Phylogenetic analysis. Maximum-likelihood trees constructed with a the capsid protein precursor (encoded by ORF2) and b the nonstructural polyprotein nsp1ab (derived from the common translation of ORF1a and ORF1b) full-length amino acid sequences of the new astrovirus strain MOxAstV-CH18 and selected astroviruses. Both trees demonstrate the close relationship of MOxAstV-CH18 to ovine astrovirus 1 (OvAstV-1). Note that various ovine and bovine neurotropic astroviruses also cluster with MOxAstV-CH18 and OvAstV-1. GenBank accession numbers are shown in brackets. Neurotropic strains are indicated with rhombi. Scale bars illustrate p-distances. AvAstV, avian astrovirus; BoAstV, bovine astrovirus; HuAstV, human astrovirus; MiAstV, mink astrovirus; OvAstV, ovine astrovirus; PoAstV, porcine astrovirus; StAstV, Sichuan takin astrovirus
