The microbiota of human plays an important role in the health improvement, and found abundant in the The preliminary study aimed to isolate and identify the gut microbiota of newborns for the assessment of prevalent Lactic Acid Bacteria (LAB) distribution. Thirty eight Thai newborns, 0-5 days old of both sexes were subjected for fecal samples collection. Forty five isolates of LAB and non-LAB bacteria were obtained from feces of newborns. The most prevalence LAB found in this population were 45% Enterococcus faecalis, 14% E. faecium, 11% E. hirae, 11% Lactobacillus paracasei, and 2% L. gasseri. Unusually, Gram-negative bacteria including Klebsiella pneumoniae, Enterobacter hormaechei, Escherichia fergusonii, Leclercia adecarboxylata, and Shigella flexneri were isolated among LAB strains on the selective MRS media. The gut microbiota was a great resource of beneficial LAB which was remarkably distributed among this
