Abstract

This study reports on the first evidence of genomic material of the causative agent for epizootic ulcerative syndrome (EUS), , from fish in the Limpopo River system and the Kruger National Park, South Africa. Fourteen fish species were collected from various depressions in the floodplains of the Limpopo and Luvuvhu Rivers in the Makuleke Wetlands during 2015 and 2017. A single individual of was found to have a suspected epizootic ulcerative syndrome (EUS) lesion. Samples were collected and evidence of DNA in the samples was found through PCR and amplicon sequencing. The spread of EUS into this premier conservation area is of concern as it could potentially spread across borders and into other naïve river systems with important conservation statuses.

摘要

本研究报告了南非林波波河系统和克鲁格国家公园鱼类身上首次发现的流行性溃疡综合征（EUS）病原体基因组物质的证据。2015年至2017年期间，从马库莱克湿地林波波河和卢武武河泛滥平原的各个洼地收集了14种鱼类。发现一条鱼个体有疑似流行性溃疡综合征（EUS）病变。采集了样本，并通过聚合酶链反应（PCR）和扩增子测序在样本中发现了 DNA的证据。EUS扩散到这个主要保护区令人担忧，因为它可能会跨境传播到其他具有重要保护地位的未受影响的河流系统。
