摘要

圈养的远洋红蟹（Pleuroncodes planipes）寿命缩短，皮肤出现黑斑。组织学上，表皮和间充质细胞有3-5µm直径的核内包涵体、坏死、空泡化和/或增生。其余器官在组织学上无明显变化。超微结构上，细胞核含有棒状、70-100nm × 250- 350nm的双膜病毒粒子。32只动物的PCR检测结果为阴性，提示WSSV为新型病毒。由于从石蜡包埋组织中获得的DNA数量很少，因此无法检索病毒的基因组序列。这与一种新型病毒感染相一致，并且是对远洋红蟹中病毒性疾病的首次描述。

A novel viral infection in a Captive Colony of pelagic red crabs (Pleuroncodes planipes) from California.

Captive, pelagic red crabs (Pleuroncodes planipes) had shortened lifespans and cutaneous black spots. Histologically, epidermal and mesenchymal cells had 3-5 µm diameter intranuclear inclusions, necrosis, vacuolation, and/or hyperplasia. The remaining organs were histologically unremarkable. Ultrastructurally, nuclei contained rod-shaped, 70-100nmx250-350 nm virions with a double membrane. PCR on 32 animals was negative for WSSV, and suggestive of a novel virus. The genomic sequence of the virus could not be retrieved due to the low amount of DNA obtained from the paraffin embedded tissue. This is consistent with a novel viral infection, and is the first description of a viral disease in pelagic red crabs.

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.
