There are several gram positive organisms--staph and strept come
to my mind from learning Micobiology many years ago to be a nurse.
But why worry about the organisms? Just try to improve your
general immune function with good diet, pure water, bowel
cleansing, Liver Flushing etc. I highly suggest going to
Ask Shelley and read at the top about Frequently Asked
Questions for improving general health. I have learning
much there and also you can go to Ask Andreas.
