Tracking Immune and Microbiota Recovery

Researchers studied the recovery of both the immune systems and gut microbiota in patients recovering from bone marrow transplants. Before the donor cells are thriving enough to rebuild the immune system, patients are given antibiotics to keep them safe while they recover. These antibiotics also kill healthy gut microbiota, meaning both the patients' immune systems and gut bacteria start to recover around the same time.

Researchers at Sloan Kettering took blood and fecal samples from recovering patients to track the development of new immune cells and gut bacteria. It is accepted already that these two systems are linked, though the exact nature of the relationship is still under investigation.
