摘要

本研究描述了2021年哥伦比亚北海岸两个虾场IHHNV感染的诊断和报告情况。首次在出口的冷冻凡纳美对虾样本中检测到IHHNV病毒。流行病学调查显示，两个养殖场的IHHNV感染率分别为97% %和36% %。组织病理学未见包涵体，但原位杂交证实感染。系统发育分析确定哥伦比亚的IHHNV分离株为基因型II，与厄瓜多尔、巴西和美国的毒株相似。这些发现强调了将分子诊断、基因组测序和组织病理学与原位杂交结合起来进行全面的IHHNV检测和表征的重要性。

A case report about the detection of infectious hypodermal and hematopoietic necrosis virus (IHHNV) in shrimp displaying no clinical signs or histopathological lesions from farms on Colombia’s north coast

This study describes the diagnosis and reporting of IHHNV infection in two shrimp farms on Colombia’s north coast in 2021. IHHNV was first detected in frozen Penaeus vannamei samples for export. Epidemiological investigation revealed IHHNV prevalence of 97 % and 36 % in the two farms using WOAH-recommended PCR. Histopathology showed no inclusion bodies, but in situ hybridization confirmed infection. Phylogenetic analysis identified the Colombian IHHNV isolates as genotype II, similar to strains from Ecuador, Brazil, and the US. These findings emphasize the importance of integrating molecular diagnostics, genome sequencing, and histopathology with in situ hybridization for comprehensive IHHNV detection and characterization.

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.
