title: Bordetella trematum sp. nov., isolated from wounds and ear infections in humans, and reassessment of Alcaligenes denitrificans Rüger and Tan 1983.
abstract: Ten strains recognized on the basis of a computer-assisted numerical comparison of whole-cell protein patterns as members of a novel species belonging to the family Alcaligenaceae were examined by using an integrated phenotypic and genotypic approach. This species, for which we propose the name Bordetella trematum sp. nov., was more closely related to the type species of the genus Bordetella (Bordetella pertussis) than to the type species of the genus Alcaligenes (Alcaligenes faecalis) and had the general characteristics of members of this family (i.e., a DNA base ratio in the range from 57 to 70 mol%, a fatty acid profile characterized by high percentages of 16:0, 17:0 cyclo, and 14:0 3OH, nonsaccharolytic metabolism, and several classical biochemical characteristics, including aerobic and microaerobic growth, catalase activity, assimilation of citrate, an absence of anaerobic growth, and an absence of acetylmethylcarbinol and indole production, gelatin liquefaction, and esculin hydrolysis). A reevaluation of the criteria used to classify Alcaligenes denitrificans Rüger and Tan 1983 and Achromobacter xylosoxidans Yabuuchi and Ohyama 1971 as subspecies of Alcaligenes xylosoxidans and additional evidence provided in recent studies revealed that, consistent with present standards, it is appropriate to consider these two taxa distinct species of the genus Alcaligenes.
