متن کاملComparison of Chinese field strains of avian leukosis subgroup J viruses with prototype strain HPRS-103 and United States strains.
Eight Chinese field strains of subgroup J avian leukosis viruses (ALV-J) were isolated from broilers or parent stocks during January 1999 to April 2001. One strain, SD9902, was an acute transforming virus, able to induce typical myelocytomatosis in 22-38 days after inoculation of 1-day-old meat-type chicks. The envelope protein and 3'-untranslated region (UTR) of the eight field strains were co...
متن کاملAntigenic variants of J subgroup avian leukosis virus: sequence analysis reveals multiple changes in the env gene.
HPRS-103, the prototype of avian leukosis virus (ALV) subgroup J, was isolated in 1989 from meat-type chickens from commercial flocks where it induces myelocytic myeloid leukosis (ML). The HPRS-103 env gene differs considerably from other ALV subgroups but shows high identity (75-97%) to env-like sequences of the different members of the EAV family of endogenous avian retroviruses. Recently, we...
متن کاملMultiple complex families of endogenous retroviruses are highly conserved in the genus Gallus.
We have analyzed the genome of the domestic chicken for the presence of genetic sequences related to the envelope protein-encoding genes of avian sarcoma/leukosis retroviruses to determine the organization, structure, potential functionality, and distribution of such sequences. We have previously identified in the genus Gallus an extensive group of endogenous avian retroviruses termed EAV-0. So...
متن کاملThe unique envelope gene of the subgroup J avian leukosis virus derives from ev/J proviruses, a novel family of avian endogenous viruses.
A new subgroup of avian leukosis virus (ALV), designated subgroup J, was identified recently. Viruses of this subgroup do not cross-interfere with viruses of the avian A, B, C, D, and E subgroups, are not neutralized by antisera raised against the other virus subgroups, and have a broader host range than the A to E subgroups. Sequence comparisons reveal that while the subgroup J envelope gene i...
