The name Escherichia v'ulneris sp. nov. (formerly called Alma group 1 and Enteric group 1 by the Centers for Disease Control and API group 2 by Analytab Products, Inc.) is proposed for a group of isolates from the United States and Canada, 74% of which were from human wounds. E. v'uilneris is a gram-negative, oxidase-negative, fermentative, motile rod with the characteristics of the family Enterobacteriaceae. Biochemical reactions characteristic of 61 E. illtneris strains were positive tests for methyl red, malonate, and lysine decarboxylase; a delayed positive test for arginine dihydrolase; acid production from D-mannitol, Larabinose, raffinose, L-rhamnose, D-xylose, trehalose, cellobiose, and melibiose; negative tests for Voges-Proskauer, indole, urea, H,S, citrate, ornithine decarboxylase, phenylalanine deaminase, and DNase; and no acid from dulcitol, adonitol, myo-inositol, and D-sorbitol. Two-thirds of the strains produced yellow pigment. Most strains gave negative or delayed positive reactions in tests for lactose, sucrose, and KCN. The E. vulneris strains tested were resistant to

There are seven names on the Approved Lists of Bacterial Names that have been treated as partial or total synonyms for strains belonging to the Enterohucter agglomerans-Herbicola group of Erwiniu species complex. A total of 124 strains belonging to this complex, isolated mainly from plant and human sources, were studied by deoxyribonucleic acid relatedness and by a variety of biochemical tests. Ninety of these strains fell into 13 deoxyribonucleic acid hybridization groups (2 to 13 strains per group), and the remaining 34 strains did not fit into any hybridization group. Nine of the hybridization groups could be separated biochemically, whereas four hybridization groups could not. Our results point out the inadequacy of the classification schemes presently used for these organisms, the inadequacy of the present nomenclature, the extreme diversity of the strains presently classified in the Enterobacter agglomerans-Herbicola group of ErM*iniu species complex, and the need for additional, in-depth studies of these organisms.
