We determined complete 1D gene sequences for one serotype A and seven additional serotype O Korean foot-and-mouth disease viruses (FMDV) and then analyzed them together with published sequences for 180 type A and 300 type O isolates from throughout the world using a Bayesian coalescent approach. Here, Korean serotype A virus was linked with those from Laos. Korean serotype O viruses were divided into three clades and were closely related to isolates from Japan, Thailand, the UK, France, Ireland… 
Evolutionary analysis of serotype A foot-and-mouth disease viruses circulating in Pakistan and Afghanistan during 2002-2009.
TLDR
Mapping of the amino acid changes between the capsid proteins of the A22/Iraq vaccine strain and the A-Iran05BAR-08 viruses onto the A 22/Iraq capsid structure identified candidate amino acid substitutions, exposed on the virus surface, which may explain this antigenic difference.
Evidence for multiple recombination events within foot-and-mouth disease viruses circulating in West Eurasia.
TLDR
It is concluded from the present study that dramatic changes in virus sequences can occur in the field through recombination between different FMDV genomes.
Foot-and-mouth disease virus serotype O phylodynamics: genetic variability associated with epidemiological factors in Pakistan.
TLDR
Viruses sequenced here provide the earliest reported isolate from the Pan Asia II(ANT-10) sublineage, which has caused several outbreaks in the Middle East and spread into Europe and Africa and is consistent with the frequent multi-species infection of this serotype O FMDV.
Evolutionary dynamics of foot-and-mouth disease virus O/ME-SA/Ind2001 lineage.
TLDR
The evolution of Ind 2001 lineage deviates from the strict molecular clock and a typical lineage evolutionary dynamics characterized by periodic emergence and re-emergence of Ind2001 and PanAsia lineage have been observed in respect of serotype O.
Genetic and antigenic relationship of foot-and-mouth disease virus serotype O isolates with the vaccine strain O1/BFS.
TLDR
The vaccine strain O1/BFS is likely to confer protection against 89% of the 45 FMDV/O isolates based on VNT and is still suitable for use in global FMD serotype O outbreak control.
Phylodynamics of foot-and-mouth disease virus O/PanAsia in Vietnam 2010–2014
TLDR
The phylogeny of FMDV O/PanAsia in Vietnam is investigated, reconstructing the virus’ ancestral host species (pig, cattle or buffalo), clinical stage (subclinical carrier or clinically affected) and geographical location, to provide novel insights to understand F MDV evolution and its association with viral spread within endemic countries.
Phylogenetic and evolutionary analysis of foot-and-mouth disease virus A/ASIA/Sea-97 lineage
TLDR
Phylogenetic and evolutionary analysis of Sea-97 using 224 VP1 sequences of FMDV A/ASIA during 1960 and 2018 revealed that Sea- 97 lineage can be classified into five groups (G1-G5), and substitution at antigenically important sites may affect the efficacy of the vaccine, suggesting the need for appropriate vaccine strains.
Phylodynamic reconstruction of O CATHAY topotype foot-and-mouth disease virus epidemics in the Philippines
TLDR
The analysis suggests that viruses from the O CATHAY topotype have been continually maintained within swine industries close to Hong Kong SAR, following the extinction of virus lineages from the Philippines and the reduced number of FMD cases in Taiwan.
Comparative study of codon substitution patterns in foot-and-mouth disease virus (serotype O)
TLDR
It is observed that FMDVs showed distinct RSCU patterns according to phylogenetic relationships in the same serotype (serotype O), and different EMC patterns among the 18 amino acids might be an important factor in determining the direction of evolution in FMDV.
Foot-and-mouth disease: Global status and Indian perspective
TLDR
The control programme, in operation since X Plan, has resulted in progressive and substantial reduction in occurrence of the disease and DIVA reactors/converters in vaccinated areas and the epidemiology of FMD in India and the world.

Molecular epidemiology of foot-and-mouth disease virus types A and O isolated in Argentina during the 2000-2002 epizootic.
TLDR
Comparison of the amino acid sequences with vaccine reference strains revealed differences at critical antigenic sites for emergent strains A/Arg/00 and A-Arg/01, leading to a change in the current vaccine formulation.
Molecular epidemiological investigation of foot-and-mouth disease virus in Korea in 2000.
TLDR
The result of phylogenetic analysis indicated that the Korean strains may have evolved from a common ancestor of the Pan Asia strains, and that at least 2 phylogenetically clustered variants within the same lineage were prevalent during the epidemic.
Genetic characterization and molecular epidemiology of foot-and-mouth disease viruses isolated from Afghanistan in 2003–2005
TLDR
This is the first published report of serotypes A in Afghanistan since 1975, therefore indicating the need for inclusion of serotype A in vaccine formulations that will be used to control disease outbreaks in this country.
Identification and antigenic site analysis of foot-and-mouth disease virus from pigs and cattle in Korea.
TLDR
Phylogenetic analysis with the some known strains from East Asian countries showed that the 4 Korean isolates in 2002 formed one distinct cluster, which different from clusters of Korean isolate in 2000, with in the same lineage of the ME-SA topotype strains.
The evolution of foot-and-mouth disease virus: impacts of recombination and selection.
TLDR
It is provided evidence that identification of recombinant sequences and recombination breakpoint patterns among and within serotypes are heavily dependent on the level of genetic diversity and convergent characters present in a particular data set as well as the methods used to detect recombination.
Comparison and Analysis of the Complete Nucleotide Sequence of Foot-and-Mouth Disease Viruses from Animals in Korea and Other PanAsia Strains
TLDR
Analysis of analytic data suggest that 2002 outbreaks in Korea is not re-occurred but re-introduced from nowhere.
Incursions of foot-and-mouth disease virus into Europe between 1985 and 2006.
TLDR
The present and the future potential sources of FMD infection need to be identified to best focus European efforts.
Subtyping of European foot-and-mouth disease virus strains by nucleotide sequence determination
TLDR
It is suggested that nucleotide sequence analysis should be used as a standard method of diagnosis, because when compared with other techniques it more clearly reveals the origin and course of epizootics and offers the possibility of preventing further outbreaks.
Genetic and antigenic analysis of two recently circulating genotypes of type A foot-and-mouth disease virus in India: evidence for positive selection in the capsid-coding genes
TLDR
Analysis of isolates of two recently circulating genotypes of type A foot-and-mouth disease virus (FMDV) from India found positive selection was detected at a number of amino acid positions behind a background of strong purifying selection, suggesting that FMDVs are under pressure from the immune system.

TLDR
The hypothesis that host selection acting on individual serotypes has been an important factor in the long-term evolution FMDV and needs to be considered for vaccine design is supported.
