From: Astrovirus as a possible cause of congenital tremor type AII in piglets?
Phylogenetic analysis of astroviruses demonstrated in brain tissue from piglets with congenital tremor (●) and in brain tissue from healthy control piglets (▲). The phylogenetic analysis was performed using Neighbour-joining algorithm and bootstrap value of 1000. Only branch support over 70% is displayed in the figure. If several regions of the brain of one individual were positive for the same PoAstV linage, only one of the sequences was used in the tree.
