As far as I know, the octaves will have less power to kill than the actual MOR of a pathogen. The higher (or lower) harmonics will be less effective. They will have an effect but the MOR is the desired one. It is the frequency that resonates hardest with the pathogen.
MOR - mortal oscillatory rate. It is the one that shakes the pathogen the hardest, either breaking it or deactivating it.
