| Outline of Final Research Achievements |
Multilocus sequence analysis (MLSA) was performed on 107 species of Gram-negative anaerobic rods including the genus Bacteroides. The genes selected, dnaJ, gyrB, hsp60, recA, rpoB and 16S rRNA were amplified by direct PCR and then sequenced. For the genus Bacteroides, we defined species as a group of strains that share at least 97.5 % gene sequence similarity based on the fragments of five protein-coding housekeeping genes and 16S rRNA gene. Analyses of the concatenated sequences of all six genes revealed robust phylogenetic relationships among the species of Gram-negative anaerobic rods when compared with the single-gene trees.
