Time series strain tracking analysis post fecal transplantation identifies individual specific patterns of fecal dominant donor, recipient, and unrelated microbial strains.

The complex oscillating patterns of the appearance of fecal dominant donor, recipient or unrelated strains following extended times post FMT provide new insights into the dynamics of the microbial community interactions with the recipients following FMT. The result from our analysis has implications for the use of FMT to predictably change the biological functions of the gut community in metabolism and host immunity.
