Accurate identification for pathogenic bacterium is an essential element in the clinical microbiology laboratory. We studied molecular analysis involving the identification of Chyseobacterium indologenes and evaluated the seventeen isolates in Korea with the 16S rRNA gene of the ribosome to estimate phylogenetic relationships within the genus Chyseobacterium in GenBank. The aligned data sets for C. indologenes were 1,176 nucleotides. Sequence variation within the C. indologenes was mostly due to nucleotide substitutions. Korean C. indologenes isolates were not strikingly different from the same species found in the other countries. However, the rates of base substitution in Korean C. indologenes isolates were higher than those of other C. indologenes isolates in GenBank. C. indologenes was placed as a sister species to C. isbiliense, C. hominis, C. hispanicum, C. molle, C. hungaricum, and C. pallidum.
