Replication Kinetics and Viral RNA Copy Fluctuations (gRNA and sfRNA) of DENV-1 Lineages and Strains in Huh-7 Mammalian Cells

In vitro experiments were conducted at an MOI of 0.1. The y axis represents virus titers (pfu/mL), whereas the x axis refers to hours post infection (hpi). The bar chart shows the sfRNA:gRNA ratio for each isolate at 24 hpi. SG(EHI)D1/0091Y09, SG(EHI)D1/15834Y11, SG(EHI)D1/18640Y12, and SG(EHI)D1/44259Y12 isolates possess the 21-nucleotide deletion in the hypervariable region of the 3′ UTR (please see also Figure S2). The deletion is absent in SG(EHI)D1/09106Y11; SG(EHI)D1/04009Y13; SG(EHI)D1/30889Y14; SG(EHI)D1/09063Y15; 05K4441DK1/2005; and 05K4443DK1/2005 isolates. D1, DENV-1; GI, genotype I; GIII, genotype III; w/o, without; del, deletion. ***p ≤ 0. 001.
