Genetic mutations of avian leukosis virus subgroup J strains extended their host range

Journal of General Virology, 2014
The genetic diversity of avian leukosis virus subgroup J (ALV-J) is determined not only by the env gene, but also by its 3′ UTR and 3′ LTR. They all play important roles in extending the host range and tumour development. In the present study, one ALV-J strain (ZB110604-6) from Black-Bone Silky Fowl (BSF) and three ALV-J strains (ZB110604-3/4/5) from ...

Detection of subgroup J avian leukosis virus infection in Australian meat‐type chickens

Australian Veterinary Journal, 2004
Objective To determine the extent of avian leukosis virus subgroup J (ALV‐J) infection in Australian broiler breeder flocks, using virus isolation and molecular biological detection. Any resultant ALV‐J viral isolates to be characterised by neutralisation cross testing in order to determine antigenic relationships to overseas isolates of ALV‐J.

A novel multi-variant epitope ensemble vaccine against avian leukosis virus subgroup J

Vaccine, 2017
The hypervariable antigenicity and immunosuppressive features of avian leukosis virus subgroup J (ALV-J) has led to great challenges to develop effective vaccines. Epitope vaccine will be a perspective trend. Previously, we identified a variant antigenic neutralizing epitope in hypervariable region 1 (hr1) of ALV-J, N-LRDFIA/E/TKWKS/GDDL/HLIRPYVNQS-C ...

Body Weight Suppression in Broilers Naturally Infected with Avian Leukosis Virus Subgroup J

Avian Diseases, 1999
Broiler progeny were hatched from avian leukosis virus (ALV)-negative and ALV subgroup J (ALV-J)-positive breeders. ALV-J infection in progeny was identified by p27 antigen capture enzyme-linked immunosorbent assay and reverse transcriptase-polymerase chain reaction specific for ALV-J performed on serum or plasma samples obtained at hatch.

Occurrence of avian leukosis virus subgroup J in commercial layer flocks in China

Avian Pathology, 2004
Mortality from myeloid leukosis was observed in commercial layers from 12 farms in northern China. Affected chickens were extremely thin and dehydrated, bleeding occurred in feather follicles and claws, combs were pale and anaemic, phalanges were swollen, and many yellowish-white tumours were seen on the visceral surface of the sternum.

Generation and evaluation of avian leukosis virus subgroup J envelope glycoprotein recombinant pseudovirions

Journal of Virological Methods, 2014
Retroviral and lentiviral vector pseudotypes (based on human immunodeficiency virus type 1, HIV-1) have been used for stable and safe gene transfer because of their broad host ranges and high mechanical strength. In the present study, a recombinant avian leukosis virus subgroup J (ALV-J) polypeptide pseudotyped with lentivirus membrane glycoproteins ...

High Virus Titer in Feather Pulp of Chickens Infected with Subgroup J Avian Leukosis Virus

Avian Diseases, 2002
Subgroup J avian leukosis viruses (ALVs), which are a recombinant virus between exogenous and endogenous ALVs, can spread by either vertical or horizontal transmission. Exogenous and endogenous ALVs can be detected in feather pulp. In this study, virus titers in feather pulp of chickens infected with subgroup J ALV were compared with those of plasma ...

Determination of Subgroup J Avian Leukosis Virus by Surface Plasmon Resonance Immunosensor

Analytical Letters, 2014
Two novel Fourier transform-surface plasmon resonance immunosensors were fabricated for the determination of the subgroup J avian leukosis virus. The immunosensors were based on a functionalized gold substrate and immobilized gold–silver nanoparticles.
