Abstract:
Bats are important reservoir animals and more than 60 viruses have been identified in bats with many of them highly pathogenic to human. In order to understand the natural background, genetic diversity of bat viruses in China and discover potential viral pathogens, Solexa sequencing based viral metagenomics focusing on bats tissues was established and to analyze the virome of bats collected from Jilin, Yunnan and Hunan province. By Solexa sequencing, 116 442 324 useful reads were obtained and assembled into 4 872 contigs, of which 8.2% (4 002/4 4872) were annotated to 36 viral families, including 19 vertebrate virus families, 6 plant virus families, 4 insect virus families and 4 phages. Further contigs analyses showed that some adenovirus, bocavirus, picobirnavirus, parvovirus contigs sequences were similar with known viruses. However, part of them shared limited identities to these viruses implying the discovery of new viruses. Moreover, PCR validation of adenovirus and bocavirus confirmed the results obtained by viral metagenomics. This study aimed to understand bat virome in China by viral metagenomics and could be helpful to establish effective surveillance on wildlife-associate zoonoses.
