Yes, this problem depends upon the pH some, but more upon the Mineral ratios of one to another, which may vary depending upon the pH also!
In other words, the mineral amounts in ratios to each other or lack of to each other at different pH levels may provide the needed concentrations of the needed Minerals or Lack of thereof!
In other words, if you are correctly Balanced in your pH and this Balance is made up of the correct Electrical Energies from the correct Energy Releases, then the parasites may not Live in this environment!
Most problems from parasites may be from a Lack of enough Phosphates, which means that the body must contain enough Alkaline Minerals to Balance out the Phosphoric Acid from the Phosphates in order to maintain the pH Balance !
High Phosphates with the correct Alkaline Minerals may provide the body with the needed Oils and Complexed Carbohydrates and natural sugars, which parasites may not Live in this environment!
For the lower life forms as the pararsites are part of, may not live where the Electrical Energy Releases are of the more complexed forms which may be made from the High Mineralized Complexes bound with Phosphates!
