Studies with other enteric viruses have revealed that LPS and other lipid\/carbohydrate structures facilitate virus\u2013bacterial interactions, and it has also been shown that human noroviruses (HuNoVs) can interact with histo-blood group antigen (HBGA)-like compounds on the surface of bacterial cells. Based on these findings, this study hypothesized that carbohydrate-based compounds were the ligands that facilitated binding of both human and murine noroviruses (MNV) to bacteria. Using glycan microarrays, competitive inhibition assays, and a panel of bacterial mutants, the project assessed the influence of specific glycans on viral attachment to bacteria. Protein-based interactions were also examined. The results supported previous work which demonstrated that HuNoVs strongly bind HBGA-like glycans, while MNV displayed distinct binding to other glycans including aminoglycosides and fucosylated structures. Ultimately, this work demonstrates that HuNoVs have more limited binding requirements for bacterial attachment compared to MNV, and the MNV binding to bacteria may involve both specific structures as well as electrostatic interactions. Given the importance of commensal bacteria during viral infection, defining the molecular mechanisms that mediate virus\u2013bacteria interactions is critical for understanding infection dynamics and may be useful in the development of disease therapeutics and novel technologies for viral detection from food and environmental sources.<\/jats:p>","DOI":"10.3390\/v17081142","type":"journal-article","created":{"date-parts":[[2025,8,20]],"date-time":"2025-08-20T13:18:14Z","timestamp":1755695894000},"page":"1142","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Determining the Importance of Carbohydrate-Based Structures in Murine Norovirus Binding to Commensal Bacteria"],"prefix":"10.3390","volume":"17","author":[{"given":"Jasmine","family":"Madrigal","sequence":"first","affiliation":[{"name":"Department of Microbiology and Cell Science, IFAS, University of Florida, Gainesville, FL 32611, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Sullivan","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Cell Science, IFAS, University of Florida, Gainesville, FL 32611, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feba","family":"Mathew","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Cell Science, IFAS, University of Florida, Gainesville, FL 32611, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melanie","family":"Bland","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Cell Science, IFAS, University of Florida, Gainesville, FL 32611, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7093-2351","authenticated-orcid":false,"given":"Melissa","family":"Jones","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Cell Science, IFAS, University of Florida, Gainesville, FL 32611, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bartsch, S.M., Lopman, B.A., Ozawa, S., Hall, A.J., and Lee, B.Y.
