Our mass sequencing data revealed that some sequences showed possible infection with human bocavirus, which belongs to the Parvoviridae family. PCR performed to detect human bocavirus tentatively identified in sera from FTLS patient samples amplified a 291-bp fragment of the NS1 gene, as described previously [29] . Amplified products were detected by agarose gel electrophoresis and sequenced using an ABI 3730 DNA Sequencer.
