The salivary virome during childhood dental caries.

ABSTRACT: While many studies have examined the bacterial taxa associated with dental caries, the most common chronic infectious disease, little is known about the caries-associated virome. In this study, the salivary viromes of 21 children with severe caries (>2 dentin lesions) and 23 children with healthy dentition were examined. A total of 2,485 viral metagenome-assembled genomes (vMAGs) were identified, binned, and quantified from the metagenomic assemblies. These vMAGs were mostly phages and represented 1,865 unique species-level viral operational taxonomic units (vOTUs), of which 478 appear to be novel. The metagenomes were also queried for all 3,858 unique species-level vOTUs of DNA viruses with a human host on NCBI Virus; however, all but Human betaherpesvirus 7 were at very low abunda
