Alcohol disinfection procedure for isolating giant viruses from contaminated samples.

abstract：BACKGROUND/AIMS:Cardiovirus is a genus of viruses belonging to the family Picornaviridae. Here, we used viral metagenomic techniques to detect the viral nucleic acid in the fecal samples from wild rats in Zhenjiang city in China. METHOD:Fecal samples were collected from 20 wild rats and pooled into four sample pools a...
