| molecular characterization and phylogenetic analysis of pseudorabies virus variants isolated from guangdong province of southern china during 2013-2014. | outbreaks of pseudorabies (pr) have occurred in southern china since late 2011, resulting in significant economic impacts on the swine industry. to identify the cause of pr outbreaks, especially among vaccinated pigs, 11 pseudorabies virus (prv) field strains were isolated from guangdong province during 2013-2014. their major viral genes (ge, tk, gi, pk, gd, 11k, and 28k) were analyzed in this study. insertions or deletions were observed in gd, ge, gi and pk genes compared with other prv isolate ... | 2016 | 26726029 |
| molecular epidemiology of pseudorabies virus in yunnan and the sequence analysis of its gd gene. | outbreaks of pseudorabies (prs) have occurred in yunnan, china, which caused significant economic loss. to determine the prevalence and origin of pr in yunnan, especially among vaccinated pigs, overall 791 samples of blood, tissue, semen, and sera were analyzed by serological methods, pcr, and sequence analysis of gd gene. detection with viral gi antibody or pcr showed that the yearly positive rates of pr virus (prv) in yunnan from 2010 to 2014 were 48.15, 21.26, 2.17, 5.22, and 0.35%, respectiv ... | 2017 | 28130636 |
