| genomic comparison between attenuated chinese equine infectious anemia virus vaccine strains and their parental virulent strains. | a lentiviral vaccine, live attenuated equine infectious anemia virus (eiav) vaccine, was developed in the 1970s, and this has made tremendous contributions to the control of equine infectious anemia (eia) in china. four key virus strains were generated during the attenuation of the eiav vaccine: the original liao-ning strain (eiav(ln40)), a donkey-adapted virulent strain (eiav(dv117)), a donkey-leukocyte-attenuated vaccine strain (eiav(dlv121)), and a fetal donkey dermal cell (fdd)-adapted vacci ... | 2010 | 21136127 |
