    Abstract Nanoarchaea measuring less than 500 nm and encasing an average 600-kb compact genome have been studied for twenty years, after an estimated 4193-million-year evolution. Comprising only four co-cultured representatives, these symbiotic organisms initially detected in deep-sea hydrothermal vents and geothermal springs, have been further distributed in various environmental ecosystems worldwide. Recent isolation by co-culture of Nanopusillus massiliensis from the unique ecosystem of the human oral cavity, prompted us to review the evolutionary diversity of nanaorchaea resulting in a rapidly evolving taxonomiy. Regardless of their ecological niche, all nanoarchaea share limited metabolic capacities correlating with an obligate ectosymbiotic or parasitic lifestyle; focusing on the dynamics of nanoarchaea-bacteria nanoarchaea-archaea interactions at the morphological and metabolic levels; highlighting proteins involved in nanoarchaea attachment to the hosts, as well metabolic exchanges between both organisms; and highlighting clinical nanoarchaeology, an emerging field of research in the frame of the recent discovery of Candidate Phyla radiation (CPR) in human microbiota. Future studies in clinical nanobiology will expand knowledge of the nanaorchaea repertoire associated with human microbiota and diseases, to improve our understanding of the diversity of these nanoorganims and their intreactions with microbiota and host tissues.

    Abstract The authenticity of some of the very first works in the field of paleopathology has been questioned, and standards have been progressively established for the experiments and the interpretation of data. Whereas most problems initially arose from the contamination of ancient specimens with modern human DNA, the situation is different in the field of paleomicrobiology, in which the risk for contamination is well-known and adequately managed by any laboratory team with expertise in the routine diagnosis of modern-day infections. Indeed, the exploration of ancient microbiota and pathogens is best done by such laboratory teams, with research directed toward the discovery and implementation of new techniques and the interpretation of data.

    Abstract Methanogens are microorganisms belonging to the Archaea domain and represent the primary source of biotic methane. Methanogens encode a series of enzymes which can convert secondary substrates into methane following three major methanogenesis pathways. Initially recognized as environmental microorganisms, methanogens have more recently been acknowledged as host-associated microorganisms after their detection and initial isolation in ruminants in the 1950s. Methanogens have also been co-detected with bacteria in various pathological situations, bringing their role as pathogens into question. Here, we review reported associations between methanogens and bacteria in physiological and pathological situations in order to understand the metabolic interactions explaining these associations. To do so, we describe the origin of the metabolites used for methanogenesis and highlight the central role of methanogens in the syntrophic process during carbon cycling. We then focus on the metabolic abilities of co-detected bacterial species described in the literature and infer from their genomes the probable mechanisms of their association with methanogens. The syntrophic interactions between bacteria and methanogens are paramount to gut homeostasis. Therefore, any dysbiosis affecting methanogens might impact human health. Thus, the monitoring of methanogens may be used as a bio-indicator of dysbiosis. Moreover, new therapeutic approaches can be developed based on their administration as probiotics. We thus insist on the importance of investigating methanogens in clinical microbiology.
