Lactobacillus acidophilus:This bacterium is a natural component of the mouth, intestinal tract, and other areas in both humans and animals. As part of the normal flora, it plays a role in preventing the excessive growth of potentially harmful bacteria by sustaining an acidic environment. Certain bacteria, including L. acidophilus, are often referred to as "probiotics" because they can aid the body in maintaining or restoring a healthy balance of beneficial bacteria. The use of antibiotics can significantly reduce the body's normal flora. To mitigate this side effect, some healthcare providers suggest using probiotics. L. acidophilus is present in milk, fermented foods with "active cultures," and is available in supplement form. For more information, see probiotics.
