We previously reported that inactivation of rdxA and/or frxA converted Helicobacter pylori from metronidazole sensitive to metronidazole resistant. To examine the individual roles of rdxA and frxA in the development of metronidazole resistance in H. pylori, we examined the status of rdxA and frxA from 12 pairs of metronidazole-sensitive and -resistant H. pylori isolates obtained following unsuc...

OBJECTIVE To characterize the elution and bioactivity of metronidazole and gentamicin sulfate polymerized, individually and in combination, with polymethylmethacrylate (PMMA). STUDY DESIGN In vitro experimental study. METHODS PMMA beads containing metronidazole (3 concentrations), gentamicin sulfate, or metronidazole and gentamicin sulfate were immersed in 5 mL of phosphate-buffered saline ...

OBJECTIVES Previous studies have shown that metronidazole, alone or in combination with spiramycin (250 mg/1 500 000 units, three times/day), is an effective treatment for active periodontitis, although the dose of metronidazole currently used (750 mg/day) could provide concentrations in gingival crevice fluid that are too low for the MICs of the involved pathogens. This study tested the in viv...

background: to compare the efficacy of metronidazole versus placebo in the control of gaseous symptoms inpatients with functional bowel disease. materials and methods: in the absence of organic or systemic diseases, all cases with chief complaints of bloating and normal laboratory tests were consecutively enrolled in this double-blind study. lactase deficiency and bacterial overgrowth were rule...

OBJECTIVES To assess the prevalence of, and the variation in, avoidable use of metronidazole in the Veterans Affairs (VA) healthcare system METHODS Barcode Medication Administration (BCMA) data were retrospectively assessed for all patients hospitalized between January 2006 and December 2010 in acute-care wards of all VA medical centres (VAMCs) with complete BCMA data and at least 10 acute-ca...

Metronidazole and furazolidone were compared for efficacy in 268 seven to 11 year old children infected with giardiasis. With metronidazole the cure rate was 82.3% and 80.0% in boys and girls respectively, while furazolidone showed an efficacy of74.4% and 71. 7% in the corresponding groups. The overall efficacy was 81.1 % with metronidazole and 73.3% with furazolidone. There were no signif...
