Special topic: The scientific name of Faecalibacterium prausnitzii
               JCM 31915 has been changed.

The genus Faecalibacterium was established by Dr. Sylvia H. Duncan and
her colleagues in the United Kingdom in 2002 for the reclassification
of formerly misidentified strains of Fusobacterium prausnitzii ATCC
27768T and its reference strain ATCC 27766, along with two other
isolates (A2-165 and L2-6). Consequently, these strains have been
reclassified as Faecalibacterium prausnitzii (hereinafter F.
prausnitzii). Currently the genus Faecalibacterium is recognized as
one of the most important gut butyrate-producing bacteria for human
Since 2017, JCM has been distributing strain A2-165 JCM 31915 = DSM
17677). Since its launch, this strain has been used by many
researchers and boasts the third highest track record of distribution.
F. prausnitzii strain A2-165 is not a type strain, but it is a very
famous strain that is used by a large number of researchers at the
world level. Intraspecific diversity of F. prausnitzii has been
discussed for some time. A paper on the reclassification of
Faecalibacterium strains was published in the April issue 2022 of the
International Journal of Systematic and Evolutionary Microbiology
(IJSEM). Therefore, the scientific name of F. prausnitzii JCM 31915
(strain A2-165), which has been distributed by JCM, has been changed
to Faecalibacterium duncaniae JCM 31915T. The scientific name of this
strain is named after Dr. Sylvia H. Duncan, who founded the genus

Sakamoto et al. 2022. Genome-based, phenotypic and chemotaxonomic
classification of Faecalibacterium strains: proposal of three novel
species Faeca1libacterium duncaniae sp. nov., Faecalibacterium

Lists of JCM strains released
Lists of JCM strains have been released. The lists are available for
all prokaryotes (i.e., Bacteria and Archaea) and for some individual
groups, such as Archaea, Lactic acid bacteria, and Yeasts. Using the
lists, JCM strains could be concentrated based on taxonomic names of
higher ranks, medium numbers, growth temperatures, etc. The lists
will be helpful in selecting and ordering JCM strains.
