Abstract
The rapid spread of subgroup J avian
leucosis virus (ALV-J) and stunting effect on
chickens are noticed by the poultry industry.
Most breeders are imported. Since most
breeding companies has claimed that they
have control ALV-J infection in chickens, we
would like to know the infection status of the
imported chickens as well as their offspring
in the field. The purpose of the present study
is to investigate the situation of ALV-J
infection in Taiwan broiler and native
chickens. Since ELISA fails to distinguish
exogenous and endogenous ALV, virus
isolation was used in this study. The
contamination rate of broilers was 62.5%.
One native breeder farms showed signs and
lesions of ALV-J infection, while no virus
was isolated from native meat-type chickens
with %-15% anti-ALV-J antibody. The
phylogenetic analysis of the ALV-J isolates
from breeders, broiler, native chickens were
compared with reference strains. The results
show that ALV-J is changing during this
investigation, and more attention should be
paid to the control of ALV-J in Taiwan.
