• Notes:
  • ⏲ According to Sakamoto and Ohkuma (2013), this species is a later heterotypic synonym of Porphyromonas crevioricanis Hirasawa and Takada 1994. Publication: Sakamoto M, Ohkuma M. Porphyromonas crevioricanis is an earlier heterotypic synonym of Porphyromonas cansulci and has priority. Int J Syst Evol Microbiol 2013; 63:454-457. 🇯🇵
  • ❗ Porphyromonas cansulci is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Porphyromonas.
