Abstract

A total of 118 sera were collected during 2016 from two groups of dromedaries from Kebili and Medenine governorates in the south of Tunisia. The aim of this study was to provide the first serological investigation of four emerging vector-borne diseases in two groups of dromedaries in Tunisia. Sera were tested by ELISA and serum neutralisation test to identify West Nile virus (WNV), bluetongue virus (BTV), epizootic haemorrhagic disease virus (EHDV) and Rift Valley fever virus (RVFV). In the first group, the seroprevalence for BTV was 4.6%, while in the second group, it was 25.8% for WNV and 9.7% for BTV. Only serotype 1 was detected for BTV in the two groups. No evidence for circulation of RVF and EHD viruses was revealed. Results indicated that dromedaries can be infected with BTV and WNV, suggesting that this species might play a significant role in the epizootiology of these viral diseases in Tunisia and neighbouring countries.

突尼斯单峰骆驼中新出现的媒介传播疾病:西尼罗病、蓝舌病、动物流行性出血性疾病和裂谷热。

2016年期间，从突尼斯南部Kebili省和Medenine省的两组单峰骆驼中共采集了118份血清。这项研究的目的是对突尼斯两组单峰骆驼中出现的四种新媒介传播疾病进行首次血清学调查。采用ELISA和血清中和试验检测血清中西尼罗病毒(WNV)、蓝舌病病毒(BTV)、流行性出血病病毒(EHDV)和裂谷热病毒(RVFV)。第一组血清BTV阳性率为4.6%，第二组血清WNV阳性率为25.8%，BTV阳性率为9.7%。两组均检出血清1型BTV。没有发现裂谷热和EHD病毒传播的证据。结果表明，单峰骆驼可感染BTV和WNV，提示该物种可能在突尼斯及其邻国这两种病毒性疾病的流行病学中发挥重要作用。
