A single chicken anemia virus protein induces apoptosis

Journal of Virology, 1994
Chicken anemia virus (CAV) causes cytopathogenic effects in chicken thymocytes and cultured transformed mononuclear cells via apoptosis. Early after infection of chicken mononuclear cells, the CAV-encoded protein VP3 exhibits a finely granular distribution within the nucleus. At a later stage after infection, VP3 forms aggregates.

Relationship of Torque Teno Virus to Chicken Anemia Virus

2009
This chapter examines the correlation between Torque teno virus (TTV) and chicken anemia virus (CAV). Each has a circular single-stranded (ss)DNA genome with every one of its known open reading frames (ORF) on its antigenomic strand. This structure is distinct from those of circoviruses. The genomic sizes of TTV and CAV are different, 3.8 kb and 2.3 kb,

Immunopathogenesis of chicken anemia virus infection

Developmental & Comparative Immunology, 2000
The immunopathogenesis of chicken anemia virus (CAV) infection is reviewed. The virus causes a disease in young chicks which is characterised by generalised lymphoid atrophy, increased mortality and severe anemia. The virus appears to target erythroid and lymphoid progenitor cells in the bone marrow and thymus respectively.

Genetic Characterization of Chicken Anemia Virus from Commercial Broiler Chickens in Alabama

Avian Diseases, 2001
Chicken anemia virus (CAV) isolates show extremely limited genetic variability worldwide. We determined the nucleotide sequence of an 823-nucleotide portion of the 2.3-kb CAV genome found in 10 liver and/or spleen specimens of Alabama 29-to-49-day-old commercial broiler chickens exhibiting lymphocyte depletion of the thymus submitted to the state ...

Immunopathologic Investigations with an Attenuated Chicken Anemia Virus in Day-Old Chickens

Avian Diseases, 2003
The immunopathologic effects induced by two attenuated chicken anemia virus (CAV) isolates, known as cloned isolate 34 (CI 34) and cloned revertant isolate 18 (CRI 18), that were derived from highly passaged pools of Cux-1 CAV isolate, were compared with those induced by a pathogenic, molecularly cloned, low-passage Cux-1 isolate (CI Cux).

Isolation and Preliminary Characterization of Chicken Anemia Virus from Chickens in Nigeria

Avian Diseases, 2005
Chicken anemia virus (CAV) was isolated for the first time from the Nigerian chicken population. The virus was recovered from necropsied birds from broiler and pullet flocks that suffered disease outbreaks tentatively diagnosed as infectious bursal disease.

Apoptosis-Inducing Proteins in Chicken Anemia Virus and TT Virus

2009
Torque teno viruses (TTVs) share several genomic similarities with the chicken anemia virus (CAV). CAV encodes the protein apoptin that specifically induces apoptosis in (human) tumor cells. Functional studies reveal that apoptin induces apoptosis in a very broad range of (human) tumor cells.

Chicken Anemia Virus

2009
Chicken anemia virus (CAV), the only member of the genus Gyrovirus of the Circoviridae, is a ubiquitous pathogen of chickens and has a worldwide distribution. CAV shares some similarities with Torque teno virus (TTV) and Torque teno mini virus (TTMV) such as coding for a protein inducing apoptosis and a protein with a dual-specificity phosphatase.

Chicken anemia virus induced apoptosis: underlying molecular mechanisms

Veterinary Microbiology, 2004
In 1990, the chicken anemia virus (CAV) genome was cloned by us and proven to be representative for CAV isolates worldwide. This genome contains unique promoter/enhancer replication elements and genes. Upon infection of its target cells, CAV replicates via a double-stranded (ds) DNA intermediate. From this ds CAV molecule, a single mRNA is transcribed,

Molecular evolution and pathogenicity of chicken anemia virus isolates in China

Archives of Virology, 2021
Chicken infectious anemia (CIA), caused by chicken anemia virus (CAV), is an important immunosuppressive disease that seriously threatens the global poultry industry. Here, we isolated and identified 30 new CAV strains from CAV-positive flocks. The VP1 genes of these strains were sequenced and analyzed at the nucleotide and amino acid levels and were ...
