  • The type strain 25 = ATCC 33596 of Capnocytophaga ochracea Leadbetter et al. 1982, sp. nov. has 77% DNA homology with the type strain ATCC 27872 of Bacteroides ochraceus (Prévot et al. 1956) Holdeman and Moore 1972 (Approved Lists 1980). Therefore, Capnocytophaga ochracea should be a new combination, Capnocytophaga ochracea (Prévot et al. 1956) Leadbetter et al. 1982 and the type strain should be ATCC 27872 [3].
