Human infection with DTV can result in acute febrile illness followed by central nervous system complications, such as encephalitis and meningoencephalitis. Currently, there are mouse models established for investigating the pathogenesis and clinical outcomes of DTV that mimic human infections, but the strains of mice utilized are refractory to infection with B. burgdorferi s.l. Here, we describe the pathogenesis and clinical outcomes of DTV infection in C3H\/HeJ mice. Neurological clinical signs, mortality, and weight loss were observed in all DTV-infected mice during the investigation. Infected animals demonstrated consistent viral infection in their organs. Additionally, neuropathology of brain sections indicated the presence of meningoencephalitis throughout the brain. This data, along with the clinical outcomes for the mice, indicates successful infection and showcases the neuroinvasive nature of the virus. This is the first study to identify C3H\/HeJ mice as an appropriate model for DTV infection. As C3H\/HeJ mice are already an established model for B. burgdorferi s.l. infection, this model could serve as an ideal system for investigating disease progression and pathogenesis of co-infections.<\/jats:p>","DOI":"10.3390\/v17081092","type":"journal-article","created":{"date-parts":[[2025,8,8]],"date-time":"2025-08-08T08:09:35Z","timestamp":1754640575000},"page":"1092","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Development of a Deer Tick Virus Infection Model in C3H\/HeJ Mice to Mimic Human Clinical Outcomes"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4435-1027","authenticated-orcid":false,"given":"Dakota N.","family":"Paine","sequence":"first","affiliation":[{"name":"Department of Microbiology and Immunology, SUNY Upstate Medical University, Syracuse, NY 13210, USA"},{"name":"SUNY Center for Vector-Borne Diseases, SUNY Upstate Medical University, Syracuse, NY 13210, USA"},{"name":"Institute for Global Health and Translational Science, SUNY Upstate Medical University, Syracuse, NY 13210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2847-0982","authenticated-orcid":false,"given":"Erin S.","family":"Reynolds","sequence":"additional","affiliation":[{"name":"Center for Global Health, Department of Internal Medicine, University of New Mexico Health Sciences Center, Albuquerque, NM 87131, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7565-272X","authenticated-orcid":false,"given":"Charles E.","family":"Hart","sequence":"additional","affiliation":[{"name":"Defense Centers for Public Health\u2013Aberdeen, Defense Health Agency-Public Health, Edgewood, MD 21040, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-4546-5104","authenticated-orcid":false,"given":"Jessica","family":"Crooker","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, SUNY Upstate Medical University, Syracuse, NY 13210, USA"},{"name":"SUNY Center for Vector-Borne Diseases, SUNY Upstate Medical University, Syracuse, NY 13210, USA"},{"name":"Institute for Global Health and Translational Science, SUNY Upstate Medical University, Syracuse, NY 13210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4269-5993","authenticated-orcid":false,"given":"Saravanan","family":"Thangamani","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, SUNY Upstate Medical University, Syracuse, NY 13210, USA"},{"name":"SUNY Center for Vector-Borne Diseases, SUNY Upstate Medical University, Syracuse, NY 13210, USA"},{"name":"Institute for Global Health and Translational Science, SUNY Upstate Medical University, Syracuse, NY 13210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,7]]},"reference":[{"key":"ref_1","unstructured":"CDC (2022, October 26).
