| molecular characteristics and evolutionary analysis of field marek's disease virus prevalent in vaccinated chicken flocks in recent years in china. | marek's disease is a highly contagious, oncogenic, and immunosuppressive avian viral disease. surveillance of newly registered marek's disease virus (mdv) isolates is meaningful for revealing the potential factors involved in increased virulence. presently, we have focused on the molecular characteristics of all available mdvs from china, including 17 new henan isolates. based on meq, ge, and gi genes, we found that most chinese isolates contain conserved amino acid point mutations in meq, such ... | 2013 | 23813248 |
