Most of the Malaysia, Thailand, and Vietnam VPAHPND strains were clustered together and closely related. ii. The Malaysia VPAHPND strains SAB6, SEA5, and SEB2 were highly close related. iii. SDA4 were more closely related to the VPAHPND strains from China (JPKU01.1) iv. Non- VPAHPND strains SDA1 were more closely related to the reference 3HP compared to the others. v. Non- VPAHPND strains SA2D2 were distinctly related to the VPAHPND strains Clinical strains Non-VPAHPND strains
