Using cutting edge high through-put DNA sequencing, Sporometrics CEO Dr. James Scott and his colleagues investigated the bacterial make-up of faeces from young babies and the homes where the babies lived.

Scott’s group found a significant overlap in bacterial communities in a baby’s faeces and dust from their home, suggesting that a baby may be sharing their gut bacteria with the environment and vice versa.

This finding may have long-ranging implications on how our environments may influence our lives. How much of a personal imprint do we leave on our home? When we move to a new home, does the microbial imprint of the former occupants have the potential to affect us? And are these effects good or bad? Sorting out these interesting questions will be the focus of Scott’s future research.
