Molecular Characterization of Three Recombinant Isolates of Avian Leukosis Virus Obtained from Contaminated Marek's Disease Vaccines
1 Jun 2008
Abstract excerpt
Three natural recombinant avian leukosis viruses (ALV; PDRC-1039, PDRC-3246, and PDRC-3249) expressing a subgroup A gp85 envelope protein and containing long terminal repeats (LTR) of endogenous ALV-E viruses were isolated from contaminated commercial Marek's disease vaccines, cloned, and completely sequenced. Their full genomes were analyzed and compared with representative strains of ALV. The proviral DNA of...
