Since then, it has been reported in cases of keratoconjunctivitis and male urethritis. Three epidemiologically unrelated fatal cases of neonatal sepsis associated with infection by HAdV-D strains with a similar genetic makeup were documented in the United States between 2014 and 2020. Methods: Whole genome sequences were obtained for the isolated strains, and genomics analyses were conducted to compare them to phylogenetically related HAdV-D genomic sequences available in GenBank. Results: The three new US strains were indistinguishable by in silico restriction enzyme analysis. Their genome sequences were 99.9% identical to one another and to the prototype strain isolated in 2008 from a similar context of disease. The phylogenetic reconstruction revealed a highly supported clustering of all HAdV-D56 strains isolated in various countries since 1982. Our comparison to serologically intermediate strains 15\/H9 described in the literature indicated that HAdV-D56-like viruses have circulated worldwide since the late 1950s. Conclusion: As with other HAdV-D genotypes with the ability to infect ocular and genital mucosae, the risk of severe prenatal or perinatal HAdV-D56 infection must be considered.<\/jats:p>","DOI":"10.3390\/v13061105","type":"journal-article","created":{"date-parts":[[2021,6,9]],"date-time":"2021-06-09T22:18:29Z","timestamp":1623277109000},"page":"1105","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Fatal Neonatal Sepsis Associated with Human Adenovirus Type 56 Infection: Genomic Analysis of Three Recent Cases Detected in the United States"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7959-1445","authenticated-orcid":false,"given":"William R.","family":"Otto","sequence":"first","affiliation":[{"name":"Division of Infectious Diseases, Department of Pediatrics, The Children\u2019s Hospital of Philadelphia (CHOP), Philadelphia, PA 19104, USA"},{"name":"Center for Pediatric Clinical Effectiveness, CHOP, Philadelphia, PA 19104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6497-917X","authenticated-orcid":false,"given":"Daryl M.","family":"Lamson","sequence":"additional","affiliation":[{"name":"Wadsworth Center, New York State Department of Health (WC-NYSDOH), Albany, NY 12201, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2180-2120","authenticated-orcid":false,"given":"Gabriel","family":"Gonzalez","sequence":"additional","affiliation":[{"name":"National Virus Reference Laboratory (NVRL), University College Dublin, D04 V1W8 Dublin, Ireland"},{"name":"International Collaboration Unit, Research Center for Zoonosis Control, Hokkaido University, Sapporo 001-0020, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3900-379X","authenticated-orcid":false,"given":"Geoffrey A.","family":"Weinberg","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University of Rochester School of Medicine & Dentistry Rochester (UoR), Rochester, NY 14642, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicole D.","family":"Pecora","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, UoR, Rochester, NY 14642, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8224-4281","authenticated-orcid":false,"given":"Brian T.","family":"Fisher","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases, Department of Pediatrics, The Children\u2019s Hospital of Philadelphia (CHOP), Philadelphia, PA 19104, USA"},{"name":"Center for Pediatric Clinical Effectiveness, CHOP, Philadelphia, PA 19104, USA"},{"name":"Immune Dysregulation Program, CHOP, Philadelphia, PA 19104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kirsten","family":"St. George","sequence":"additional","affiliation":[{"name":"Wadsworth Center, New York State Department of Health (WC-NYSDOH), Albany, NY 12201, USA"},{"name":"Department of Biomedical Science, University at Albany, SUNY, Albany, NY 12222, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6499-9579","authenticated-orcid":false,"given":"Adriana E.","family":"Kajon","sequence":"additional","affiliation":[{"name":"Lovelace Biomedical Research Institute, Albuquerque, NM 87108, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,9]]},"reference":[{"key":"ref_1","first-page":"190","article-title":"Neonatal adenovirus pneumonia","volume":"113","author":"Green","year":"1989","journal-title":"Arch.
