Notes:
- 🚋 The type species of this genus has alternatively been placed in the genus Escherichia Castellani and Chalmers 1919 (Approved Lists 1980). Publication: Leclerc H. [Biochemical study of pigmented Enterobacteriaceae]. Ann Inst Pasteur (Paris) 1962; 102:726-741.
- 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Leclerica"; "Leclericia"; "Ledercia".
- 🎰 The BRCs most frequently used for deposits in this group are: LMG: 3; JCM: 2; CCUG: 1; MCC: 1; ATCC: 1; CIP: 1; HAMBI: 1; DSM: 1; NCTC: 1; NBRC: 1.
- 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 2, note = "Animal classification RG: 1 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 2". — 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.
- 🧍 Pittman et al. (1991) suggested the abbreviation "LCLC" for this genus name but this does not appear to be of practical relevance any longer. Publication: Pittman KF, Walczak CA, Lock CM.
