All showed valuable antimicrobial activity against the tested isolates. Oil from the bark of Cinnamomum zeylanicum (MBC90 = 500 ug/mL) however was found to be the most effective. Carvacrol (MBC90 = 600 ug/mL) and eugenol (MBC90 = 1000 ug/mL) also possessed strong antimycoplasmal activity.Conclusions: The results indicate that cinnamon bark oil, carvacrol and eugenol have strong antimycoplasmal activity and the potential for use as antimicrobial agents in the treatment of mycoplasmal infections.
