Hi! I am no expert on genetics since I am trained as a Chemical Engineer, I may not be able to answer your question fully. As far as I know, genetic drift cannot be stopped from occurring since it is an event based on random chance. In bacteria, we can rather talk about mutations, which would happen over a long period. In our case, the envisioned therapy is very short term: injection, therapy, and removal. Therefore, current projections do not give us any reason to be concerned about the possibility of bacterial genetic drift or mutation.

All the best,
