Abstract:

This study was aimed to detect the efficacy of antiviral drugs against feline infectious rhinotracheitis virus. F81 cell was used to construct a model for drug screening against feline infectious rhinotracheitis virus in vitro. Virus inhibition rate was detected with MTT assay and calculated with SPSS software. The IC50 of acyclovir, ribavirin, L-lysine, isatis root and Astragalus polysaccharides were 9.5,3.3,3.4,161.0 and 4.7 μg/mL, respectively,the IC50 of polyinosinic was 6.0 mg/mL. The TI of them were 76.8, 39.3, 2 588.0, 4.5, 78.7 and 5.8, respectively. The effect of L-lysine and Astragalus polysaccharides were most significant.

Key words: feline infectious rhinotracheitis virus; MTT; screening; antiviral drugs
