  • 🧍 The name Pirella staleyi is illegitimate because of precedence of the fungal genus Pirella Bainier 1883 [Rule 51b(4)]. Consequently, a new species designation Pirellula staleyi (Schlesner and Hirsch 1984) Schlesner and Hirsch 1987, has been proposed by Schlesner and Hirsch 1987. Publication: Schlesner H, Hirsch P. Rejection of the genus name Pirella for pear-shaped budding bacteria and proposal to create the genus Pirellula gen. nov. Int. J. Syst. Bacteriol. 1987; 37:441. 🇩🇪
  • 🧍 The strain ATCC 27377 DSM 6068 was previously the type strain of Pasteuria ramosa Metchnikoff 1888 (Approved Lists 1980). Publication: Metchnikoff E. Pasteuria ramosa un représentant des bactéries à division longitudinale. Annales de l'Institut Pasteur (Paris) 1888; 2:165-170.
