Lactobacillus gasseri

Lactobacillus gasseri is a species in the genus Lactobacillus identified in 1980 by François Gasser and his associates.
L. gasseri is a normal inhabitant of the intestines of men and women and lower reproductive tract in healthy women. It is one of the four main species of Lactobacillus considered to be the major part of the vaginal microbiota, along with Lactobacillus crispatus, Lactobacillus jensenii, and Lactobacillus iners.
Lactobacillus gasseri produces gassericin A, a bacteriocin. It also produces Lactocillin.
Its 1.89 Mbp genome was sequenced in 2008.
Its strain Lg-36 eliminates C. difficile infection after taking antibiotics.
