Notes:
- ⏲ According to Genersch et al. (2006), this species is a later heterotypic synonym of Bacillus larvae White 1906 (Approved Lists 1980). Publication: Genersch E, Forsgren E, Pentikainen J, Ashiralieva A, Rauch S, Kilwinski J, Fries I. Reclassification of Paenibacillus larvae subsp. pulvifaciens and Paenibacillus larvae subsp. larvae as Paenibacillus larvae without subspecies differentiation.

- ❗ Bacillus pulvifaciens 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 Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 2, note = "PI". — The risk group for Germany has been imported on 2023-10-29. 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 7 times in PubMed until 2025-06-04.
- 🙅 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 the species itself.
- 🧍 A polyphasic taxonomic study of the two subspecies of Paenibacillus larvae, Paenibacillus larvae subsp. larvae and Paenibacillus larvae subsp. pulvifaciens, supported the reclassification of both subspecies into one species, Paenibacillus larvae, without subspecies classification.
