the MIC as determined with a constant level (4 micrograms/ml) of the beta-lactamase inhibitor (MIC1). The enzyme activities (EA) and the MICs estimated at a constant ratio of ampicillin to sulbactam of 2:1 (MIC2) for 15 TEM-1 beta-lactamase-producing strains of...

INTRODUCTION Intra-amniotic infection (IAI) and early-onset postpartum endometritis (PPE) require prompt antibiotic treatment and are generally treated by either of two regimens. A complicated multi-agent regimen is most commonly used, despite a lack of clear evidence that it produces better outcomes than a simpler single-agent regimen. OBJECTIVE We compared treatment outcomes between a multi...

A total of 92 isolates of Mycobacterium tuberculosis consisting of equal numbers of sensitive and resistant strains was tested for their susceptibility to sulbactam and ampicillin (in the ratio of 1:2) on Lowenstein-Jensen (LJ) and 7H11 agar media. The geometric mean MIC was 63.97 micrograms/ml for the drug sensitive strains and 65.92 micrograms/ml for the resistant strains, and the overall mea...

Antibiotic-resistant enterococci are being increasingly identified as causal agents of infection. Trovafloxacin is a new fluoronaphthyridone with enhanced activity against gram-positive cocci and variable activity reported against Enterococcus spp. Twenty-one strains of vancomycin-resistant Enterococcus faecium and two strains of Enterococcus faecalis (one vancomycin resistant) were studied at ...

Many studies have elucidated the risk factors associated with peri-operative infection following head and neck cancer surgery (HNS), the implications of infection for total treatment cost, and the clinical benefits of successful antimicrobial prophylaxis. The most appropriate antibiotic use is achieved by focusing on patients with clean, contaminated wounds. Thereafter, the usefulness of an ant...

OBJECTIVE Ampicillin plus sulbactam, an irreversible beta-lactamase inhibitor, was compared to cefoxitin in the treatment of women with acute pelvic inflammatory disease (PID) with and without inflammatory mass(es). METHODS Participation in an open, prospective, randomized clinical trial was offered to all women given the clinical diagnosis of acute PID who required inpatient therapy. Neisser...

Abstract Background CRAB continues to threaten the healthcare facilities in developing nations and is one among commonest causes of hospital acquired infections our hospital. In December 2021, IDSA published AMR guidance 2.0, that stated Ampicillin- sulbactam as first choice for treating infections. We review clinical outcomes with adherence this guideline setting. Methods A descriptive study f...

BACKGROUND The treatment options for pneumonia involving multidrug-resistant Acinetobacter calcoaceticus-Acinetobacter baumannii (MDR Acb) complex are limited, and the optimal treatment has not been established. METHODS To compare the efficacy of tigecycline-based with sulbactam (or ampicillin/sulbactam)-based therapy for pneumonia involving MDR Acb complex, we conducted a retrospective study...

The activity of cefoperazone/sulbactam was compared with eleven other antimicrobial agents against 91 strains of the Bacteroides fragilis group known to be resistant to clindamycin and/or beta-lactam agents. Sulbactam alone possessed moderate activity against most strains and improved the activity of cefoperazone and ampicillin. Bacteroides distasonis strains were more resistant than other spec...

This study was undertaken to evaluate the in vitro activities of arbekacin-based combination regimens against vancomycin hetero-intermediate Staphylococcus aureus (hetero-VISA). Combinations of arbekacin with vancomycin, rifampin, ampicillin-sulbactam, teicoplanin, or quinupristin-dalfopristin against seven hetero-VISA strains and two methicillin-resistant S. aureus strains were evaluated by th...
