aimed to evaluate the dominant bacteria
existing in breast milk of healthy women using the 16S rDNA
amplified gene approach.DNAextracted frombiologicalsampleswas
used as a template for PCR amplification of 16S rDNA gene sequences
with universal bacterial primers. Denaturing gradient gel electrophoresis
(DGGE) was used to analyze the PCR products, then clone
libraries of 16S rDNA gene sequences from 4 mothers (2 from each
group) were constructed. The results suggest that eachwoman had a
specific bacterial pattern in her breast milk and that breast milk of
healthy women is a source of commensal bacteria to the infant gut.
