摘要
【目的】了解广西家养反刍动物蓝舌病毒(BTV)的感染情况,为防控广西蓝舌病(BT)提供参考依据。【方法】采用琼脂免疫扩散试验(AGID)对采自广西境内的2535份山羊血清和496份水牛血清进行BTV抗体检测,并对地理、气候因素与BTV区域分布情况进行分析。【结果】广西山羊和水牛的总BTV抗体阳性率分别为36.53%和43.55%,且以南宁市的山羊、水牛BTV抗体阳性率最高,分别为78.13%和85.71%。广西家养反刍动物BTV抗体阳性率呈北低南高,高海拔地区BTV抗体阳性率低于低海拔地区,气温较高的南亚热带及北热带的BTV抗体阳性率高于气温较低的中亚热带,降水充沛的东部地区的BTV抗体阳性率高于降水较少的中部和西部地区。【结论】广西家养反刍动物普遍存在BTV感染,且分布受到纬度、海拔、气温与降雨量等地理、气候因素的影响。
[Objective]This study aimed to investigate the widespread epidemic of bluetongue virus (BTV) in rumi- nants of Guangxi in order to provide theoretical references for the prevention and control of bluetongue disease (BT). [Method]The AGID test was used to detect the antibodies of BTV in 2535 goat sera and 496 buffalo sera, of which both groups were collections from Guangxi province. The correlation between the climate, geography factors, and seroprevalence distribution were also analyzed. [Result]The seroprevalence in goats and buffaloes were 36.53% and 43.55%, respective- ly; furthermore, the goats and buffaloes of Nanning City exhibited the highest seroprevalence, which accounted for 78.13% and 85.71%, respectively. The seroprevalence of BTV antibody in ruminants of Southern Guangxi was higher than that of Northern Guangxi; consequently, the seroprevalence in low latitude areas was higher than high latitude areas, the sero- prevalence in south subtropical areas and north tropical areas with high temperature was higher than that in the central sub- tropical areas with low temperature, and the seroprevalence in east areas with plentiful rainfall was higher than that in the central areas and west areas with less rainfall. [ Conclusion ] BTV epidemic prevailed in Guangxi's domestic ruminants. The distribution of BTV in Guangxi was heavily influenced by geographic conditions and climate factors viz., latitudes, alti- tudes, temperatures, rainfall volumes, etc.
