  • kerstersia gyiorum gen nov sp nov a novel Alcaligenes faecalis like organism isolated from human clinical samples and reclassification of Alcaligenes denitrificans ruger and tan 1983 as achromobacter denitrificans comb nov
    International Journal of Systematic and Evolutionary Microbiology, 2003
    Co-Authors: Tom Coenye, Enevold Falsen, Marc Vancanneyt, Margo Cnockaert, Jean Swings, Peter Vandamme

    Abstract:

    A polyphasic taxonomic study was performed on nine isolates recovered from various human clinical samples. Phenotypically, these isolates resembled Alcaligenes faecalis. Whole-cell protein analysis distinguished two different species, and this was confirmed by DNA–DNA hybridizations. Cellular fatty acid analysis and 16S rDNA sequence analysis indicated that these isolates were related to the genera Alcaligenes, Bordetella, Achromobacter and Pigmentiphaga and belonged to the family Alcaligenaceae. On the basis of the results of this study, the organisms were classified in a novel genus, Kerstersia gen. nov. This genus comprises one species, Kerstersia gyiorum sp. nov. (type strain LMG 5906T=API 184-2-84T=CCUG 47000T), and several unnamed isolates. The DNA G+C content of members of the genus Kerstersia is between 61·5 and 62·9 mol%. On the basis of previously published DNA–DNA hybridization results and data from chemotaxonomic studies, it is proposed that Alcaligenes denitrificans Ruger and Tan 1983 be reclassified as Achromobacter denitrificans comb. nov.

  • bordetella trematum sp nov isolated from wounds and ear infections in humans and reassessment of Alcaligenes denitrificans ruger and tan 1983
    International Journal of Systematic and Evolutionary Microbiology, 1996
    Co-Authors: Peter Vandamme, Marc Heyndrickx, M Vancanneyt, Bart Hoste, Enevold Falsen, K. Kersters, K H Hinz

    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 30H, 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 Ruger 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.
