Figure 6. Phylogenetic relationships among pneumovirus pathogens.
Tree constructed from nucleotide sequences of the pneumovirus SH genes using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) method as per algorithms within MEGA 4.0 (Tamura et al., 2007); 2000 bootstrap replicates, values > 50 as shown. GenBank reference numbers include: PVM J3666, AY573815; PVM strain 15 AY743910.1; bovine RSV (ATCC 51908), AF295543.1; human RSV, NC_001781.
