Table 1. Description of DENV type 1 isolates used in this study.
The blood meal titer refers to the concentration of infectious viral particles (expressed in log10-transformed focus-forming units per mL) measured in the artificial blood meal offered to mosquitoes. The passage history refers to the number of prior amplifications in C6/36 cells.
