I don't think you understood my enquiry. I too have candidiasis due to the destruction of my gut flora having taken years of antibiotics. What I wanted to know, was why some people who have tested positive for HIV, do not appear to suffer from candidiasis as we do, despite them being supposedly immuno-compromised.

You answered a lot of your own question just now.  People who test HIV positive are put on an a lot of immune suppressing drugs including antibiotics.   The primary reason for Candida overgrowth is the use of antibiotics, which creates an alkaline terrain in the areas the Candida is found and that the Candida thrives in.  The areas of the body where Candida is normally found are naturally acidic from the flora to keep Candida and pathogens under control.  Killing the flora reduces the acid formation leading to an alkaline state that turns on the Candida growth gene and allows the Candida to convert in to its damaging fungal state.

Another drug that HIV+ people are frequently given is AZT or its analogues.  Problem is that this drug is EXTREMELY immunosuppressive and in fact is one of the leading causes of AIDS.  This sis because the drug destroys the bone marrow leading to a complete collapse of the immune system.  The resulting opportunistic infections and the drop in CD4s due to the bone marrow destruction lead to the AIDS diagnosis.

So the use of pharmaceutical drugs in HIV+ individuals is a major reason for incidences of Candida overgrowth in these individuals.
