Curezone has a parasite gallery and there are pics on the net that you can Google.
Curezone also has some pictures of candida. I have found those pictures to be much more difficult ti find probably because people are not nearly as aware of candida problems as they are of parasites.
I would not try to do any candida killing until after at least a month of paracides, then a month of paracides plus zapping. The die off could be too overwhelming if you try to kill both bugs & candida at the same time as both activities cause a herx/die off reaction.
