CABALLERO-MENDEZ, Lyda et al. Antibacterial capacity of bovine, goat, buffalo and human milk and colostrum, against bacteria of clinical importance in animal and human health. rev.udcaactual.divulg.cient. [online]. 2023, vol.26, n.2, e2100.  Epub 08-Nov-2023. ISSN 0123-4226.  https://doi.org/10.31910/rudca.v26.n2.2023.2100.

Breast milk and colostrum from various species is a body fluid with beneficial effects on the health of those who receive them because it is the first line of defense, promoting the development, growth, and protection of newborn. Its antibacterial activity against pathogens of clinical importance suggests as an attractive therapeutic alternative in the face of the growing bacterial resistance facing animal, and human medicine. This work compared the antimicrobial effect of samples of mature milk and colostrum from bovine, caprine, buffalo, and human species. Mass sowing was carried out with ATCC strains of Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus and Escherichia coli in Mueller-Hinton, the milk and colostrum samples were diluted in peptone water and placed in the boxes using sterile sensidiscs impregnated with different dilutions, they were incubating and subsequently the inhibition zone around the discs was measured, indicating their antimicrobial capacity. Little antibacterial activity of milk vs. colostrum was demonstrate. Furthermore, human, goat, and buffalo milk and colostrum showed antibacterial activity against P. aeruginosa, and only human, goat, and buffalo colostrum showed activity against K. pneumoniae. The results obtained demonstrated that milk and colostrum have antimicrobial effects.
