HIV-1 Patients May Harbor Viruses of Different Phylogenetic Subtypes: Implications for the Evolution of the HIV/AIDS Pandemic
Figure 1

Figure 1. A. Three distinct A1uI digestion patterns of PCR amplified protease gene representing single HIV-1 infections by viral strains of subtypes A, C, F (pattern #1), and subtypes B and D (patterns #2 and #3). B. The presence of two distinct A1uI digestion patterns (#1 and #2) of the protease gene in PBMC of the patient dually infected by viral strains of subtypes F and B (lane 3). Arrows indicate diagnostic fragments deteted by hybridization with the radioactive probe (2). MW represents molecular weight markers-Ø RF DNA, HaeIII digest.
