Figure 2. Relationships between turkey hepatitis virus (THV) and other picornaviruses. The phylogenetic analyses were based on amino acid sequences of the combined 2C, 3C, and 3D regions (A), the P1 region (B), and complete coding regions, excluding divergent aa 799–1199 (C). Representative sequences from different picornavirus genera and recently discovered, unclassified viruses were obtained from GenBank; accession numbers are indicated. Bootstrap values are given at the respective nodes; scale bars indicate number of amino acid substitutions per site. TMEV, Theiler’s murine encephalomyelitis virus; EMCV, encephalomyocarditis virus; SVV, Seneca Valley virus; HCoSV-A1, human cosavirus A1; HCoSV-D1, human cosavirus D1; ERBV, equine rhinitis B virus; ERAV, equine rhinitis A virus; BRBV, bovine rhinitis B virus; FMDV, foot-and-mouth disease virus; PTV, porcine teschovirus; PSV, porcine sapelovirus; SSV, simian sapelovirus; ASV, avian sapelovirus; HRV-C, human rhinovirus C; CV-A21, coxsackievirus A21; EV-96, enterovirus 96; TV-2, turdivirus 2; TV-3, turdivirus 3; TV-1, turdivirus 1; AiV, Aichi virus; BKV, bovine kobuvirus; PKV, porcine kobuvirus; AEV, avian encephalomyelitis virus; HAV, hepatitis A virus; SePV, seal picornavirus; DHAV, duck hepatitis A virus; HPeV, human parechovirus; LV, Ljungan virus.
