JF International Journal of Systematic and Evolutionary Microbiology, VO 35 IS 4 SP 443 OP 453 DO https://doi.org/10.1099/00207713-35-4-443 PB Microbiology Society, SN 1466-5034, AB The historical and present taxonomic and nomenclatural status of the following taxa were examined: “Vibrio terrigenus”Günther 1894, “Vibrio percolans”Mudd and Warren 1923, “Vibrio alcaligenes” Lehmann and Neumann 1927, “Lophomonas alcaligenes” Galarneault and Leifson 1956, “Comamonas percolans”Davis and Park 1962, “Comamonas terrigena” Hugh 1962, “Pseudomonas terrigena” Hugh 1965, “Vibrio cyclosites” Gray and Thornton 1928, “Vibrio neocistes” Gray and Thornton 1928, “Vibrio cuneatus” Gray and Thornton 1928, and “Comamonas compransoris”Nozhevnikova and Zavarzin 1974. Most of these organisms have been misnamed. Deoxyribonucleic acid-ribosomal ribonucleic acid hybridization experiments localized “C. terrigena” (“V. percolans”) NCIB 8193, “V. neocistes” NCIB 2582, and “V. cyclosites” NCIB 2581 on the Pseudomonas acidovorans ribosomal ribonucleic acid branch in the direct Vicinity of Pseudomonas testosteroni. Deoxyribonucleic acid-deoxyribonucleic acid hybridization experiments, serological studies, gel electropherograms of soluble proteins, and a numerical analysis of phenotypic features supported placement of these strains and clinical isolate CCUG 12940 in a single taxon, for which we propose revival of the name Comamonas terrigena Hugh 1962. The type strain is strain NCIB 8193 (= ATCC 8461 = LMG 1253 = CCUG 15327). C. terrigena is the type species of the genus Comamonas Davis and Park 1962 nom. rev. An extensive phenotypic description of C. terrigena is given, and this species can be differentiated from P . acidovorans and P . testosteroni.”Achromobacter cystinovorum” NCIB 4854 is misnamed and was found to be very closely related to P . acidovorans. “V. alcaligenes” NCTC 9239 was found to be misnamed and is closely related to Pseudomonas diminuta, which is itself inappropriately retained in the genus Pseudomonas. The classification of “V. cuneatus”NCIB 8194 as Pseudomonas fluorescens is confirmed. “C. compransoris” DSM 1231 and “V. cyclosites”ATCC 14635 (the so-called synonymous strain of “V. cyclosites” NCIB 2581) are definitely not members of C . terrigena. These two strains differ considerably from each other, as well as from all of the other strains investigated; their exact taxonomic position is unknown., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-35-4-443
