Phylogenetic analysis of K1 amino acid sequence to determine KSHV genotype of each individual. A maximum likelihood tree was generated with K1 sequences generated in this study and 11 prototypic reference sequences obtained from GenBank. Sequences generated in this study are boxed and reference sequences are labeled A1, A2, A3, A4, A5, B, C1, C3, D1, D2, and E.
