The present invention relates to a composition comprising an inventive combination of salt, sugar and lactic acid bacteria as an active ingredient to treat or prevent vaginosis. The inventive composition showed potent antibacterial activity through various experiments, for example, (1) the indirect inhibitory activity test from the growth of vaginosis causing bacteria by determining the change of pH and lactic acid level (Experimental example 1)； (2) the direct inhibitory activity test from the growth of vaginosis causing bacteria by determining the susceptibility of test sample (Experimental example 2)； (3) brief clinical tests, and finally confirmed that the combination showed potent antibacterial activity in the test. Accordingly, the inventive combination may be useful to alleviate, treat or prevent vaginosis in the form of a pharmaceutical composition, health functional food, food additive, topical composition, and detergent composition.
