- Abstract
A novel Gram-negative, capnophilic, fusiform bacterium, designated strain ChDC OS43T, was isolated from a human refractory periapical abscess in the left mandibular second molar and was characterized by polyphasic taxonomic analysis. The 16S rRNA gene sequence revealed that the strain belongs to the genus <italic>Capnocytophaga</italic>, as it showed sequence similarities to <italic>Capnocytophaga ochracea</italic> ATCC 27872T (96.30%) and <italic>C. sputigena</italic> ATCC 33612T (96.16%). The prevalent fatty acids of strain ChDC OS43T were isoC15:0 (57.54%), C16:0 (5.93%), C16:0 3OH (5.72%), and C18:1<italic>cis</italic> 9 (4.41%). The complete genome of strain ChDC OS43T was 3,412,686 bp, and the G+C content was 38.2 mol%. The average nucleotide identity (ANI) value between strain ChDC OS43T and <italic>C. ochracea</italic> ATCC 27872T or <italic>C. sputigena</italic> ATCC 33612T was >92.01%. The genome-to-genome distance (GGD) value between strain ChDC OS43T and <italic>C. ochracea</italic> ATCC 27872T or <italic>C. sputigena</italic> ATCC 33612T was 32.0 and 45.7%, respectively. Based on the results of phenotypic, chemotaxonomic, and phylogenetic analysis, strain ChDC OS43T (= KCOM 1579T = KCTC 5562T = KCCM 42841T = JCM 32133T) should be classified as the type strain of a novel species of genus <italic>Capnocytophaga</italic>, for which the name <italic>Capnocytophaga endodontalis</italic> sp. nov. is proposed.
