How Parasites, Germs and Bacteria are listed
Her question was not super clear, but the book lists all parasites under “P” parasites. Bacteria may be listed under Family or Genus so is a little trickier. I have been shown how to do this if the question arises with a specific Bacteria which is unlisted. You have to step up to the family group frequency reference, which covers a few hundred bacteria within the same species., or use the general Bacteria Mycoses setting.
