Studies on Reclassifying of Periplaneta fuliginosa Densovirus
Institute ofVirology,Wuhan Universi~,Wuhan430072,China J
Abstract:Periplaneta fuliginosa densovirus(pfDNV)was found in China at the first time,has been
classified into the subfamily Densovirinae in Parvoviridae.However,Which genus that it be longs to has
not yet been determined and is the focus of the present work.Recent advances in the investigation of
pfDNV include two aspects:the sequence of the complete genome of the virus an d the threedimensional
reconstruction of the virus at the resolution of 23A using the techniques of cryo—electron
microscopy and image reconstruction.W ith these data.pfDNV is extensively compared in the present
WOrk with other Parvoviruses with respect to the characteristics 0f the genome organisations an d
three-dimensional structures.Our results do not support the current classification of pfDNV.Therefore,
a suggestion is m ade to reclassify pfDNV.
