摘要

摘要：黑胸大蠊浓核病毒(pfDNV)是在我国首先发现并正式分类鉴定的蟑螂浓核病毒。该病毒属细小病毒科 (Parvoviridae)，浓核病毒亚科(Densovirinae)。但对该病毒的归属问题却一直没有确定，本文对此予以探讨。pfDNV 的最新研究进展包括两个方面：全基因组核苷酸序列的测定，以及利用低温电镜技术和像重构方法对该病毒的三维重构(分辨率23 A)。在此基础上，本文将pfDNV与其它病毒在基因组结构和三维结构方面进行了全面的对比分析，其结果并不支持目前对pfDNV的分类，因此建议对该病毒重新进行分类。

Abstract

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．
