Growth and host interaction of mouse segmented filamentous bacteria in vitro

Abstract: The gut microbiota plays a crucial role in the maturation of the intestinal mucosal immune system of its host1,2. Within the thousand bacterial species present in the intestine, the symbiont Segmented Filamentous Bacterium (SFB) is unique in its ability to potently stimulate the postnatal maturation of the B and T cell compartments and induce a striking increase in the small intestinal Th17 responses3-5. Unlike other commensals, SFB intimately attaches to absorptive epithelial cells in the ileum and cells over… Show more

“…Single-cell sequencing demonstrated that single nucleotide polymorphism (SNP) mutations exist within disparate SFB genomes isolated from the same host (23). Current technology for SFB culture and passage in vitro is relatively unrefined (13,14). There are no simple single-cell sequencing methods available for detecting various SFB strains.…”

“…Ericsson et al and Schnupf et al established culturing methods for mouse SFB in vitro (13,14), although passaging of SFB in vitro is still problematic (13). Cultureindependent bioinformatic analysis could be used as a tool in finding candidate SFB functional genes.…”

“…Contrairement à la majorité des bactéries commensales 5 qui induisent une réponse IgA relativement modeste et des réponses T dominées par des réponses T régulatrices, notamment dans le côlon [18,[26][27][28], la SFB joue un rôle privilégié dans la maturation post-natale des réponses immunes innées et adaptatives chez son hôte [18,22] (Figure 2). Cette bactérie, cultivable seulement récemment [29], est apparentée au genre des Clostridium [30]. Elle a été identifiée dans de nombreuses espèces, des arthropodes aux mammifères, sur la base de sa morphologie très particulière et/ou de la détection de son ARN ribosomal 16S [30].…”
