Lactobacillus gasseri explained

Lactobacillus gasseri is a species in the genus Lactobacillus identified in 1980 by François Gasser and his associates.^{[1] [2]}

L. gasseri is a normal inhabitant of the intestines and lower reproductive tract in healthy women.^[3] It is one of the four main species of Lactobacillus considered to be the major part of the vaginal flora, along with Lactobacillus crispatus, Lactobacillus jensenii, and Lactobacillus iners.^[4]

Lactobacillus gasseri produces gassericin A, a bacteriocin.^[5] It also produces Lactocillin.^[6]

Its 1.89Mbp genome has been sequenced in 2008.^[7]
