Clostridium asparagiforme sp. nov., isolated from a human faecal sample.
PMID : 16337765 DOI : 10.1016/j.syapm.2005.11.001 DOI : 10.1016/j.syapm.2005.11.001
An obligatory anaerobic, Gram-positive, rod-shaped organism was isolated from faeces of a healthy human donor. It was characterized using biochemical, phenotypic and molecular taxonomic methods. The organism produced acetate, lactate, and ethanol as the major products of glucose fermentation. The G + C content was 53 mol%. Based on comparative 16S rRNA gene sequencing, the unidentified bacterium is a member of the Clostridium subphylum of the Gram-positive bacteria, and most closely related to species of the Clostridium coccoides cluster (rRNA cluster XIVa) [M.D. Collins et al., The phylogeny of the genus Clostridium: proposal of five new genera and eleven new species combinations, Int. J. Syst. Bacteriol. 44 (1994) 812-826]. Clostridium bolteae and Clostridium clostridioforme were identified as the most closely related described species. A 16S rRNA sequence divergence value of > 3% suggested that the isolate represents a new species. This was also supported by the gyrase-encoding gyrB gene sequences. Based on these findings, we propose the novel bacterium from human faeces to be classified as a new species, Clostridium asparagiforme. The type strain of C. asparagiforme is N6 (DSM 15981 and CCUG 48471).

Validation List no. 117. List of new names and new combinations previously effectively, but not validly, published.
PMID : 17766848 DOI : 10.1099/ijs.0.65495-0
The purpose of this announcement is to effect the valid publication of the following effectively published new names and new combinations under the procedure described in the Bacteriological Code (1990 Revision). Authors and other individuals wishing to have new names and/or combinations included in future lists should send three copies of the pertinent reprint or photocopies thereof, or an electronic copy of the published paper, to the IJSEM Editorial Office for confirmation that all of the other requirements for valid publication have been met. It is also a requirement of IJSEM and the ICSP that authors of new species, new subspecies and new combinations provide evidence that types are deposited in two recognized culture collections in two different countries (i.e. documents certifying deposition and availability of type strains). It should be noted that the date of valid publication of these new names and combinations is the date of publication of this list, not the date of the original publication of the names and combinations. The authors of the new names and combinations are as given below, and these authors' names will be included in the author index of the present issue and in the volume author index. Inclusion of a name on these lists validates the publication of the name and thereby makes it available in bacteriological nomenclature. The inclusion of a name on this list is not to be construed as taxonomic acceptance of the taxon to which the name is applied. Indeed, some of these names may, in time, be shown to be synonyms, or the organisms may be transferred to another genus, thus necessitating the creation of a new combination.
