What is Streptococcus Thermophilus and how do I correct this?

Streptococcus thermophilus is a strain of "friendly" bacteria that normally live in our digestive, urinary, and genital systems without causing disease. An imbalance in this strain can exacerbate conditions concerning these areas of the body. Streptococcus thermophilus is commonly used to produce fermented dairy foods such as yogurt. It is also used in dietary supplements.
