GIB (Genome Information Broker) provides an integrated search of Bacteria, Archaea, Eukaryota complete genome sequences. Because the genome sequence data of Bacteroides fragilis YCH46 was released by Kitasato Institute for Life Sciences, we incorporated it to GIB, and now you can search those data.
