  • 🙆 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this subspecies. The name is on LoRN because of the recorded risk group of other species in the genus.
  • 🧍 According to Ludwig et al. (2021), as "the type species of Lacticaseibacillus (L. casei subsp. casei) this subspecies needs to be reclassified within this genus, and perhaps as an independent species".
