Phylogenetic tree based on whole-genome sequences of ASFV from a study of vaccine-like ASFV strain in domestic pigs, Thailand, 2024. Maximum-likelihood method and general time reversible model used in analyzing phylogenetic trees in MEGA 11 software (https://www.megasoftware.net). Red triangles indicate samples from this study; black circles indicate first ASFV strain in Thailand (TH1_22/CR), Georgia.2007/1, and ASFV-GUS-Vietnam. Genotypes are shown at right. Bootstrap analysis performed with 1,000 replicates; only bootstrap values >80 are shown. GenBank accessio numbers are provided for reference isolates. ASFV, African swine fever virus; GUS, GusA gene.
