| It may be that their main metabolic interaction is with bacterial commensals, rather than directly with the insect host. |
| This behaviour could be an attempt to dislodge parasites or commensals. |
| She says a few laboratories are making progress culturing consortia of human gut commensals in specialized environments called chemostats. |
