Definitions for lactobacillusˌlæk toʊ bəˈsɪl əs; -ˈsɪl aɪ
This page provides all possible meanings and translations of the word lactobacillus
a Gram-positive rod-shaped bacterium that produces lactic acid (especially in milk)
Any of many rod-shaped, nonmotile, aerobic bacteria, of the genus Lactobacillus, that ferment sugars to form lactic acid
Lactobacillus, also called Döderlein's bacillus, is a genus of Gram-positive facultative anaerobic or microaerophilic rod-shaped bacteria. They are a major part of the lactic acid bacteria group, named as such because most of its members convert lactose and other sugars to lactic acid. In humans they are present in the vagina and the gastrointestinal tract, where they make up a small portion of the gut flora. They are usually benign, except in the mouth where they have been associated with cavities and tooth decay. Many species are prominent in decaying plant material. The production of lactic acid makes its environment acidic, which inhibits the growth of some harmful bacteria. Several members of the genus have had their genome sequenced.
U.S. National Library of Medicine
A genus of gram-positive, microaerophilic, rod-shaped bacteria occurring widely in nature. Its species are also part of the many normal flora of the mouth, intestinal tract, and vagina of many mammals, including humans. Pathogenicity from this genus is rare.
Sample Sentences & Example Usage
The results show that after the use of oral antimicrobials, a shift occurs in the composition of the oral biofilm in a more healthy direction. Several species that can cause caries such as S. Mutans and Lactobacillus, decrease in prevalence, whereas the more harmless species increase in prevalence.
