- 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Euzeby JP. Notification list. Notification that new names and new combinations have appeared in volume 55, part 1 of the IJSEM. Int J Syst Evol Microbiol 2005; 55:987-991.
- ❗ Salmonella typhi 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 Salmonella.
