Complexity of Diarrhea-Associated Viruses in Stunted Pigs Identified by Viral Metagenomics.

ABSTRACT: Viral diarrhea poses a severe threat to the health and growth of piglets, especially when caused by co-infection with multiple diarrhea-associated viruses. In this study anal swabs were collected from pigs older than 3 months from a farm in Gansu province, China, and subjected to viral metagenomic analysis. They had been suffering from diarrhea and their growth was significantly retarded. A total of 18 viruses were identified by high-throughput sequencing (HTS) in pooled samples from 22 stunted pigs and (separately) three healthy pigs. They included 15 diarrhea-associated RNA viruses with five porcine rotaviruses (PoRVs), porcine epidemic diarrhea virus (PEDV), a torovirus, and a sapelovirus present only in the stunted pigs. Among the identified PoRVs, PoRVBs showed a much greater genetic
