Efficacy of ribavirin in MDCK and MDCK/London cells. MDCK and MDCK-London cells were infected by a H1N1, b H3N2, and c influenza B viruses at M.O.I. of 0.1 followed by treatment with different concentrations of ribavirin for 72Â h. Cell viability was determined by MTT assay and quantified by a colorimetric ELISA reader at wavelength 540Â nm. The 50% of effective concentration (EC50) of ribavirin were calculated based on the cell viability results
