Antimicrobial effect of human milk on Bordetella pertussis.
It has been demonstrated that human milk, unlike bovine milk, can reduce the viability of Bordetella pertussis. This antibacterial activity was not due to the presence of antibiotics or antibodies in the human milk. Reducing the level of available iron or increasing the concentration of lysozyme in bovine milk did not induce anti-B. pertussis activity. Analysis of total fatty acids revealed that human milk contained significantly more linoleic acid than bovine milk. However, the addition of linoleic acid to bovine milk did not inhibit the growth of B. pertussis.
