    Abstract


    The study was conducted to detect the presence of Porcine Cytomegalovirus (PCMV) in northern Vietnam pig farms.Total122 samples of pigs with respiratory pathological signs were screening by PCR and identified 59 positive samples with PCMV, accounting for 48.36%. Results of analyzing the nucleotide (nt) and amino acid (aa) of 3 PCMV virus strains collected in Thai Binh and Ha Noi showed that these strains were closely related to one other, sharing 99.22-100% at nt and 99.17-100% at aa, respectively. Phylogenetic tree analysis indicated that the PCMV strains belonged to two different branches, PCMV1.HN.2018 and PCMV3.HN.2019 strains were in the same branch as HN0601 strain isolated in China (accession number HQ686081), the 489 strain of Germany (AF268042), the OF-1 strain of Japan (AF268041) and the 55b strain of Spain (AF268040). Meanwhile, the PCMV2.TB.2019 strain was located in the same branch as the FJ01 strain isolated in China (MG696113). Thus, it can be concludedthat PCMV had circulated among pigs raised in northern Vietnam and had the same origin as the PCMV strains from China.
