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 ().
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.
Six fish specimens were positive for the presence of KHV, while none of the gobies examined showed the presence of CEV.
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.
本研究的目的是确定由入侵的圆口铜鱼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。
2018年第三和第四季度，从波兰什切青泻湖和德国的一些地点共采集了70份圆口铜鱼样本。通过聚合酶链反应（PCR）对这些鱼进行分析，以检测KHV和CEV。
6份鱼样本检测出KHV呈阳性，而所检测的圆口铜鱼均未显示存在CEV。
在来自德国和波兰的圆口铜鱼样本中检测到了CEV基因组。鉴于圆口铜鱼的传播速度快及其在获取新生态位方面的有效性，在鲤鱼池塘重新注水时应防止其进入。进一步的研究应集中于CEV感染的圆口铜鱼与无特定病原体（SPF）鲤鱼的实验同居，以研究病毒主动传播的可能性。
