1. Full-Length Genomic Characterization of Chicken Anemia Virus in Turkey
ABSTRACT Chicken infectious anemia (CIA) is an immune-suppressive disease caused by chicken anemia virus (CAV). It is characterized by lymphoid atrophy, aplastic anemia, especially in chicks. In this study, full-length genomic characterization of CAV DNA from the broiler flocks in Turkey and phylogenetic analysis were aimed. In the study, CAV DNA were found

2. Experimental Coinfection of Chicken Anemia Virus and Mycoplasma gallisepticum Vaccine Strains in Broiler Chicks
ABSTRACT This study aimed at determining the clinical and pathological effects of the coinfection of young SPF chickens with chicken anemia virus (CAV) and Mycoplasma gallisepticum (MG) vaccine strains. The clinical signs, gross and microscopic lesions were determined after the experimental coinfection broilers with a CAV genotype 1 vaccine strain given intr

3. Performance comparison between broilers positive and negative for antibodies against the chicken anemia virus
The chicken anemia virus (CAV) is present in virtually every country investigated, Brazil including. The aim of this study was to determine what the difference in performance is between positive (progeny of breeders vaccinated or with natural infection) and negative broilers to the presence of antibodies against the CAV in currently intensive raising systems

4. Diverse uses of feathers with emphasis on diagnosis of avian viral infections and vaccine virus monitoring
The large amounts of feathers produced by the poultry industry, that is considered as a waste was explored for possible uses in various industries, such as meals for animals, biofuels, biodegradable plastic materials, combating water pollution and more. That review mentions these uses, but concentrate on the utilization of feathers for the diagnosis of viral

5. Occurrence of chicken anemia virus in backyard chickens of the metropolitan region of Belo Horizonte, Minas Gerais
The occurrence of CAV in backyard chickens in the metropolitan area of Belo Horizonte, Brazil, was evaluated. The spleen and thymus of chickens from different origins were collected for DNA extraction and nested-PCR. CAV genome was detected in 30% of the flocks (n=20) examined. CAV origin for backyard chickens is speculated, taking into consideration its wid

6. Detecção do vírus da anemia infecciosa das galinhas em Minas Gerais
A wide range study was conducted on chicken anemia virus (CAV) in order to investigate the occurrence of CAV in different chicken populations and potential sources of infection. Tissue and biological samples were studied by nested PCR and sequencing, including thirty-two industrial chickens, twenty subsistence chickens, twenty-eight commercial poultry live a

7. Cloning and expression of chicken anemia virus VP3 protein / Clonagem e expressão da proteína VP3 do vírus da anemia infecciosa das galinhas (CAV)
Purification of chicken anemia virus (CAV) VP3 protein, expressed in a prokaryotic expression system as histidine-tagged fusion protein is demonstrated in the present study. CAV particle was obtained from infected liver of chicken and DNA was extracted. The VP3 protein gene was amplified from the extracted DNA by polymerase chain reaction (PCR) and cloned. T

8. Comparação do desempenho de frangos positivos e negativos para a presença de anticorpos contra o vírus da anemia das galinhas
O vírus da anemia das galinhas – CAV (chicken anemia virus) está presente em praticamente todos os países com produção avícola investigados, inclusive no Brasil. O CAV causa a doença chamada de anemia infecciosa das galinhas em aves jovens, que se caracteriza por anemia, aplasia de medula óssea, retardo no crescimento, mortalidade variável (2 a 20

9. Prevalência de anticorpos contra o vírus da anemia infecciosa das galinhas em matrizes de corte na região sul do Brasil.
O vírus da anemia infecciosa das galinhas (CAV, de “chicken anemia virus”), causa doença em aves jovens, caracterizada por anemia aplástica, atrofia linfóide generalizada e conseqüente imunodepressão. A doença clínica ocorre quando os pintos são infectados durante as duas primeiras semanas de vida e pode ser evitada se as reprodutoras passarem a

10. Um protocolo de "nested-PCR" para detecção do vírus da anemia das galinhas
Este trabalho descreve o estabelecimento de um pro!tocolo de "nested-PCR" para a detecção do vírus da anemia das galinhas (CAV, chicken anemia virus), agente causador da anemia infecciosa das galinhas. Para a extração de DNA a partir de amostras clínicas um método baseado no uso de tiocianato de guanidina mostrou-se mais sensível e prático, do que o

11. Comparação de desempenho entre frangos positivos e negativos para anticorpos contra o vírus da anemia das galinhas
O vírus da anemia das galinhas (CAV - "chicken anemia virus") está presente em praticamente todos os países investigados, inclusive no Brasil. O objetivo deste trabalho foi determinar qual a diferença de desempenho, comparando frangos positivos (progênie de matrizes vacinadas ou com infecção natural) com frangos negativos para a presença de anticorpo

12. Molecular Basis of the Attenuation Exhibited by Molecularly Cloned Highly Passaged Chicken Anemia Virus Isolates
Chimeric virus experiments indicated that the pathogenicity and monoclonal antibody reactivity differences between two molecularly cloned, highly passaged chicken anemia virus isolates could be attributed to the VP1 amino acid change at residue 89. The introduction of this change into a pathogenic cloned low-passage isolate was not sufficient to cause attenu
