Microbiome signature found in 11 week foetus

Even after your heart ceases to beat, a vital part of your body continues to thrive long after you're gone – your microbes. In a fascinating study exploring the field of necrobiology, researchers have discovered that the microbes residing within you during your lifetime not only persist postmortem but also play a crucial role in recycling your body to facilitate new life. This is life after death.


Lungs and Placentas of the foetus kin womb (11 weeks after conception) already reveal bacterial microbiome signature, which shows that bacteria may have colonised the lungs before the birth.

This is the first time that such a study has come out and the findings only increases the mystery on how microbial products reach the organs before birth and the role they play in the development of lungs and the immune system.

The findings have been revealed by a team led by Charitharath Vivek Lal of the University of the University of Alabama in Brimingham. They found that a fetal microbiome DNA signature was present in the lungs as early as the first trimester. They also came across placenta microbiome in the foetus

The study has been published in the American Journal of Respiratory and Critical care medicine.

For the study, 31 samples of lung and placenta tissues from foetus between 11 and 20 weeks of gestation were collected. The tests were done in labs at the Lee Kong Chjian School of Medicine at Singapore and at UAB.
