Fig. 1.

Molecular phylogenetic inference with Alpha-, Beta-, Gamma-, and DeltaCoV groups by ML method under GTR evolutionary model for the partial RdRp gene (267 bp). The colors represent CoVs detected in wild birds grouped with BetaCoV (red) and DeltaCoV (highlighted in blue) groups. The asterisk represents the bird samples from which the DNA sequences were obtained. The number within parenthesis shows the nucleotide identities of PorCoV HKU15 and SpaCoV HKU17 (both DeltaCoVs) with the CoV detected in Amazona vinacea. The letter X represents the arithmetic mean of nucleotide identities between the CoVs detected in the study and the MHV A59. The GenBank accession numbers of sequences deposited (from study) and retrieved from the database are shown in the tree. PorCoV porcine coronavirus; HCoV human coronavirus; PEDV porcine epidemic diarrhea virus; BatCoV bat coronavirus; TGEV transmissible gastroenteritis coronavirus; CCoV canine coronavirus; IBV infectious bronchitis virus; TCoV turkey coronavirus; MHV mouse hepatitis virus; BCoV bovine coronavirus; SARS severe acute respiratory syndrome; MERS middle east respiratory syndrome coronavirus; PToV (outgroup) porcine torovirus. The numbers above the branches represent the SH-like support values of 1000 replicates. Only values greater than or equal to 70 % are presented. Online version in color
