Abstract:
In this study, we compiled 84-year worth (1934-2017) of genomic and epidemiological data of foot-and-mouth disease virus (FMDV), and performed comprehensive analyses to determine its early origin and transmission route. We found that recombination is a key feature of FMDV, and that the genomic regions coding for structural and non-structural proteins have markedly different evolutionary histories, and evolve at different rates. Despite all of these differences, analyses of both structural and non-structural protein coding regions consistently suggested that the most recent common ancestor of FMDV could be dated back to the Middle Age, ~ 200 to 300 years earlier than previously thought. The ancestors of the Euro-Asiatic and SAT strains could be dated back to the mid-seventeenth century, and to the mid-fifteenth to mid-sixteenth century, respectively. Our results implicated Mediterranean counties as an early geographical origin of FMDV before spreading to Europe and subsequently to Asia and South America.
Insights
Foot-and-mouth disease virus (FMDV) originated earlier than previously thought, potentially in the Middle Ages. Genomic analysis reveals recombination is key to FMDV evolution and spread.
Area of Science:
- Veterinary Virology
- Molecular Evolution
- Epidemiology
Background:
- Foot-and-mouth disease virus (FMDV) poses a significant threat to livestock globally.
- Understanding FMDV's evolutionary history and origins is crucial for effective control strategies.
Purpose of the Study:
- To determine the early origin and transmission routes of FMDV.
- To analyze the evolutionary dynamics of FMDV using genomic and epidemiological data.
Main Methods:
- Compiled 84 years (1934-2017) of FMDV genomic and epidemiological data.
- Performed comprehensive phylogenetic and evolutionary analyses.
- Investigated recombination patterns and evolutionary rates of different genomic regions.
Main Results:
- Recombination is a significant factor in FMDV evolution.
- Structural and non-structural protein-coding regions exhibit distinct evolutionary histories and rates.
- The most recent common ancestor of FMDV dates to the Middle Ages, 200-300 years earlier than previously estimated.
- Ancestors of Euro-Asiatic and SAT strains originated in the mid-17th and mid-15th to mid-16th centuries, respectively.
- Mediterranean regions are implicated as an early geographical origin.
Conclusions:
- FMDV has a longer evolutionary history than previously recognized, originating in the Middle Ages.
- Distinct evolutionary pathways exist for different FMDV genomic components.
- Mediterranean areas likely served as an early hub for FMDV emergence and subsequent global dissemination.
