One interesting article to read:

excerpt:
" Antibiotics will wipe out all of the bacteria in the body within a period of 5 to 7 days. Some of the species will never return leading to permanent population shifts that can remain for a lifetime unless corrected. These population shifts can form the foundation for diseases and conditions that follow. Systemic fungal candida is created by the imbalances caused by Antibiotics . Without the bacteria present, and the massive shifts within this ecosystem, fungal candida will flourish and subsequently play a role in determining which bacteria re-establish themselves and to what degree that is possible."
