Adenoviruses are common infectious agents of poultry.
The avian adenoviruses are divided into three groups i.e.
group ?, group ? and group III. Group ? is composed of
5 species (A to E) and 12 serotypes (FAdV-1 to FAdV12) of avian adenoviruses of chickens, turkeys, goose
and duck [1-3]. The group ? adenoviruses are famous
for causing hydropericardium-syndrome in chickens
(caused by FAdV-4 strains), Quail Bronchitis in quail
(caused by FAdV-1) and inclusion body hepatitis [4-6].
Group ? of avian adenoviruses causes hemorrhagic
enteritis in turkeys, marble spleen disease in pheasants
and splenomegaly in chickens. Group ? viruses have a
common group antigen that differentiates them from
group ? [7].
