    Abstract

    Two clinical strains, NF 296 and NF 931, present in our collection, were identified biochemically as members of CDC group II-i. Determination of the 16S rRNA gene sequence revealed highest similarity with strains of Sphingobacterium mizutaii. Because these strains produced indole, whereas S. mizutaii has been described as indole-negative, we also investigated the type strain and a reference strain of S. mizutaii, LMG 8340T ( = CCUG 15907T) and LMG 8341 ( = CCUG 15908), and found both strains also to be positive for indole production. These data warrant inclusion of some of the CDC group II-i strains into S. mizutaii and emended descriptions of Sphingobacterium mizutaii as indole-production-positive and of the genus Sphingobacterium as variable for indole production.

    • The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of CDC group II-i strains LMG 8345 and LMG 8346 and S. mizutaii strains NF 931, LMG 8341, LMG 8340T and NF 296 are JF708885–JF708890, respectively.
