Here, we establish a large phage sequence database and use strain-resolved analyses to investigate DNA phage succession in infants throughout the first 3 years of life. Analysis of 819 fecal metagenomes collected from 28 full-term and 24 preterm infants and their mothers revealed that early-life phageome richness increases over time and reaches adult-like complexity by age 3. Approximately 9% of early phage colonizers, which are mostly maternally transmitted and infect Bacteroides, persist for 3 years and are more prevalent in full-term than in preterm infants. Although rare, phages with stop codon reassignment are more likely to persist than non-recoded phages and generally display an increase in in-frame reassigned stop codons over 3 years. Overall, maternal seeding, stop codon reassignment, host CRISPR-Cas locus prevalence, and diverse phage populations contribute to stable viral colonization.","journal":"Cell Host & Microbe","year":2023,"id":321790,"datarank":1.075231741744283,"base_score":3.784189633918261,"endowment":3.784189633918261,"self_citation_contribution":0.5676284450877392,"citation_network_contribution":0.5076032966565436,"self_endowment_contribution":0.5676284450877392,"citer_contribution":0.5076032966565436,"corpus_percentile":null,"corpus_rank":null,"citation_count":43,"citer_count":43,"citers_with_citation_signal":29,"citers_with_endowment":29,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9205,"is_data_producer":true,"deposit_databanks":{"BioProject":["PRJNA698986"],"SRA":["PRJNA698986"],"figshare":["10.6084/m9.figshare.24083232.v4"]},"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1011942,"name":"LinXing Chen","orcid":null,"position":1,"is_corresponding":false},{"id":275438,"name":"Adair L.
