We can not stop discovering the benefits of breast milk. An American study has revealed that one of its proteins will help fight microbes that have resisted even so far very powerful antibiotics.
Microbial resistance, a plague
- Microbial resistance to antibiotics is a public health concern. In particular, it poses a great problem in hospital environments, where extremely virulent microbes such as staphylococcus aureus or streptococcus pneumonia proliferate. Responsible for serious infections, these pathogens even resist very powerful antibiotics, such as penicillin.
Breast milk, the ally of antibiotics
- Breast milk has more than one trick in its bag! In addition to being the natural food best suited to the needs of the infant, it contains a protein called Hamlet (Alpha lactalbumin modified killer tumor cells). The study published in May 2013 in the American medical journal Plos one revealed that Hamlet protein weakens the resistance of "super microbes" to antibiotics and has the potential to reduce the amount of antibiotics needed to fight infections. It therefore allows the use of more common and less potent antibiotics to combat resistant pathogens.
- For now, experiments have been conducted in the laboratory and on animals. It appears that bacteria seem to have difficulty developing resistance and that they die in large numbers after being exposed to Hamlet.
- The Hamlet protein has another great interest: being a naturally occurring substance in human milk, it does not exhibit the toxic side effects that can be observed when using very potent antibiotics.
