“…Phylogenetic analyses done for both farmed and feral mink AMDV strains show that the strains can be divided into three to six genetic groups Jensen et al, 2012;Knuuttila et al, 2009a;Leimann et al, 2015;Nituch et al, 2012;Olofsson et al, 1999;Sang et al, 2012;Schuierer et al, 1997;Wang et al, 2014). Within these groups there is no apparent clustering linked to pathogenicity (ability to cause disease) (Knuuttila et al, 2009a;Nituch et al, 2012;Olofsson et al, 1999;Schuierer et al, 1997). Grouping based on geographical origin has been detected in some countries or regions Jensen et al, 2012;Nituch et al, 2012;Sang et al, 2012), but not in others 2009a, Leimann et al, 2015Wang et al, 2014).…”
