OBJECTIVE
To evaluate the antibacterial activity of the essential oil of Myrtus communis (M. communis) L. against Erysipelothrix rhusiopathiae (E. rhusiopathiae) in vitro.
METHODS
Wild populations of M. communis collected from Khuzestan and Lorestan provinces, Southwest Iran, were examined for antibacterial activity and chemical variability in leaves. The in vitro antibacterial activity against E. rhusiopathiae was performed by agar disc diffusion and micro-dilution assays.
RESULTS
The essential oils of M. communis have strong antibacterial against E. rhusiopathiae in both assays. The results showed that the major components of the oil were α-pinene (22.3%-55.2%), 1,8-cineole (8.7%-43.8%) and linalool (6.4%-14.5%). The inhibition zones and MIC values for bacteria which were sensitive to the essential oils of M. communis were in the range of 14.7-27.0 mm and 0.031-0.25 mg/mL, respectively.
CONCLUSIONS
This study demonstrates that products with valuable antibacterial activity can be produced from leaves of M. communis against E. rhusiopathiae.
