Abstract
The intestines of mice are colonized by diverse, as-yet-uncultivated bacteria. In this report, we describe the isolation, culture, genotypic and phenotypic characterization, as well as taxonomic classification of three novel anaerobic bacterial strains derived from the caecal contents of C57BL/6J male mice. According to the phenotypic and genotype-based polyphasic taxonomy, we propose three novel species within the family Oscillospiraceae. They are Acutalibacter caecimuris sp. nov. (type strain M00118T=CGMCC 1.18042T=KCTC 25739T), Acutalibacter intestini sp. nov. (type strain M00204T=CGMCC 1.18044T=KCTC 25741T) and Neglectibacter caecimuris sp. nov. (type strain M00184T=CGMCC 1.18043T=KCTC 25740T).

Abstract
A strong correlation between gut microbes and host health has been observed in numerous gut metagenomic cohort studies. However, the underlying mechanisms governing host-microbe interactions in the gut remain largely unknown. Here we report that the gut commensal Christensenella minuta modulates host metabolism by generating a previously undescribed class of secondary bile acids with 3-O-acylation substitution that inhibit the intestinal farnesoid X receptor. Administration of C. minuta alleviated features of metabolic disease in high fat diet-induced obese mice associated with a significant increase in these acylated bile acids, which we refer to as 3-O-acyl-cholic acids. Specific knockout of intestinal farnesoid X receptor in mice counteracted the beneficial effects observed in their wild-type counterparts. Finally, we showed that 3-O-acyl-CAs were prevalent in healthy humans but significantly depleted in patients with type 2 diabetes. Our findings indicate a role for C. minuta and acylated bile acids in metabolic diseases.

Abstract
Numbers of new and revised microbial taxa are continuously expanding, and the rapid accumulation of novel bacterial species is challenging to keep up with in the best of circumstances. With that in mind, following the template of reports on prokaryotic species isolated from humans, this is now the second publication summarizing new and revised taxa in non-domestic animal species in the Journal of Clinical Microbiology. The majority of new taxa were obtained as part of programs to identify bacteria from mucosal surfaces and the gastrointestinal tract from healthy wildlife. A few notable bacteria included new Erysipelothrix spp. from mammalian and aquatic sources and a novel Bartonella spp. isolated from a rodent, both of which could be considered members of emerging and re-emerging genera with pathogenic potential in humans and animals.

Abstract
We report the complete genome sequence of Tissierella sp. strain Yu-01 (=BCRC 81391), isolated from the feces of black soldier fly (Hermetia illucens) larvae. This fly has increasingly been gaining attention because of its usefulness for recycling organic waste. The genome of strain Yu-01 was selected for further species delineation.
