3.2 | Phylogenetic analysis
All FMDV positive samples generated a single VP1 sequence apart from
SUD/7/2017 where a mixture of O and SAT 2 were recovered. The most
appropriate nucleotide substitution models for each serotype were found
to be the Tamura-Nei (TN-93) model, gamma distributed with invariant
sites (G+I) (type O and type SAT 2); and the Hasegawa-Kishino-Yano (HKY)
model, G+I (type A).
