Abstract:

【Objective】To explore the epidemiological characteristics and genetic variation of PRRSV in Hainan【Methods】Samples were collected from Haikou and surrounding areas.The PRRSV strain HNHK3-2021 was isolated, and the NSP2 genes, as well as the ORF5 and ORF7 gene sequences, were determined.Sequence alignment analysis was conducted using Lasergene 7.1, and genetic evolution analysis was performed using MEGA-X.【Results】The PRRSV HNHK3-2021 strain isolated was found to be of American origin with high nucleotide similarity to EF112447 HEB1, EU109503 GD, and EU624117 XH-GD ORF5 and ORF7 (99.2%~99.3% and 99.5%~100%, respectively).The derived amino acid similarity was 99%~99.5% and 100%.The nucleotide similarities of ORF5 and ORF7 of PRRSV HNHK3-2021 strain and EU864232 SHB, AY262352_HB-2(sh)2002, AY656990 Abst-1, AY032626 CH-1a, EU807840 CH-1R were found to be 87.1% -96.4% and 91.4%-97.3%, respectively.Similarly, the similarity of amino acids was 86.6%-93% and 91.9%-97.6%.The nucleotide similarities of ORF5 and ORF7 of PRRSV HNHK3-2021 strain and JN654459 NADC30, KP860909 FJZ03, MH068878 SD17-38, AY881994 FJ-1 were found to be 85.4%-87.1% and 89%-91.4%.The similarity of amino acids was 86.1%-87.1% and 89.5%-91.9%.【Conclusion】The PRRSV HNHK3-2021 strain and EU624117 XH-GD have the closest genetic distance.
