Most women were colonized by L. crispatus (32%), followed by L.
Which type of bacteria is Lactobacillus?
Lactobacillus, (genus Lactobacillus), any of a group of rod-shaped, gram-positive, non-spore-forming bacteria of the family Lactobacillaceae. Similar to other genera in the family, Lactobacillus are characterized by their ability to produce lactic acid as a by-product of glucose metabolism.

Lactobacillus isolates and several other strains of bacteria co-isolated on MRS medium from gastrointestinal ecosystem and fermented food products could be identified using DNA fingerprints generated by restriction endonucleases.
