Abstract

To assess the status of avian leukosis virus subgroup J (ALV-J) infection in passerine birds in China, 365 passerine birds collected from northeast China from 2011 to 2013 were tested, and two ALV-J strains were isolated from yellow-browed warbler and marsh tit. The 3'untranslated regions (3'UTRs) of the two strains were amplified, cloned, and sequenced, with the results showing that the 3'UTRs of the two strains contained multiple mutations and deletions, which are similar to viral strains isolated from Chinese layer chickens. These results demonstrate the presence of ALV-J in passerine birds and reveal the molecular characteristics of the 3'UTRs of ALV-J from passerine birds.
