Increased relative abundance of Fusobacterium species contributes to the difference in intestinal bacterial composition between healthy individuals and patients with colorectal cancer (CRC). A new study now reveals that live Fusobacterium originating from primary CRC associate with liver metastasis, suggesting a potentially important function for this bacterial genus in metastatic tumour growth.
