Abstract

Streptococcus salivarius DB-B5 was isolated from the supragingival plaque of a healthy female subject. The complete 2.3-Mb genome consists of one circular chromosome, two circular plasmids (including a megaplasmid), and one linear phage-like episome. The genome possesses two separate loci encoding bacteriocins.
