Phylogenetic analysis of genogroup II picobirnaviruses. Neighbor-joining (Jukes-Cantor model) phylogenetic tree of an ≈339-bp fragment (reference strain 4-GA-91 (9) of the picobirnavirus genogroup II RNA-dependent RNA polymerase gene from known human picobirnaviruses and newly characterized porcine picobirnaviruses in this study (JN176312–315, shown in red). Significant bootstrap values are shown. Nomenclature of depicted viruses is according to recent proposals (7). PBVII/Homo sapiens/USA-4-GA-
