Abstract Introduction The aim of the study was to determine the transmission potential of carp edema virus (CEV) and koi herpesvirus (KHV) introduced to Europe by the invasive round goby (Neogobius melanostomus). Material and Methods A total of 70 round goby specimens were collected from the Szczecin Lagoon, Poland, and locations in Germany in the third and fourth quarters of 2018. The fish were analysed to detect KHV and CEV by PCR. Results Six fish specimens were positive for the presence of KHV, while none of the gobies examined showed the presence of CEV. Conclusion The CEV genome was detected in the goby specimens from Germany and from Poland. Considering the high pace of the spread of the round goby and its effectiveness in acquisition of new ecological niches, it should be kept out during refilling of carp ponds. Further studies should focus on experimental cohabitation of CEV-infected round gobies and specific-pathogen-free (SPF) carp to investigate the potential for active virus transfer.

1814 年来自波兰和德国的侵入性圆形虾虎鱼 (Neogobius melanostomus Pallas) 中锦鲤疱疹病毒 (KHV) 和鲤鱼水肿病毒 (CEV) 的检测

摘要 介绍 本研究的目的是确定由侵入性圆形虾虎鱼 (Neogobius melanostomus) 引入欧洲的鲤鱼水肿病毒 (CEV) 和锦鲤疱疹病毒 (KHV) 的传播潜力。材料与方法 2018 年第三季度和第四季度从波兰什切青泻湖和德国的地点共采集了 70 只圆形虾虎鱼标本。通过 PCR 对鱼进行分析以检测 KHV 和 CEV。结果 6 份鱼标本中 KHV 呈阳性,而检查的虾虎鱼均未发现 CEV。结论 在德国和波兰的虾虎鱼标本中检测到 CEV 基因组。考虑到圆虾虎鱼的快速传播速度及其在获取新生态位方面的有效性,在鲤鱼池补水期间应将其拒之门外。
