FIG. 1.

Antimicrobial activities of oregano and cranberry extract mixtures against H. pylori at pH 7.0 and 37°C after 48 h of incubation (100 μl extract mixture per disk with 0.1 mg equivalent phenolic content). Each experiment consisted of three replicates with various phytochemical concentrations. Each experiment was repeated three times. The error bars represent ±1 standard deviation from the mean. Bars with the same letters are not significantly different. Statistical analysis was done by analysis of variance; P < 0.05. Controls consisted of disks with distilled water only.
