Abstract
To investigate the reticuloendotheliosis virus
(REV) infection status in
China, 2531 sera samples from 26 farms of
native chickens were collected and tested for antibodies against
reticuloendotheliosis virus. Serum samples analysis revealed 32.16% samples
positive for REV-antibody. All 26 kinds of China native
chicken strains have REV infection. REV-antibody positive rates of different
flocks ranged from 1.01 to 67.68%. This study suggests that REV infection is
very common in China
native chickens flocks and more emphasis be given on its prevention.
