ABSTRACT
Objective@#To understand the potential viral pathogens other than enteroviruses existing in samples of hand foot and mouth disease (HFMD) patient and study their molecular feature and genotype.@*Methods@#The deep sequencing analysis of a fecal specimen collected from HFMD patient was conducted by metagenomics and bioinformatics.@*Results@#Enterovirus A71 and sapovirus mixed infection was found in this case. The nucleic acid of sapovirus was confirmed positive by RT-PCR and the 7 429 bp complete genome sequence of sapovirus was obtained by assembling sequencing reads which consisted of 3 open reading frames. Phylogenetic analysis revealed that this strain of virus should belong to the genotype 1 of sapovirus having a homology of 99.4% with sapovirus Hu/G1/Zhejiang1/China/2014 strain, which is a currently predominant genotype circulating in China.@*Conclusions@#The sapovirus, which is a predominant strain circulating in China, was a mixed infected causative agent existing in HFMD sample identified by deep sequencing. This study will serve as a reference for pathogen detection of HFMD and diarrheal related diseases, as well as provide a sequence reference for molecular feature study of sapovirus in China in the future.
