Treating a Staph Infection without antiobiotics?

I have a friend named Julia who turned vegan(not raw vegan) after contracting a staph-aureus infection by eating a contaminated piece of meat. That was 3 years ago. Her Doctor had to give her 2 treatment of antibiotic in order to kill those bugs. The last 2 months she cut herself and had to take an antibiotic treatment to treat t...he cut. However she feels that her intestinal flora is again showing some sign of staph/candidas infections. She does not want to go to the doctor again and get a new antibiotic treatment as she fears that her staphs are getting more strength. I told her to fast with orange/lemon juice and taking some acidophilus pills. What would you suggest in her case? She is 39. Thanks
