Dellaglio F, et al. Designation of ATCC 334 in place of ATCC 393 (NCDO 161) as the neotype strain of Lactobacillus casei subsp. casei and rejection of the name Lactobacillus paracasei (Collins et al., 1989), request for an opinion. Int. J. Syst. Bacteriol. 41: 340-342, 1991.

Judicial Commission of the International Committee on Systematics of Bacteria, The type strain of Lactobacillus casei is ATCC 393, ATCC 334 cannot serve as the type because it represents a different taxon, the name Lactobacillus paracasei and its subspecies names are not rejected and the revival of the name ?Lactobacillus zeae? contravenes Rules 51b (1) and (2) of the International Code of Nomenclature of Bacteria. Opinion 82. Int. J. Syst. Bacteriol. 58: 1764-1765, 2008. PubMed: 18599731
