In recent research, a microbiology student, Emma Richards, has garnered attention for her striking visual demonstration of the antibacterial effects of human breast milk. While the nutritional benefits of breast milk for infants have long been established, this experiment provides compelling empirical evidence of its ability to combat harmful bacteria.
Richards, a first-year biosciences student at a college in Devon, England, conducted an experiment using nine petri dishes, all inoculated with the bacteria M. Luteus. She introduced a disk soaked in breast milk to the center of each dish, using samples from two nursing mothers. The samples were categorized as BmA, sourced from a mother nursing a 16-month-old, and BmB, from a mother feeding a three-year-old.
The results were visually striking. “The white areas surrounding the disks indicate the zones where the proteins in the milk have inhibited bacterial growth,” Richards elaborated in her post. She noted that similar experiments with E. coli and MRSA bacteria yielded comparable results, and she intends to explore colostrum in future trials.
Richards’ findings quickly went viral, captivating audiences who were thrilled to witness concrete evidence of breast milk’s protective capabilities against infections in infants. Interestingly, while not intentionally selecting her sample sources based on age, the inclusion of mothers nursing toddlers serves as a testament to the ongoing benefits of breast milk beyond infancy, addressing common misconceptions regarding extended breastfeeding.
It is essential to recognize that regardless of whether a baby is breastfed or formula-fed, they receive immune support from their mothers. Antibodies are transmitted through the placenta during pregnancy, providing a foundational immune boost at birth. Thus, both breast milk and formula serve to benefit a child’s health in different ways.

In conclusion, this experiment not only showcases the remarkable properties of human milk but also reinforces the importance of feeding methods—whatever the choice may be—for the health of infants.
