DK Microbe

Due to our latest update, search function can only accept a-z, A-Z and 0-9. Other special characters will be removed from search query.

Our team is working on fixing this issue. We will update the site once we resolve this issue.

What the DK Microbe Tool Can Do

Given a set of 17 base-pair digital karyotyping tags, the DK Microbe tool searches for exact matches to virtual tags in the genomes of 2565 bacterial and viral genomes.

You may query for matches to a small number of tags by entering the tags directly in a text box (multiple tags are separated by commas). Alternatively, longer lists of tags to be matched may be uploaded in a file. Note that microbial tags that are exact matches to human digital karyotyping tags have been removed from the set of virtual microbial tags.

For a description of the bacterial and viral digital karyotyping virtual tag sets, see the following:
