Two strains of a gram-positively staining, obligately anaerobic, non-spore-forming, rod-shaped bacterium, designated strains 111-13A and 111-35T, were isolated from human faeces. Analysis of the 16S rRNA gene sequences indicated that these strains were members of the Clostridium coccoides rRNA group of organisms. The nearest relatives of the unknown bacterium were Eubacterium formicigenerans (having a sequence similarity of 94%) and an uncultured bacterium (similarity > 99%). Characterization…

Sharpea azabuensis gen. nov., sp. nov., a Gram-positive, strictly anaerobic bacterium isolated from the faeces of thoroughbred horses.

Four bacterial strains isolated from the fresh faeces of four thoroughbred horses in Japan are considered to represent a novel species of a new genus belonging to the Clostridium subphylum cluster XVII, for which the name Sharpea azabuensis gen. nov., sp.

Anaerotruncus colihominis gen. nov., sp. nov., from human faeces.

It is proposed that the unknown bacterium should be classified in a novel genus as Anaerotruncus colihominis gen. nov., sp.nov, based on phylogenetic and phenotypic evidence.

Hungatella effluvii gen. nov., sp. nov., an obligately anaerobic bacterium isolated from an effluent treatment plant, and reclassification of Clostridium hathewayi as Hungatella hathewayi gen. nov., comb. nov.

Both C. hathewayi DSM 13479(T) and strain UB-B.2(T), isolated from an industrial effluent anaerobic digester sample, were identified as representatives of a new genus of the family Clostridiaceae and showed phenotypic differences from the members of rRNA gene cluster XIVa of the genusclostridium.

Sporofaciens musculi gen. nov., sp. nov., a novel bacterium isolated from the caecum of an obese mouse.

It is proposed that strain WCA-9-b2T represents a novel species within a novel genus, for which the name Sporofaciens musculi gen. nov. is proposed.

Reclassification of the Clostridium clostridioforme and Clostridium sphenoides clades as Enterocloster gen. nov. and Lacrimispora gen. nov., including reclassification of 15 taxa.

Two separate clades that include misclassified Clostridium species which phylogenetically lie within the family Lachnospiraceae are proposed to be reclassified, known for being benign members of gut microbiomes and for their plant-degrading capabilities.

Clostridium glycyrrhizinilyticum Sp. Nov., a Glycyrrhizin‐Hydrolysing Bacterium Isolated from Human Faeces

It is proposed that strains ZM35T and ZM38 be assigned to a novel species named Clostridium glycyrrhizinilyticum, which is a Gram‐positive, obligate anaerobic, non‐spore‐forming and rod‐shaped bacteria.

Stomatobaculum longum gen. nov., sp. nov., an obligately anaerobic bacterium from the human oral cavity.

It is suggested that strain DSM 24645(T) represents a novel species in a new genus, for which the name Stomatobaculum longum gen. nov., sp.

Akkermansia muciniphila gen. nov., sp. nov., a human intestinal mucin-degrading bacterium.

According to the data obtained in this work, strain MucT represents a novel bacterium belonging to a new genus in subdivision 1 of the Verrucomicrobia; the name Akkermansia muciniphila gen. nov., sp.

Phylogenetic and phenotypic evidence for the transfer of Eubacterium aerofaciens to the genus Collinsella as Collinsella aerofaciens gen. nov., comb. nov.

Based on a 16S rRNA sequence divergence of greater than 9% with Coriobacterium glomerans and the presence of a unique peptidoglycan type, a new genus, Collinsella, is proposed for Eubacterium aerofaciens, with one species, Coll insella aer ofaciens.

Phylogenetic relationships of the genera Acetobacterium and Eubacterium sensu stricto and reclassification of Eubacterium alactolyticum as Pseudoramibacter alactolyticus gen. nov., comb. nov.

The data indicate that Clostridium cluster XV consists of at least the following three genera: the genus Acetobacterium, the genus Eubacterium sensu stricto (comprising E. limosum, E. barkeri, and E. callanderi), and the genus Pseudoramibacter gen. nov., which is created for E. alactolyticum.

Isolation and characterization of two new homoacetogenic hydrogen-utilizing bacteria from the human intestinal tract that are closely related to Clostridium coccoides

Two gram-positive, strictly anoxic, coccoid- to rod-shaped strains of bacteria, Clostridium coccoides 1410 and C. coccoides 3110, were isolated from human feces on the typical homoacetogenic

The family Coriobacteriaceae: reclassification of Eubacterium exiguum (Poco et al. 1996) and Peptostreptococcus heliotrinreducens (Lanigan 1976) as Slackia exigua gen. nov., comb. nov. and Slackia heliotrinireducens gen. nov., comb. nov., and Eubacterium lentum (Prevot 1938) as Eggerthella lenta gen

Two new genera are proposed on the basis of phenotypic characteristics and 16S rRNA gene sequence comparisons: Slackia to include the bile-sensitive species Eubacterium exiguum and P. heliotrinreducens, and Eggerthella to include what is believed to be the biles-resistant Eubacteria lentum.

New Genus, Coprococcus, Twelve New Species, and Emended Descriptions of Four Previously Described Species of Bacteria from Human Feces

A new genus of anaerobic cocci, Coprococcus, and 12 new species ofAnaerobes, including CoprocOCcus eutactus, are described and proposed neotype strains for Streptococcus constellatus (Prevot) comb.

Quantification of Different Eubacteriumspp. in Human Fecal Samples with Species-Specific 16S rRNA-Targeted Oligonucleotide Probes

Species-specific 16S rRNA-targeted, Cy3 (indocarbocyanine)-labeled oligonucleotide probes were designed and validated to quantify different Eubacterium species in human fecal samples and showed that whole-cell in situ hybridization with species-specific probes is a valuable tool for the enumeration of Eubacteria species in feces.

Quantitative fluorescence in situ hybridization of Bifidobacterium spp. with genus-specific 16S rRNA-targeted probes and its application in fecal samples

Since the total culturable counts were only a fraction of the total microscopic counts, the contribution of bifidobacteria to the total intestinal microflora was overestimated by almost 10-fold when cultural methods were used as the sole method for enumeration.

The Roll-Tube Method for Cultivation of Strict Anaerobes

Habitats devoid of oxygen include the interior of the alimentary tracts of most mammals, the lower portions of many oligotrophic lakes, the sediment underlying bodies of water, and water logged soils, which are chiefly responsible for the lack of O2.

Temperature Gradient Gel Electrophoresis Analysis of 16S rRNA from Human Fecal Samples Reveals Stable and Host-Specific Communities of Active Bacteria

The results indicate that the combination of cloning and TGGE analysis of 16S rDNA amplicons is a reliable approach to monitoring different microbial communities in feces.
