The disease caused by cyprinid herpesvirus-3 (CyHV-3) severely impacts the natural freshwater ecosystem and damages carp and koi farming, however, the pathway of CyHV-3 transmission remains unclear. It is possible that the virus adheres to plankton, which then facilitate viral movement and transmission, and therefore, it is hypothesised that plankton are involved in the disease dynamics. In this study, plankton were collected at eight sites in the Iba-naiko lagoon; we detected and quantified CyHV-3 DNA from plankton samples. The results of the correlation analysis showed a significant positive correlation between CyHV-3 copies and the number of Rotifera, suggesting that CyHV-3 binds to and/or is concentrated by Rotifera. Our results suggest that plankton affect viral ecology in the natural environment.
由鲤疱疹病毒 3 型（CyHV-3）引起的疾病严重影响了天然淡水生态系统，并破坏了鲤鱼和锦鲤养殖业，然而，CyHV-3 的传播途径仍不清楚。病毒可能附着在浮游生物上，从而促进病毒的移动和传播，因此，有人假设浮游生物参与了疾病动态。在这项研究中，在伊波纳科泻湖的八个地点采集了浮游生物；我们从浮游生物样本中检测和定量了 CyHV-3 DNA。相关分析的结果表明，CyHV-3 拷贝数与轮虫数量之间存在显著的正相关，表明 CyHV-3 与轮虫结合和/或被轮虫浓缩。我们的结果表明，浮游生物影响自然环境中的病毒生态学。
