Investigation of the attenuation exhibited by a molecularly cloned chicken anemia virus isolate by utilizing a chimeric virus approach.
Molecular cloning of the Cux-1 isolate of chicken anemia virus (CAV), which had been passaged 173 times in cell culture, resulted in the isolation of an attenuated strain, designated cloned isolate 10, which reverted to virulence following 10 passages in young chicks (D. Todd, T. J. Connor, V. M. Calvert, J. L. Creelan, B. M. Meehan, and M. S. McNulty, Avian Pathol. 24:171-187, 1995). The atten...

Postmortem examination revealed severe hemorrhages in the wings and muscle...
متن کاملExperimental studies of pathogenecity of Chicken Infectious Anaemia Virus (3 isolates) in Iran
To evaluate pathogenicity of 3 Chicken Anemia Virus isolates-CV1, CV2 and CV3 respectively - the current experiment carried out. After tittering of the viruses, 30 one day old SPF chicks were grouped and intramuscularly inoculated with each isolate in a separate group. Two other groups as positive and control groups were inoculate with a live vaccine virus and normal saline respectively. During...
