Table 2. Subdivisions identified by Automatic barcode gap discovery (ABGD) analysis of whole genome sequences of HPIV3 and hypervariable region of human parainfluenza viruses type 3 (HPIV3).

The corresponding subdivisions into clusters, subclusters and strains, identified by ABGD for whole genome sequences ( Figure 4 and the hypervariable region of HPIV3 ( Figure 6) are summarized.
