摘要

蚕丝是泰国重要的经济和文化产品，但在养蚕过程中爆发的蚕核型多面体病毒（BmNPV）对其造成了威胁。BmNPV 感染家蚕的幼虫阶段，造成致命的病毒感染，并阻止幼虫进入蛹期。世界各地的丝绸生产国已描述了大量的 BmNPV 分离物。本研究通过从不同地区收集 18 个样本，分析了 BmNPV 在泰国的地理分布。对 BmNPV 样品进行了 PCR 分析，并对 8 份样本进行了全基因组测序。它们的基因组大小从 125,888 bp 到 126,783 bp 不等，由 138 个开放阅读框组成。虽然已测序的 BmNPV 基因组可进行系统发育上的区分，但未观察到地理和遗传距离之间的相关性，这表明泰国的 BmNPV 之间关系密切。

Distribution and genetic diversity of Bombyx mori nucleopolyhedrovirus in mass-reared silkworms in Thailand

Silk is an economically and culturally important product of Thailand that is threatened by the outbreaks of the Bombyx mori nucleopolyhedrovirus (BmNPV) in silkworm rearings. BmNPV infects the larval stages of the silkworm Bombyx mori, causing fatal viral infection and preventing the larvae from reaching the pupal stage. Numerous BmNPV isolates have been described from silk-producing countries from all over the world. In this study, the geographic distribution of BmNPV in Thailand was analyzed by collecting 18 samples from different regions. The BmNPV samples were analyzed by PCR and whole genome sequencing was performed for eight specimens. Their genome size ranged from 125,888 bp to 126,783 bp, comprising 138 open reading frames. Although the sequenced BmNPV genomes could be phylogenetically differentiated, no correlation between geographic and genetic distance was observed, indicating a close relationship between the BmNPV from Thailand.

期刊介绍： The Journal of Invertebrate Pathology presents original research articles and notes on the induction and pathogenesis of diseases of invertebrates, including the suppression of diseases in beneficial species, and the use of diseases in controlling undesirable species. In addition, the journal publishes the results of physiological, morphological, genetic, immunological and ecological studies as related to the etiologic agents of diseases of invertebrates. The Journal of Invertebrate Pathology is the adopted journal of the Society for Invertebrate Pathology, and is available to SIP members at a special reduced price.
