“…For example, 90% of the bacterial species in termite guts are not found elsewhere (17). Such specialization, while increasing efficiency, comes with a cost: for every animal species that goes extinct, an unknown number of unique bacterial lineages that have evolved to depend on this animal niche disappear as well (18).…”

In the last two decades, the widespread application of genetic and genomic approaches has revealed a bacterial world astonishing in its ubiquity and diversity. This review examines how a growing knowledge of the vast range of animal–bacterial interactions, whether in shared ecosystems or intimate symbioses, is fundamentally altering our understanding of animal biology. Specifically, we highlight recent technological and intellectual advances that have changed our thinking about five questions: how have bacteria facilitated the origin and evolution of animals; how do animals and bacteria affect each other’s genomes; how does normal animal development depend on bacterial partners; how is homeostasis maintained between animals and their symbionts; and how can ecological approaches deepen our understanding of the multiple levels of animal–bacterial interaction. As answers to these fundamental questions emerge, all biologists will be challenged to broaden their appreciation of these interactions and to include investigations of the relationships between and among bacteria and their animal partners as we seek a better understanding of the natural world

“…The hindguts of termites and Cryptocercus accommodate bacteria belonging to more than 20 phyla and largely consisting of novel lineages that are unique to termites and without cultured representatives (Hongoh 2010;Berlanga et al 2009;2011;Dietrich et al 2014;Tarayre et al 2015). Among the lower termites examined, the phyla Spirochaetes, Proteobacteria, Firmicutes and Bacteroidetes predominate, but other phyla are also represented, including Actinobacteria, Synergistetes, Verrucomicrobia and Elusimicrobia [formerly 'Candidatus phylum Termite Group 1' (TG1) and 'Candidatus phylum Termite Group 2' (TG2)].…”

“…In higher termites, Spirochaetes, 'Candidatus phylum TG3' and Fibrobacteres are the dominant groups. Distinct termite species harbor different bacterial species with community structures specific to the host species, but most of those bacteria belong to phylogenetic clades that are unique to termites and are shared among diverse termite species (Hongoh 2010;Mikaelyan et al 2015). While Firmicutes and Bacteroidetes are generally more abundant in cockroaches than in termites, Spirochaetes are absent or have yet to be described in omnivorous cockroaches.…”

The rapid growth in microbiome research, particularly during the last 15 years, has revealed the crucial contributions of microbial communities to numerous physiological functions in animals, including digestion, immunity and reproduction.The permanent coexistence of these various bionts forms the holobiont (namely, the host and its microbiota). This review describes the relationships between xylophagous insects and their microbiota in an attempt to understand the characteristics that have determined bacterial fidelity over generations and throughout evolutionary history.Symbiotic interactions have probably played a central role in the evolutionary success of these insects, allowing their adaptation to unexploited ecological niches that are nutritionally deficient and/or unbalanced. Moreover, insect symbionts have provided the enzymatic capabilities that enable the synthesis of nutrients (carbon and nitrogen sources for the host) from recalcitrant plant polymers (cellulose, hemicellulose, pectin or lignin).
