title: Isolates belonging to CDC group II-i belong predominantly to Sphingobacterium mizutaii Yabuuchi et al. 1983: emended descriptions of S. mizutaii and of the genus Sphingobacterium.
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 8340(T) (=CCUG 15907(T)) 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.
