Popis: The name Yokenella regensburgei was validly published in June 1984 by Kosako, Sakazaki, and Yoshizaki (Jpn. J. Med. Sci. Biol. 37:117–124). Working independently, Hickman-Brenner, Huntley-Carter, Fanning, Brenner, and Farmer described Koserella trabulsii, which was validly published in January 1985 (J. Clin. Microbiol. 21:39–42). Both names gained standing in the nomenclature in April 1985 when they appeared in Validation List 17 (Int. J. Syst. Bacteriol. 35:223–225). Nine strains of Y. regensburgei and five of K. trabulsii were compared by deoxyribonucleic acid (DNA)-DNA hybridization and phenotype. By DNA-DNA hybridization (3H-labeled DNA, 65°C, nitrocellulose filter method), the type strain of Y. regensburgei was highly related (99%) to the type strain of K. trabulsii and highly related (78 to 100%) to the other strains of both species. The type strain of K. trabulsii was highly related (80%) to the type strain of Y. regensburgei and highly related (80 to 98%) to the other strains of both species. Y. regensburgei and K. trabulsii were almost identical phenotypically based on 68 phenotypic characteristics studied in Japan and 47 biochemical tests done in the United States. Based on their extremely close relationships by both molecular and phenotypic methods, we concluded that all 14 strains should be classified in a single species. The present Bacteriological Code does not indicate whether Y. regensburgei or K. trabulsii is the correct name for this species. Similarly, the recent proposal (April 1986) to emend the Bacteriological Code does not consider some of the unique features of this case. For these reasons, a Request for an Opinion will be made to the Judicial Commission to resolve this nomenclatural question. In the meantime, we recommend that both species names be written together with one name in parentheses.
