Abstract
In this study we show that a type I-IFN inducing compound, S-28828, modulated the pathogenesis of an avian type II adenovirus in turkeys. By itself, S-28828 induced a strong reaction in the spleen characterized by hyperplasia of the red and white pulps as well as an increase in lymphoid cell aggregations. Oral administration of S-28828 before the time of virus inoculation suppressed significantly (P<0.05) the replication of hemorrhagic enteritis virus (HEV) in turkeys. Two doses of 5 or 50 mg of S-28828 administered at 2 days before and at the day of virus inoculation inhibited HEV-induced pathological and histopathological lesions. Virus-induced apoptosis and reduced IgM-surface expression of B cells were suppressed by low dose S-28828 treatment. These results are of interest because mammalian adenoviruses were shown to be resistant to antiviral effects of type I IFN, the major effector cytokine induced by S-28828.
