This was the first conference on spumaretroviruses to be held in the Southern Hemisphere and in the unique environment of the rainforest. New developments and current perspectives in FV research were presented. Highlights of the conference included the structural biology of the envelope protein (Env) and insights into its function and evolution, epidemiologic identification of Amazonian indigenous people with a high prevalence of simian FV (SFV) infections, investigations of virus biology and genomics using synthetic FV DNAs, studies of humoral immune response, and development and applications of SFV vectors. The last day of the meeting was a special tour of the Centro de Primatologia do Rio de Janeiro, located northeast of Rio de Janeiro amidst the protected rainforest, where New World primate hosts of spumaretroviruses are rescued and studied. Our report summarizes the meeting highlights and outcomes for future discussions.<\/jats:p>","DOI":"10.3390\/v17081071","type":"journal-article","created":{"date-parts":[[2025,8,1]],"date-time":"2025-08-01T06:37:47Z","timestamp":1754030267000},"page":"1071","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Thirteenth International Foamy Virus Conference\u2014Meeting Report"],"prefix":"10.3390","volume":"17","author":[{"given":"Arifa S.","family":"Khan","sequence":"first","affiliation":[{"name":"Laboratory of Retroviruses, Division of Viral Products, Office of Vaccines Research and Review, Center for Biologics Evaluation and Review, U.S. Food and Drug Administration, Silver Spring, MD 20993, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"L\u00f6chelt","sequence":"additional","affiliation":[{"name":"Research Topic Immunology, Infection and Cancer, Division Virus-Associated Carcinogenesis, German Cancer Research Center (DKFZ), 69120 Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9323-7837","authenticated-orcid":false,"given":"Florence","family":"Buseyne","sequence":"additional","affiliation":[{"name":"Institut Pasteur, Unit\u00e9 d\u2019Epid\u00e9miologie et Physiopathologie des Virus Oncog\u00e8nes, Universit\u00e9 Paris Cit\u00e9, 75015 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4453-7777","authenticated-orcid":false,"given":"Ottmar","family":"Herchenr\u00f6der","sequence":"additional","affiliation":[{"name":"Institute of Experimental Gene Therapy and Cancer Research, Rostock University Medical Center, 18057 Rostock, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0320-4223","authenticated-orcid":false,"given":"Dirk","family":"Lindemann","sequence":"additional","affiliation":[{"name":"Institute of Medical Microbiology and Virology, Faculty of Medicine, Technische Universit\u00e4t Dresden, 01307 Dresden, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4591-8731","authenticated-orcid":false,"given":"William M.","family":"Switzer","sequence":"additional","affiliation":[{"name":"Laboratory Branch, Division of HIV\/AIDS Prevention, National Center for HIV, Viral Hepatitis, STD, and TB Prevention, Centers for Disease Control and Prevention, Atlanta, GA 30329, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3372-1552","authenticated-orcid":false,"given":"Andr\u00e9 F.
