RV SA11.4F growth curves in MDCK and HT29.F8 cells. The kidney and intestinal cell lines were RV infected at MOI = 2. At 2 to 48 hpi, the media was collected to assess for released virus or cells and media were collected to evaluate total virus production. Samples were titered for RV by determining the FFU/ml. The average of 3 different assays for each time point is graphically shown.
