Fig. 3From: Epidemiology of Astrovirus, Norovirus and Sapovirus in Greek pig farms indicates high prevalence of Mamastrovirus suggesting the potential need for systematic surveillancePhylogenetic analysis of nucleotide sequences from the ORF1b gene (183-bp fragment) of 47 PAstV strains detected in this study and 5 PAstV reference sequences. The sequences that correspond to PAstV3, detected in the present study, are indicated with pink triangles ( ). The sequences of PAstV1 detected in the present study are indicated with green rhomb ( ) and the sequences of PAstV4 are indicated with blue circles ( ). GenBank accession numbers are shown on the treeBack to article page
