Abstract

Between 2018 and 2021, significant die-offs of Prussian carp (Carassius gibelio) occurred in five lakes in eastern, central and northern Serbia. In all cases, Cyvirus cyprinidallo 2, formerly named Cyprinid herpesvirus 2 (CyHV-2) infection was suspected, based on initial diagnostic observations. To determine the cause of these mass mortalities, real-time PCR assays targeting CyHV-2, CyHV-3, and SVCV were conducted. CyHV-2 DNA was detected in the affected populations, while SVCV and CyHV-3 were negative in the assay. The CyHV-2 was also detected in asymptomatic Prussian carp. Sequence analysis of the CyHV-2 DNA polymerase and helicase genes revealed high similarity to previously reported strains from Serbia and other countries. The occurrence of these outbreaks in Prussian carp populations in lakes indicates the probable spread of the virus within freshwater ecosystems in Serbia, potentially impacting the degradation of aquatic habitats.
鲤科病毒2型(CyHV-2)在塞尔维亚湖泊普鲁士鲤鱼中的出现和持续
2018年至2021年期间,在塞尔维亚东部、中部和北部的五个湖泊中,普鲁士鲤鱼(Carassius gibelio)大量死亡。在所有病例中,根据初步诊断观察,怀疑感染了原称为CyHV-2 (CyHV-2)的cyprinidallo 2病毒。为了确定这些大规模死亡的原因,进行了针对CyHV-2、CyHV-3和SVCV的实时PCR检测。在感染人群中检测到CyHV-2 DNA,而SVCV和CyHV-3在检测中为阴性。在无症状鲤鱼中也检测到CyHV-2。序列分析显示CyHV-2 DNA聚合酶和解旋酶基因与塞尔维亚和其他国家先前报道的菌株高度相似。在湖泊中的普鲁士鲤鱼种群中发生这些暴发表明,该病毒可能在塞尔维亚的淡水生态系统中传播,可能影响水生生境的退化。

期刊介绍: Aquaculture is an international journal for the exploration, improvement and management of all freshwater and marine food resources. It publishes novel and innovative research of world-wide interest on farming of aquatic organisms, which includes finfish, mollusks, crustaceans and aquatic plants for human consumption. Research on ornamentals is not a focus of the Journal. Aquaculture only publishes papers with a clear relevance to improving aquaculture practices or a potential application.
