It was my intention to address each of these as I found time, so thanks for asking for more clarity.
#2 - Candida Albicans in its normal yeast form is a commensal organism that has co-evolved with over 5600 other micro-organisms taking up residence in the intestinal tract and other tissues.
Only in its fungal (hyphal/mycelial) form is it an infectious agent that uses its cell wall, adhesion, phenotypic switching, and enzymes to spread and destroy tissues throughout the body. Many people commonly refer to Candida Albicans as a yeast infection when it is actually a fungal infection.
