Prophages in the infant gut are pervasively induced and may modulate the functionality of their hosts.

ABSTRACT: Gut microbiome (GM) composition and function is pivotal for human health and disease, of which the virome's importance is increasingly recognised. However, prophages and their induction patterns in the infant gut remain understudied. Here, we identified 10645 putative prophages in 662 metagenomes from 1-year-old children in the COPSAC2010 mother-child cohort and investigated their potential functions. No core provirome was found as the most prevalent vOTU was identified in only ~70% of the samples. The most dominant cluster of vOTUs in the cohort was related to Bacteroides phage Hanky p00', and it carried both diversity generating retroelements and genes involved in capsular polysaccharide synthesis. Paired analysis of viromes and metagenomes from the same samples revealed that most propha
