Effects of Chicken Anemia Virus and Infectious Bursal Disease Virus in Commercial Chickens

Avian Diseases, 2009
The effects of chicken anemia virus (CAV) and infectious bursal disease virus (IBDV) coinfection in commercial layer-type and meat-type (broiler) chickens with specific maternal immunity were evaluated. In addition, the broiler progeny used had been vaccinated in ovo against IBDV.

Molecular epidemiology of chicken anemia virus in Nigeria

Archives of Virology, 2005
Between February 2002 and May 2004, chicken anemia virus (CAV) was detected by PCR in organ samples from 14 flocks of poultry farms in Lagos, Ogun and Oyo States in Southwestern Nigeria. The farms reported low (

The contribution of feathers in the spread of chicken anemia virus

Virus Research, 2008
Chicken anemia virus (CAV) spreads vertically and horizontally, however, the process is mostly still obscure. To further clarify the horizontal CAV spread, we examined the contribution of feathers. We demonstrated that CAV could be amplified from DNA purified from feather shafts of experimentally infected chicks, and the process efficacy was evaluated ...

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).

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,

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.

Isolation and Identification of Chicken Infectious Anemia Virus in Brazil

Avian Diseases, 1991
Seven chicken infectious anemia virus (CIAV) isolates were obtained from seven broiler flocks with poor performance in two states of Brazil. All isolates induced thymus atrophy, bone-marrow aplasia, and low hematocrit values when inoculated into 1-day-old susceptible chicks. The CIAV isolates were resistant to treatment with chloroform and were able to

Immune Complex Vaccines for Chicken Infectious Anemia Virus

Avian Diseases Digest, 2011
Infection of maternal, antibody-negative chickens with chicken infectious anemia virus (CIAV) can cause clinical disease, while infection after maternal antibodies wane often results in subclinical infection and immunosuppression. Currently, vaccines are not available for vaccination in ovo or in newly hatched chickens. Development of CIAV vaccines for

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 ...

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.
