Genetic characterization of a second novel picornavirus from an amphibian host, smooth newt (Lissotriton vulgaris)

Genetic characterization of a second novel picornavirus from an amphibian host, smooth newt... In this study, a novel picornavirus was identified in faecal samples from smooth newts (Lissotriton vulgaris). The complete genome of picornavirus strain newt/II-5-Pilis/2014/HUN (KX463670) is 7755 nt long with type-IV IRES and has 39.6% aa sequence identity in the protein P1 to the corresponding protein of bat picornavirus (KJ641686, unassigned) and 42.7% and 53.5% aa sequence identity in the 2C and 3CD protein, respectively, to oscivirus (GU182410, genus Oscivirus).

Abstract

In this study, a novel picornavirus was identified in faecal samples from smooth newts (Lissotriton vulgaris). The complete genome of picornavirus strain newt/II-5-Pilis/2014/HUN (KX463670) is 7755 nt long with type-IV IRES and has 39.6% aa sequence identity in the protein P1 to the corresponding protein of bat picornavirus (KJ641686, unassigned) and 42.7% and 53.5% aa sequence identity in the 2C and 3CD protein, respectively, to oscivirus (GU182410, genus Oscivirus). Interestingly, the L-protein of newt/II-5-Pilis/2014/HUN has conserved aa motifs that are similar to those found in phosphatase-1 catalytic (PP1C) subunit binding region (pfam10488) proteins. This second amphibian-origin picornavirus could represent a novel species and could be a founding member of a potential novel picornavirus genus.
