http://www.buzzle.com/articles/candida-in-stool.html This seems like a reasonable article. It deals, specifically, with intestinal candidiasis (candida overgrowth in the gut.)
http://en.wikipedia.org/wiki/Candidiasis I happen to believe the outline of candida disorders laid out in this article. This article also addresses the difference between disorders reconized by mainstream medicine and those that are not. When somebody sells a book claiming to tie everything from depression and fatigue all the way to multiple sclerosis to the presence of candida, I, myself, am very skeptical. It also explains that "systemic candidiasis" is candidemia, which means candida in the blood, a major emergency - for which you do need conventional big gun medicine, not a change in your diet.
