OBJECTIVES To investigate the molecular events involved in the development of quinolone resistance in enterococci. METHODS Clinical isolates of Enterococcus faecium and Enterococcus faecalis were exposed to inhibitory and subinhibitory concentrations of DX-619, ciprofloxacin, levofloxacin, gatifloxacin and moxifloxacin. Mutational frequencies were calculated and susceptibility changes were de...
The disc diffusion, Etest and agar dilution techniques were compared to evaluate the antimicrobial susceptibility profile of 70 Stenotrophomonas maltophilia isolates to seven antimicrobial agents. The S. maltophilia isolates were consecutively collected from May 2000 to May 2002 from individual patients, who were hospitalized in a private Brazilian hospital. The antimicrobial susceptibility tes...
Tuberculous meningitis (TBM) is the most lethal form of tuberculosis, and new treatments that improve outcomes are required. We randomly assigned adults with TBM to treatment with standard antituberculosis treatment alone or in combination with ciprofloxacin (750 mg/12 h), levofloxacin (500 mg/12 h), or gatifloxacin (400 mg/24 h) for the first 60 days of therapy. Fluoroquinolone concentrations ...
Results from garenoxacin dry-form broth microdilution MIC panels prepared commercially (Sensititre, TREK Diagnostics) were compared to reference frozen-form MICs to ensure the validity of the longer-shelf-life product. A total of 1078 organisms from seven major organism groups were used in this trial. All commercial MIC results were within +/- one log(2) dilution of reference garenoxacin values...
BACKGROUND Upper and lower respiratory tract infections (RTIs) account for a substantial portion of outpatient antibiotic utilization. However, the pharmacodynamic activity of commonly used oral antibiotic regimens has not been studied against clinically relevant pathogens. The objective of this study was to assess the probability of achieving the requisite pharmacodynamic exposure for oral ant...
BACKGROUND Shortening tuberculosis (TB) treatment duration is a research priority. This paper presents data from a prematurely terminated randomized clinical trial, of 4-month moxifloxacin or gatifloxacin regimens, in South India. METHODS Newly diagnosed, sputum-positive HIV-negative pulmonary TB patients were randomly allocated to receive gatifloxacin or moxifloxacin, along with isoniazid an...
