Abstract

One hundred serum samples collected from free-ranging white rhinoceros (Ceratotherium simum) in Kruger National Park (KNP) during the 2007 capture season were selected for measurement of antibody levels to several different vector-borne viral agents. These infectious diseases were chosen to compare with an earlier serosurvey that had been conducted in KNP in rhinos during 1987-1997. Positive antibody titers were found against epizootic hemorrhagic disease (EHD) of deer (8%), Bluetongue (BT) (1%), and Rift Valley fever (RVF) (49%). However, none of the 100 animals tested had detected antibody levels to African horse sickness (AHS). These values were in sharp contrast to those measured in the 1987-1997 survey in KNP white rhinos (AHS 60%, EHD 30%, BT 37%, RVF 0%). Vector-borne viral infection prevalence in white rhinos in the same geographical location appears to vary over time and may be important for monitoring presence of pathogens in an ecosystem.

摘要

从2007年捕获季节克鲁格国家公园（KNP）自由放养的白犀牛（白犀属）采集的100份血清样本，被选来检测针对几种不同媒介传播病毒病原体的抗体水平。选择这些传染病用于与1987年至1997年期间在KNP对犀牛进行的早期血清学调查作比较。发现鹿流行性出血病（EHD）的阳性抗体滴度为8%，蓝舌病（BT）为1%，裂谷热（RVF）为49%。然而，在测试的100只动物中，没有检测到针对非洲马瘟（AHS）的抗体水平。这些数值与1987年至1997年在KNP对白犀牛进行的调查中测得的数值形成鲜明对比（AHS为60%，EHD为30%，BT为37%，RVF为0%）。同一地理位置的白犀牛中媒介传播病毒感染率似乎随时间变化，可能对监测生态系统中病原体的存在很重要。
