The latter is composed of native oral microbiota and it is accumulated on teeth surfaces. Several antiseptic agents are used widely to inhibit bacterial growth [1,2]. However, these substances have adverse effects. In the current study, six plants extracts namely, chamomile, dittany, lemon balm, rosemary, saffron and sage, were tested as potential natural antimicrobial agents. The antimicrobial activity of plants extracts was studied towards Gram-positive strains belonging to Streptococcus species related to the oral health. Fourier transform infrared spectroscopy (FT-IR) was applied in order to evaluate the changes in the cellular composition of target bacterial cells after their exposure to extracts of both plants. 1 pp. LOMv1.0 creator LOMv1.0 Project Final Beneficiary LOMv1.0 Project Executing Organisation 2013 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text 1177242 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/2731/2/2731_ECCO%202013.pdf URI http://hdl.handle.net/10795/2731 LOMv1.0creator 2016-04-19T09:03:14Z LOMv1.0validator 2016-04-19T09:03:14Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
