Background and Aims: Finding prevalence of chicken anemia virus (CAV) infection in native chickens is necessary to avoid transmission of infection to commercial flocks. In this paper we attempt to describe molecular detection of chicken anemia virus in native Larry-breed chickens in Chaharmahal-va-Bakhtiyari province in Iran for the first time. Materials and Methods: Blood samples were collect...

Infectious salmon anemia (ISA) is one of the most important viral diseases of farmed Atlantic salmon. This highly contagious disease can be insidious, with an initially low mortality rate; however, the cumulative mortality can sometimes exceed 90% if the disease remains unchecked. Infectious salmon anemia was first described in Norway in 1984, and it continues to be a problem in that country de...

The genus Gyrovirus was assigned to the family Anelloviridae in 2017 with only one recognized species, Chicken anemia virus. Over last decade, many diverse viruses related chicken virus have been identified but not classified. Here, we provide a framework for classification of new species and communicate establishment nine species. We adopted ‘Genus + freeform epithet’ binomial system naming th...

The antibody to chicken infectious anemia virus (CIAV) was positive in a specific pathogen-free (SPF) chicken population by ELISA test in our previous inspection, indicating a possible infection with CIAV. In this study, blood samples collected from the SPF chickens were used to isolate CIAV by inoculating into MSB1 cells and PCR amplification. A CIAV strain (SD1403) was isolated and successful...

Chicken anemia virus (CAV) causes diseases in young chickens, which include increased pathogenicity of secondary infectious agents, generalized lymphoid depletion, and immunodepression. In the present study, we have identified 22 CAV strains isolated from several commercial chicken farms in Northern China during 2014-2015. In addition, two CAVs were also isolated from stray mouse and dog feces,...

equine infectious anemia (eia) is a contagious disease that is clinically characterized by recurrent episodes of fever, hemolytic anemia, icterus, depression, edema and chronic weight loss. the disease is associated with a persistent viral infection. the virus of eia is a member of the retroviridae family. the aim of this study was to determine the status of eia in horses in ahvaz. one hundred ...

background and aims: infectious laryngotracheitis virus (iltv) infection causes a highly contagious respiratory disease in poultry leads to significant economic losses in the poultry industry. the genomic and antigenic characteristics between virulent and vaccine strains of iltv are very similar. the ability of embryonated chicken neural stem (cns) cell for differential diagnosis of iltv strain...

One-day-old SPF chicks were inoculated with the Cux-l strain of chicken infectious anemia virus (CIAV), and the clinical development of disease and its macroscopic and microscopic alterations in the thymus and bone marrow, were observed. Tissue sections of thymus and bone marrow were stained using the streptavidin-biotin peroxidase method and examined under light microscope for evaluation of an...

In the present study recombinant VP3 (rVP3) was expressed in E. coli BL21 (DE3) (pLysS) and its polyclonal antibodies were characterized. SDS-PAGE analysis revealed that the expression of recombinant protein was maximum when induced with 1.5 mM IPTG for 6 h at 37 degrees C. The 6xHis-tagged fusion protein was purified on Ni-NTA and confirmed by Western blot using CAV specific antiserum. Rabbits...
