Figure 2. Parsimony networks based on the partial (A) N and (B) F genes of the PPRV isolates belong to lineage IV.

Each colored circle represents a unique gene sequence (haplotype), and the size of the circle is proportional to the number of isolates of that haplotype. Country of origin is indicated by unique color. Each empty circle between two adjacent colored circles represents the hypothetical mutational step not observed in the sample. All the isolates were connected at 95% confidence limit (connection limit = 7 mutations). The existence of multiple clusters in India and Pakistan are highlighted in N-and F genes, respectively.
