摘要: Near-complete genome sequences of seven picornavirus (PV) strains isolated from different terrestrial tortoise species were determined and characterized. The organization the proved to be similar displayed a typical PV layout, polyprotein-encoding regions showed low similarity those other PVs. predicted genomes related corresponding parts viruses belonging distinct genera, implying modular evolution these novel viruses. Our results suggest that PVs belong prototype in separate proposed genus family Picornaviridae, tentatively called Topivirus (Tortoise picornavirus).
