The exact mechanism of action of omega interferon is not perfectly known, but may involve the enhancement of the non-specific defence of the body, in particular in the dog against canine parvovirosis. Interferon does not act directly and specifically against the pathogenic virus, but exerts its effect by inhibition of the internal synthesis mechanisms of the infected cells. Omega interferon of feline origin, produced by genetic engineering, is a type 1 interferon related to alpha interferon. After injection it is quickly bound to specific receptors of a large variety of cells. It is mainly in cells infected by the virus that the mechanism of replication is stopped both by destruction of mRNA and by inactivation of translation proteins (2’ 5’ oligo-adenylate synthetase activation).
