Diet shapes the gut microbiota of the omnivorous cockroach <i>Blattella germanica</i>

The gut microbiota of insects contributes positively to the physiology of its host mainly by participating in food digestion, protecting against pathogens, or provisioning vitamins or amino acids, but the dynamics of this complex ecosystem is not well understood so far. In this study, we have charac...
