Statistical tests for differences in the inhibitory activity of the three ethnobotanical usage groups: Group 1 includes plants used for SSTI (n=25); Group 2 includes plants used medicinally, but not on the skin (n=28); and Group includes plants with no ethnomedical application (n=51). (a) One-way ANOVA tests were performed. These results indicate that there was no significant difference in the inhibition of planktonic growth (p > 0.05) between ethnobotanical usage groups. There was, however, a significant difference in the inhibition of biofilm formation (p< 0.05) between groups. (b) Multiple comparison analysis using the Bonferroni method was performed on the data for anti-biofilm activity. A significant difference in activity of Groups 1 and 3 is evident.
