Comment It has been known that about 800 species of oral bacteria inhabit the human oral cavity. Of them, 450 species have been cultured. The oral bacteria is the major causative agents of systemic diseases such as cardiovascular diseases as well as oral diseases such as periodontitis and dental caries. However, the causative bacterial species for oral diseases have been not known because the dental diseases are occurred by the multiple infection. In addition, the prevalence of the oral bacterial species is different by the geographic location of the host and individual. It is very important to obtain the oral bacteria from a rean population for pathogenesis studies related to oral infectious diseases. The purpose of this study is to obtain the oral clinical strains and their genetic resources, such as 16S rDNA, species-specific PCR or qPCR primers, and whole genome sequences, offer them to the researchers who work in dental science.
