  • 😷 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 Taiwan has been imported on 2024-11-03. The full classification is: risk group = 1, note = "P650 = v". — 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.
  • 🧍 According to Shipunov (2011), this name is a hemihomonym. Publication: Shipunov A. The problem of hemihomonyms and the on-line hemihomonyms database (HHDB). Bionomina 2011; 4:65-72.
  • 🧍 Later homonym of the algal genus name, Micromonas I. Manton and M. Parke 1960; the name is illegitimate because of this precedence. Publication: Oren A. On names of genera of prokaryotes that are later homonyms of generic names with standing in the zoological or the botanical nomenclature. Proposal of Neomegalonema gen. nov. and Neomegalonema perideroedes comb. nov. as replacements for the prokaryotic generic name Meganema and the species name Meganema perideroedes. Int J Syst Evol Microbiol 2017; 67:4276-4278.
  • 🧍 The name Micromonas Murdoch and Shah 2000 is illegitimate because of precedence of the algal genus name, Micromonas I. Manton and M. Parke 1960 [Rule 51b(4)]. Consequently, a new genus designation Parvimonas has been validly published by Tindall and Euzéby 2006. Publication: Tindall BJ, Euzeby JP. Proposal of Parvimonas gen. nov. and Quatrionicoccus gen. nov. as replacements for the illegitimate, prokaryotic, generic names Micromonas Murdoch and Shah 2000 and Quadricoccus Maszenan et al. 2002, respectively. Int J Syst Evol Microbiol 2006; 56:2711-2713.
  • 🧍 According to Rule 65 (2),the genus name Micromonas must be in the feminine gender, not in the masculine gender as cited in the paper by Murdoch and Shah 2000. — The name Micromonas Murdoch and Shah 2000 is illegitimate because of precedence of a microalga Micromonas I. Manton and M. Parke (Eukaryota; Viridiplantae; Chlorophyta; Prasinophyceae; Mamiellales; Mamiellaceae; Micromonas; Micromonas pusilla). See: Principle 2 and Rule 51b(4).
