Background: Intestinal colonization of the newborn is essential for establishment, maturation and maintenance of the gut mucosal barrier. The greatest difference between the microbiota of breast milk and Infant formula infants feeding is the numbers and species composition of Bifidobacteria. In this study, we tried to identify the native Bifidobacterium isolates obtained from the human’s breast milk and the feces of their paired infants in rural areas of Markazi Province in 2015.
Materials and Methods: In this descriptive study, 28 samples from mothers’ milk and 28 samples from paired infants feces were collected and cultured. Suspicious colonies were picked up and confirmed by phenotypic identification and finally specific primers were designed for genotypic detection by PCR assay. Finally, the results were analyzed using spss18 software.
Findings: In this study, amongst Fifty-six samples, 31 (55%) different Bifidobacterium species including 15 (36%) B. bifidum, 14 (34%) B. longum, and, 12 (29%) B. 1 were isolated. Out of which, 12 (29%) isolates including B. longum (6), B. breve (4) and B. bifidum (2) were shared between six mother-infant pairs. The correlation coefficient of bifidobacteria isolated from breast milk against their feces was +0.821 (p-value <0.05).
Conclusion: By observing the 29 percent contribution and the positive correlation coefficient between breast milk and fecal bifidobacterium in our study, it probably be acknowledged that the main source of intestinal bifidobacterium in the early stages of birth is breast milk.
