Actually most of the serious bacteria are gram negative.
But MMS seems to work on Lyme bacteria which is gram positive. I think there is more to this MMS riddle than we yet know.
part of what it does is stimulate mitochondrial function, reports of people losing weight (fat) when not trying to, when they started MMS (that is from increased metabolism, from mitochondrial function)
but, aside from weight loss, all cells have a mitochondria (including immune cells), and in 1 of the videos by andreas kalcker, he states "we saw immune cells (I think he said leukocytes, but I am unsure), and they were moving at 10 times their normal rate, after the person took MMS"
meaning they are 10 times as active...
imagine an immune response that was 10 times the normal persons?
that is part of the mystery, right there....
