Nevertheless, several licensed human antiviral agents are being used with cascade principle for treatment of animal diseases (e.g. acyclovir, idoxuridine and trifluridine against feline herpesvirus-1 ocular infection in cats) (Thiry et al. The discovery of PAA (Fig. 22.4) as an antiviral drug gave rise to intense research on its biological activities, which demonstrated PAA and its derivatives' ability to inhibit the replication of a number of viruses such as immunodeficiency, hepatitis and herpes viruses. To conclude with, equine herpesvirus type 1 (EHV-1) infection causes outbreak of respiratory and various neurological diseases in horses, against which acyclovir and valacyclovir are the most common drugs, but also IFN targeting IFNGR complex as a key mediator of virus-specific cellular immunity (Poelaert et al.	./cache/cord-016309-6mw8okmt.txt	./txt/cord-016309-6mw8okmt.txt
