question for shroom or anyone who knows

I have recently posted a lot about stuff i have read on yeast only thriving in the intestines. that it does not truly invade organs and other parts of the body because it does not actually travel in the blood stream. if this is actually true, then how do we get rashes and fungal infections under toenails and things like that.

any ideas?

here was what i read on one site:

Many people have an erroneous belief that the Candida itself enters the blood stream, allowing it to be deposited elsewhere, such as the brain. Unless the immune response is completely depleted, as in AIDS, Candida is quickly destroyed in the blood. The real damage done by Candida is to the intestinal epithelial barrier, allowing the absorption of serious toxic agents and chemicals, which then enter the blood and affect numerous organs, including the brain.
