Lactobacillus under the Microscope

Lactobacillus is a genus of gram-positive rod-shaped bacteria that is a major part of the lactic acid bacteria group. Most bacteria in this group convert lactose and other sugars to lactic acid. In humans Lactobacillus is present in the vagina and the GI tract, where they make up a small portion of the gut flora. Typically Lactobacillus bacteria are benign, except in the mouth where they have been known to cause cavities and tooth decay.
