Recombinant Identification Program (RIP) and similarity plots analysis were performed for MSM0720 to identify parental subtypes. (A) Similarity distance analysis was performed using RIP from the Los Alamos National Laboratory HIV Database with default setting except for the window size of 300. (B) Similarity plots for MSM0720 using SimPlot software, with subtype reference strains A1, B, C, D, 01_AE, 07_BC, and 08_BC. These reference strains were verified above by RIP, which may contain the components of MSM0720.
