Fig. 4From: Differences in genome characters and cell tropisms between two chikungunya isolates of Asian lineage and Indian Ocean lineageSuspension cells are differently susceptible to chikungunya virus infection. (a) Quantification of the viral RNA load by real-time qRT-PCR from the supernatants infected with SZ1050 MOI of 5 at 0, 24, 48 and 72Â h. (b) Quantification of the viral RNA load by real-time qRT-PCR from the supernatants infected with SZ1239 MOI of 5 at 0, 24, 48 and 72Â h. (c) Comparison of viral RNA increasing folds in the supernatant and infected cells between SZ1050 and SZ1239 at 24Â h. p. iBack to article page
