A 205-Nucleotide Deletion in the 3′ Untranslated Region of Avian Leukosis Virus Subgroup J, Currently Emergent in China, Contributes to Its Pathogenicity
20 Sept 2012
Abstract excerpt
In the past 5 years, an atypical clinical outbreak of avian leukosis virus subgroup J (ALV-J), which contains a unique 205-nucleotide deletion in its 3' untranslated region (3'UTR), has become epidemic in chickens in China. To determine the role of the 205-nucleotide deletion in the pathogenicity of ALV-J, a pair of viruses were constructed and rescued. The first virus was an ALV-J Chinese isolate (designated...
