Profiles of commensal and opportunistic bacteria in human milk from healthy donors in Taiwan

364Bacterial species composition in human milk samples from healthy donors in Taiwan are shown. The milk microbiota was measured using a molecular-based approach. Only four Lactobacillus species were detected in 7 samples, and bifidobacterial species were rare. However, the Staphylococcus aureus was commonly found in milk from healthy donors, and this species was detected in a total of 15 samples. Colostrum (C: C1 to C20) and transitional milk (T: T1 to T10) showed contrasting bacterial profiles. This confirms previous research showing that the human breast milk microbiota is unique to each mother.
