Inhibition of Feline Calicivirus

We conducted feline calicivirus (FCV) inhibition experiment with two anti-viral aminohydrolases, asparaginase and glutaminase. We found that in the presence of 8 units and 4 units / ml of asparaginase, about 90% of FCV replication was inhibited. In contrast, glutaminase showed no significant inhibition effect on the virus replication. We have also shown that asparaginase did not inhibit the replication of adenovirus suggesting that the inhibition was specific. Our results implicated that asparaginase could be used as a candidate for anti-FCV drug development.
