We tested recombinant human interferons-α 2, -β 1, and -γ against adenovirus serotypes 1 and 5 (group C), 3 and 7a (group B), and a wild strain isolated from an acutely ill child who later died. Pretreatment of WISH cells with interferon-γ for 24 h induced a dose-dependent inhibition of multiplication of all adenovirus strains tested, the TCID50 varying from 25 to 90 IU/ml. Human interferon-α 2 was unable to decrease adenovirus multiplication, while interferon-β 1, at 2000 IU/ml slightly lowered the yield of adenovirus. Similar results were obtained in HEp-2 and FS-4 cells, while A- 549 and peripheral blood mononuclear cells were insensitive to interferon-y. The difference between the effects of interferon-y and interferon-γ and β> on adenovirus multiplication in vitro suggests that its mechanism of antiviral action is different. %U https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-68-3-941
