A pooled data set of Gram-negative eubacterial, mainly Vibrionaceae, 5S rRNA sequences from MacDonell and Colwell [15] and from Erdmann et al. [10] was processed by single, average, and complete linkage procedures, as generated by theclustan program suite [23]. The hierarchical structures produced broadly resembled those for the published data: the resolution of the new genusShewanella MacDonnell and Colwell 1985 [15] and an expanded definition forPhotobacterium are supported. The new phenon representingListonella [15] was not resolved, but the related speciesVibrio mimicus andV. cholerae were linked by one procedure. It is suggested that recognition of synonymy betweenPhotobacterium angustum andP. leiognathi and the incorporation ofV. anguillarum, V. damsela, andV. pelagius into the new genusListonella be held in abeyance pending supporting evidence. It is concluded that this widely available program produces analyses of 5S rRNA sequences of quality comparable to more specialized packages.
