| | The preservation of the symbiont's health is of paramount importance to the Trill, and if one must be sacrificed to save another, the Trill will invariably give up his/her own to save the symbiont's life. | | | The commission was set up to determine which Trill could receive the honor of joining, and tended to the medical needs of the symbionts. | | | The process of joining links the cerebral cortex of both host and symbiont, thus intermingling the previous experiences from other hosts with the new host to form a new unique identity |

| | These worms harbor a microbial community of five co-occurring symbionts with very different metabolic pathways and evolutionary origins. | | | In addition to the interactions of the symbionts with their hosts, these associations are unique in that at least some of the oligochaete symbionts also share a mutualistic relationship with each other. | | | Thus, these symbioses offer the rare opportunity to not only identify the genomic differences and similarities that contribute to the diverse interactions between bacteria and their eukaryotic hosts, but also to examine the metabolic and genetic interactions within the symbiotic bacterial consortium. |
