Schematic diagram from study of vaccine-like African swine fever virus strain in domestic pigs, Thailand, 2024, showing the deletion of the MGF gene region replaced by the β-GUS marker gene in the following strains: Georgia 2007/1, ASFV-GUS-Vietnam, and the 2 isolates from this study, TH1_24/RB and TH2_24/RB . Reference sequences obtained from GenBank. Deleted regions represented by dashed white arrows, intact genes by solid black arrows, and the inserted β-GUS gene by a yellow arrow. GUS, GusA gene; MGF, multigene family.
