  • 🎓 Name mentioned 154 times in PubMed until 2026-06-11.
  • 🙆 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this species. The name is on LoRN because of the recorded risk group of the species itself.
  • 🧍 According to Bartlett et al. (2022), this species is an established human pathogen. Publication: Bartlett A, Padfield D, Lear L, Bendall R, Vos M. A comprehensive list of bacterial pathogens infecting humans. Microbiology (Reading) 2022; 168:0. 🇬🇧
  • 🧍 Plant pathogenic according to Bull et al. (2007). Publication: Bull CT, De Boer SH, Denny TP, Firrao G, Fischer Le Saux M, Saddler GS, Scortichini M, Stead DE, Takikawa Y. Comprehensive list of names of plant pathogenic bacteria, 1980-2007. Journal of Plant Pathology 2010; 92:551-592. 🇺🇸
  • 🧍 In the "Indexes of the Bacterial and Yeast Nomenclatural Changes", Moore and Moore [7, 8] write "Serratia liquefaciens (Grimes and Hennerty 1931) Bascomb et al. 1971 (AL) = Serratia proteamaculans (Paine and Stansfield 1919) Grimont et al. 1978 (AL)". However, Serratia liquefaciens and Serratia proteamaculans are distinct species. Publication: Holmes B.
