| phylogenetic analysis using e2 gene of classical swine fever virus reveals a new subgenotype in china. | outbreaks of classical swine fever (csf) have caused serious economic consequences in china. phylogenetic analysis based on full-length e2 gene sequences showed that five classical swine fever virus (csfv) isolates collected from hunan province in 2011 and 2012, together with seven other isolates from neighboring provinces, guangdong (5) and guangxi (2), could be classified as a new subgenotype 2.1c, which may have been endemic in the south of china for at least fourteen years. subgenotype 2.1c ... | 2013 | 23608662 |
| phylogenetic analysis of the e2 gene of classical swine fever virus from the guangxi province of southern china. | in this study, suspected classical swine fever (csf) samples from the guangxi province of china were obtained from pigs with acute csf, aborted fetuses, newborn pigs that died at 1-2 days of age, tonsils of healthy pigs, and leukocytes of immunized sows during 2001-2009. about 92 of 775 samples were found to be positive by rt-pcr, and 41 isolates were obtained. phylogenetic analysis was performed on the 31 isolates by sequencing the e2 gene, and the isolates were found to cluster into two groups ... | 2011 | 21287256 |
| genetic diversity of subgenotype 2.1 isolates of classical swine fever virus. | as the causative agent of classical swine fever, the economically devastating swine disease worldwide, classical swine fever virus (csfv) is currently classified into the 11 subgenotypes, of which subgenotype 2.1 is distributed worldwide and showing more genetic diversity than other subgenotypes. prior to this report, subgenotype 2.1 was divided into three sub-subgenotypes (2.1a-2.1c). to further analyze the genetic diversity of csfv isolates in china, 39 csfv isolates collected between 2004 and ... | 2016 | 27085291 |
