Although Helicobacter pylori is associated with gastric cancer, bacterial communities that reside in the stomach are mostly unacknowledged. A new study shows that some gastric bacterial communities have emigrated from our mouth, prefer certain neighbours and prefer certain environments. By understanding the interactions of these bacteria, we hope to understand the environment most conducive to gastric cancer carcinogenesis.
