Epidemiology, Phylogeny, and Evolution of Emerging Enteric Picobirnaviruses of Animal Origin and Their Relationship to Human Strains
Figure 5
Phylogram showing genetic relatedness between animal and human Picobirnaviruses based on partial RdRp gene sequences retrieved from the GenBank database (http://www.ncbi.nlm.nih.gov/). (a) Genogroup I Picobirnaviruses of various species; (b) genogroup II Picobirnaviruses of human, porcine, and bovine origin. Phylogenetic tree was constructed by neighbor-joining (NJ) method implemented in MEGA5 (http://megasoftware.net/). Numbers on branches indicate percentages of bootstrap support from 2,000 replicates.
