Valid publication of the names Caecibacterium and Caecibacterium sporoformans.

Descriptions of the genus Caecibacterium and its proposed type species Caecibacterium sporoformans were published in the IJSEM by Onrust et al. (Int J Syst Evol Microbiol 2017;67:4589-4594). The type strain was deposited as LMG 27730 and DSM 26959. DSM 26959 is a patent strain, and therefore the names were effectively, but not validly, published based on Rule 30(4) of the International Code of Nomenclature of Prokaryotes. The type strain of C. sporoformans is now available from the Deutsche Sammlung von Mikroorganismen und Zellkulturen as DSM 103070 and no restrictions have been placed on its distribution. We here present new descriptions of the genus and its type species so that the names can be validly published.
