(d) Assay systems based on the measurement of specialized functions and viral products; a number of viruses do not produce plaques nor do they cause CPE readily, but they may be quantified by certain specialized functions based on their unique properties, for example, hemagglutination and hemadsorption tests used to study the antiviral activity against myxoviruses and ELISA, used to determine the extent of virus replication and, thus, obtain a measure of the inhibitory effect of various antiviral agents on virus replication, etc. On the other hand, the antiviral activity is determined by comparing the virus titers of infected cells, which have been cultured with a maintenance medium containing plant extracts or test substances and a maintenance medium without test material (Colegate and Molyneux, 1993) .	./cache/cord-315918-12rbbe8c.txt	./txt/cord-315918-12rbbe8c.txt
