to the liver and promote patient-derived xenograft tumour growth Figure 1 Fusobacterium translocate with primary colorectal cancer cells to the liver and promote patient-derived xenograft tumour growth Figure 1 | Fusobacterium translocate with primary colorectal cancer cells to the liver and promote patient-derived xenograft tumour growth. Bullman et al.10 showed that the same Fusobacterium species were present in paired primary and metastatic tumour samples from patients with colorectal cancer (CRC) and that the Fusobacterium-killing antibiotic metronidazole, but not erythromycin, inhibited patient-derived xenograft tumour growth.
