The present invention relates to a composition comprising at least one human milk oligosaccharide and/or a precursor thereof, for use in preventing and/or treating necrotizing enterocolitis in infants or young children born by C-section.

The present disclosure relates to an immune-enhancing composition comprising Lactobacillus rhamnosus LM1019 and starter strains. An immune-enhancing composition comprising Lactobacillus rhamnosus LM1019 and starter strains according to the present disclosure has an excellent immune-enhancing effect by increasing the amount of nitric oxide (NO) produced and improving the TNF- secretion ability. Also, since the immune-enhancing composition contains the starter strain, it can be used to produce fermented milk. Under the provisions of the Budapest Treaty on the International Recognition of the Deposit of Microorganisms for the Purposes of Patent Procedure, the Lactobacillus rhamnosus LM1019 strain was deposited with the international depositary authority: the Korean Culture Center of Microorganisms (KCCM) on Aug. 11, 2017, under the Accession Number: KCCM12308P.

Disclosed are a yoghurt for regulating intestinal tract, preparation method therefor, and use thereof, where the yogurt is prepared from raw materials comprising the following parts by weight: 90-97 parts of raw milk, Lactobacillus gasseri of (0.7-5)10.sup.8 CFU/100 g raw milk, Streptococcus thermophilus of (0.1-9)10.sup.10 CFU/100 g raw milk, Lactobacillus bulgaricus of (0.1-9)10.sup.10 CFU/100 g raw milk, Lactobacillus acidophilus of (0.5-7)10.sup.8 CFU/100 g raw milk, Lactobacillus plantarum of (0.5-7)10.sup.8 CFU/100 g raw milk, Lactobacillus paracasei of (0.1-9)10.sup.7 CFU/100 g raw milk, and other probiotics, and prebiotics such as inulin. The yogurt may regulate the balance of intestinal flora and prevent constipation and gestational diabetes in overweight and/or obese pregnant women during the gestation period.

A probiotic composition includes microbes and one or more barrier materials including, on a dry weight basis: about 40% to about 99% (w/w) lipid, and about 0% to about 59% (w/w) of: a carbohydrate, a protein, a polymer, and/or combinations thereof.
