It is well documented in the scientific literature that ozone-oxygen mixtures inactivate microorganisms including bacteria, fungi and viruses (Hoff, J.C., 1986. Inactivation of microbial agents by chemical disinfectants. EPA 600 S2-86 067. Office of Water, U.S. Environmental Protection Agency, Washington, DC; Khadre, M.A., Yousef, A.E., Kim, J.-G., 2001. Microbiological aspects of ozone applications in food: a review. J. Food Sci. 66, 1242-1252). In the current study, delivery and absorption of precisely known concentrations of ozone (in liquid media) were used to inactivate virus infectivity. An ozone-oxygen delivery system capable of monitoring and recording ozone concentrations in real time was used to inactivate a series of enveloped and non-enveloped viruses including herpes simplex virus type-1 (HHV-1, strain McIntyre), vesicular stomatitis Indiana virus (VSIV), vaccinia virus (VACV, strain Elstree), adenovirus type-2 (HAdV-2), and the PR8 strain of influenza A virus (FLUAVA/PR/8/34/H1N1; FLUAV). The results of the study showed that ozone exposure reduced viral infectivity by lipid peroxidation and subsequent lipid envelope and protein shell damage. These data suggest that a wide range of virus types can be inactivated in an environment of known ozone exposure.

The antibacterial activity of various saturated fatty acids (SFA) and unsaturated fatty acids (USFA) against different oral pathogens which are implicated in the cause of dental caries, stomatitis, gingivitis, and periodontitis was examined. The saturated fatty acids Pa, StA and ArA, and the unsaturated omega-7 fatty acids PLA and omega-9 fatty acids OA showed either none to low antimicrobial activity against all of the 12 oral pathogenic strains used in this study. In contrast, the omega-3 PUFAs, ALA, SDA, EPA and DHA, and the omega-6 PUFAs, LA, GLA, and AA showed considerable antimicrobial activity against 8, 7, 6 and 5 strains, and 6, 10 and 5 strains, respectively. In particular, the omega-3 and omega-6 PUFAs showed strong antimicrobial activity against Porphyromonas gingivalis KCTC 381, the cause of periodontitis, and against Aggregatibacter segnis KCTC 5968, Fusobacterium nucleatum subsp. Polymorphum KCTC 5172 and Prevotella intermedia KCTC 25611, all organisms implicated in the cause of gingivitis. To date, no bacterial resistance to free fatty acids has been encountered and no resistance phenotype has emerged. Therefore, these results suggest that PUFAs may be useful in the development of therapeutic agents for oral diseases, and in particular, in the development of agents that have minimal side effects and against which there is no bacterial resistance.
