Disclosed herein are methods for inhibiting growth of oral pathogenic bacteria and alleviating an oral pathogenic bacteria-associated disorder using a culture of at least one lactic acid bacterial strain selected from the group consisting of Lactobacillus rhamnosus MP108 which is deposited at the China General Microbiological Culture Collection Center (CGMCC) under an accession number CGMCC 21225, and Lactobacillus paracasei MP137 which is deposited at the CGMCC under an accession number CGMCC 21224.

Disclosed herein are methods for alleviating an enteric pathogenic bacterium-associated disorder and inhibiting growth of enteric pathogenic bacteria using a composition containing cultures of Lactobacillus rhamnosus MP108 which is deposited at the China General Microbiological Culture Collection Center (CGMCC) under an accession number CGMCC 21225, and Lactobacillus paracasei MP137 which is deposited at the CGMCC under an accession number CGMCC 21224.

The present invention relates to lactic acid bacterial strains which are capable of producing or inducing the production of melatonin, for use in the production of melatonin in a subject. Preferred strains for such uses are capable of producing or inducing the production of adenosine. Therapeutic uses of such strains include the treatment or prevention of diseases associated with melatonin deficiency, for example infantile colic. Novel strains are also provided.

The present invention relates to: human-derived Lactobacillus fermentum MG4231 or Lactobacillus fermentum MG4244; and a pharmaceutical composition, a food composition, a quasi-drug composition and a health functional food for preventing or treating obesity-related diseases, all of which include the same as an active ingredient. A Lactobacillus fermentum MG4231 strain or MG4244 strain of the present invention exhibits an anti-obesity activity for inhibiting a lipase enzyme activity, inhibiting preadipocyte differentiation and inhibiting triglyceride accumulation, has an excellent ability to form colonies on the epithelial cells of a digestive tract by means of an excellent auto-aggregation ability, and has resistance to acid and bile, thereby being variously usable as a pharmaceutical composition, a food composition, a quasi-drug composition and a health functional food for the purpose of treating and preventing obesity-related diseases.

The invention relates to plasmids capable of expressing a protein targeting immune cells when transformed into a lactic acid bacterial cell, wherein the protein is chosen from the group consisting of murine and human CXCL12 1α; CXCL17 and Ym1. The invention further relates to lactic acid bacteria transformed with a said plasmid, as well as the use of said lactic acid bacteria for wound healing in humans and animals.

Described herein is a synergistic combination comprising a quorum-sensing inhibitor and/or postbiotic metabolite and an antibiotic. Typically, the postbiotic metabolite comprises at least one peptide. Related compositions, uses, and methods are also described, including methods for resensitizing resistant bacteria to an antibiotic, and methods of treating antibiotic-resistant infections, such as methicillin-resistant Staphylococcus aureus (MRSA).

Disclosed is a method for converting 10-hydroxy-2-decenoic acid to 10-hydroxydecanoic acid, the method including: reacting Lactobacillus bacteria having an ability to convert 10-hydroxy-2-decenoic acid to 10-hydroxydecanoic acid with 10-hydroxy-2-decenoic acid.

The present application relates to a Lactobacillus paracasei or progeny thereof. Specifically, the present application relates to Lactobacillus paracasei 207-27 and a composition, culture, food product or dietary supplement containing the same. The present application also relates to the use of Lactobacillus paracasei 207-27 and the composition, culture, food product or dietary supplement containing the same in medicine.

The invention provides a method and bacterial compositions for reducing or preventing an infection of a bodily tissue by a fungal microorganism by contacting the tissue with a composition comprising a purified Lactobacillus paracasei bacterium.

The present disclosure discloses a strain of Lactobacillus fermentum capable of preventing and/or treating periodontitis and an application thereof, belonging to the field of microbiology technology. The present disclosure has screened to obtain a strain of L. fermentum CCFM1139. The L. fermentum CCFM1139 can alleviate periodontitis by inhibiting formation of mixed bacterial biofilms of Porphyromonas gingivalis, Prevotella intermedia and Fusobacterium nucleatum, thereby reducing the amount of biofilm by 52.45%, and can reduce the content of TNF-α from 131.37 pg/mL to 83.31 pg/mL and IL-8 from 147.70 pg/mL to 121.12 pg/mL in a periodontitis cell model, reduce colonization of the P. gingivalis and the F. nucleatum in the oral cavity by 1-2 orders of magnitude, and reduce the amount of the alveolar bone resorption from 1838.0 μm to 805.7 μm.
