A porcine enterovirus G associated with enteric disease contains a novel papain-like cysteine protease.

ABSTRACT: Identification of unknown pathogens in pigs displaying enteric illness is difficult due to the large diversity of bacterial and viral species found within faecal samples. Current methods often require bacterial or viral isolation, or testing only a limited number of known species using quantitative PCR analysis. Herein, faeces from two 25-day-old piglets with diarrhoea from Texas, USA, were analysed by metagenomic next-generation sequencing to rapidly identify possible pathogens. Our analysis included a bioinformatics pipeline of rapid short-read classification and de novo genome assembly which resulted in the identification of a porcine enterovirus G (EV-G), a complete genome with substantial nucleotide differences (>30 %) among current sequences, and a novel non-structural protein simila
