Differences in the patterns of inhibition of essential oils. Upper panel: principal component analysis biplot of inhibitory patterns 18 Bcc strains (centroids) treated with different EOs and ciprofloxacin (C+). The percentage of variance explained by the first two principal components is reported. Lower panel: values of pairwise comparisons (Kruskal-Wallis test and Bonferroni error protection) between EOs and C+. n.s.: not significant; * ; ** ; *** .
