A photo showing samples of breastmilk fighting harmful bacteria in Petri dishes is going viral on Facebook.

The photo, posted by a biology student in England, features nine Petri dishes completely colonized with the bacteria M. Luteus, except in the center, where tiny puddles of breastmilk have created what looks like a “wall” of protection around themselves:

Vicky Green, said she had similar results with Petri dishes full of e.Coli and MRSA.

She wrote: “I’m a first year Biosciences student and I’m doing this for my microbiology research project.

The first sample(BmA)is from a mother feeding a 15 month old and the second(BmB) is from a mother feeding a 3 year old. I’m also doing colostrum in a couple of weeks.

So proud…here you have 9 Petri dishes containing the bacteria M. Luteus.

The white spots in the middle are discs soaked in two samples of breastmilk. See the clear bit around the discs- that’s where the proteins in the milk have inhibited the bacteria! I’m so excited!!!

It also worked with E. coli and had a fairly good go at MRSA too….the future is bright, the future is breastmilk.”

YourPediatrician.com explains how this is possible:

“About 80 percent of the cells in breast milk are macrophages, cells that kill bacteria, fungi and viruses. Breast-fed babies are protected, in varying degrees, from a number of illnesses, including pneumonia, botulism, bronchitis, staphylococcal infections, influenza, ear infections, and German measles. Furthermore, mothers produce antibodies to whatever disease is present in their environment, making their milk custom-designed to fight the diseases their babies are exposed to as well.”

Her post has been shared over 26,000 times with many comments thanking her for doing the research, while other skeptics are not so convinced.

It certainly is amazing to see!

  • wow that is great to see and very interesting! great research there! it will be very useful in the future


  • I always knew breast milk was powerful good stuff, didn’t realise it was to this extent. Amazing


  • Very impressive! Hopefully this is just the beginning of the research.


  • This is a great article detailing the research which as been done and what they intend to do next.
    This is why a lot of Mums who are unable to breastfeed for any reason are so disappointed.
    I know of 2 mums who had to switch their babies to bottle feeding becuase their milk had practially no nutrition in .t
