Antibacterial activity of J. excelsa EO against A. actinomycetemcomitans. (A) Bacteria growth was inhibited by pure (0) or 1/10 diluted EO (10); inhibition was statistically significant in comparison with controls (cnt) (p < 0.05, indicated by the *); (B) higher EO dilutions (100 or 1000) were ineffective; (C) XTT assay revealed a similar activity between CHX and EO (10), statistically different towards controls (* p < 0.05) for both biofilm (left) and planktonic (right) cells; (D) CFUs counts showed that CHX and EO (10) determined a similar significant reduction of about 1.5 logs in comparison with control (* p < 0.05) for both biofilm (left) or planktonic (right) cells. Data are expressed as mean ± standard deviation.
