  Notes:
  - 🧍 Bacillus simplex (ex Meyer and Gottheil 1901) Priest et al. 1989 emend. Heyrman et al. 2005 also encompasses strains belonging to "Bacillus maroccanus" Delaporte and Sasson 1967, strains belonging to "Bacillus carotarum" Koch 1888, and the strain LMG 18508 = NCIMB 8796 of "Bacillus macroides".

Notes:
- ❗ Bacillus simplex 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 Bacillus.
- 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Animal classification RG: 1 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 1". — The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 1. — The risk group for Germany has been imported on 2026-08-13. The full classification is: risk group = 1. — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
- 🎓 Name mentioned 88 times in PubMed until 2026-06-11.
- 🙅 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as a synonym of the name to be applied to this species. The name is on LoRN because of the recorded risk group of other species in the genus.
- 🧍 In the effective publication by Priest et al. 1988, this name is cited as Bacillus simplex (ex Gottheil 1901) Priest et al. 1989. However, according to the Index Bergeyana, the synonym is "Bacillus simplex" Meyer and Gottheil 1901 in Gottheil 1901. Publication: Buchanan RE, Holt JG, Lessel Jr. EF. Index Bergeyana. The Williams & Wilkins Co., Baltimore, 1966.
