Recombination is one of the mechanisms that contribute to genetic diversity of FMDV and facilitate the generation of new viral lineages, or recombinant forms. While the general patterns of recombination in FMDV are well-known, the temporal dynamics of this process remain unexplored. This study systematically analyzed recombination across 1485 publicly available complete genome sequences of FMDV, collected from 1934 to 2024. In addition to the well-known general recombination pattern with hotspots on the borders of the genome region that encodes capsid proteins VP2-VP3-VP1, we identified serotype-specific recombination patterns. A significant temporal signal required to analyze temporal dynamics was found in serotypes A, Asia1, O, and SAT1 in the VP2-VP3-VP1 genome region. To assess the lifetimes of FMDV recombinant forms, we compared these time-scaled phylogenetic trees with phylogenies for other genomic regions exchanged by recombination events. The median lifetimes of FMDV recombinant forms ranged from 2 to 18 years, depending on the serotype and the nonstructural genomic region involved in recombination. These timescales are comparable to human (+)RNA viruses, such as enteroviruses and caliciviruses. In distinct serotypes, recombination could be more frequent on the 5\u2032 or 3\u2032 border of the capsid-encoding genome region, without a uniform pattern.<\/jats:p>","DOI":"10.3390\/v18020262","type":"journal-article","created":{"date-parts":[[2026,2,20]],"date-time":"2026-02-20T08:50:03Z","timestamp":1771577403000},"page":"262","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Temporal Dynamics of Recombination in Field Isolates of Foot-and-Mouth Disease Virus"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-0630-5286","authenticated-orcid":false,"given":"Mate","family":"Malichava","sequence":"first","affiliation":[{"name":"Martsinovsky Institute of Medical Parasitology, Tropical and Vector Borne Diseases, Sechenov First Moscow State Medical University, 119435 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7365-0352","authenticated-orcid":false,"given":"Alexander","family":"Lukashev","sequence":"additional","affiliation":[{"name":"Martsinovsky Institute of Medical Parasitology, Tropical and Vector Borne Diseases, Sechenov First Moscow State Medical University, 119435 Moscow, Russia"},{"name":"Research Institute for Systems Biology and Medicine, 117246 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2791-1835","authenticated-orcid":false,"given":"Yulia","family":"Aleshina","sequence":"additional","affiliation":[{"name":"Martsinovsky Institute of Medical Parasitology, Tropical and Vector Borne Diseases, Sechenov First Moscow State Medical University, 119435 Moscow, Russia"},{"name":"Faculty of Bioengineering and Bioinformatics, Lomonosov Moscow State University, 119234 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"465","DOI":"10.1128\/CMR.17.2.465-493.2004","article-title":"Foot-and-Mouth Disease","volume":"17","author":"Grubman","year":"2004","journal-title":"Clin.
