摘要
目的非洲猪瘟病毒可引起家猪的出血性致死性疫病,其一旦发生,很难根治。对此病传入我国的危险性进行评价,预测其生物传播媒介在我国的潜在分布区,对于防控工作具有重要意义。方法运用适生性分析软件Climex预测软蜱在我国的潜在分布区。结果根据软蜱的生物学数据和软件自带的模板参数,得出软蜱的调试参数;经Climex分析,软蜱在我国云南、贵州、四川东部、重庆、陕西南部、湖南、湖北、江西东北部、安徽、河南、浙江、江苏、山东、河北南部等地的生态气候指数值>20,为高适宜潜在发生区。结论我国部分地区可能成为非洲猪瘟的自然疫源地。提示应将这些地区列为监测和防控的重点。
Objective This study aims to evaluate the risk for the introduction of African swine fever virus to China and to predict the potential distribution of the vectors,providing the basis for development of prevention and control strategies.Methods The adaptability analysis software,Climex,was employed to predict the potential distribution of soft ticks in China.Results The parameter setting was derived from the biological data of soft ticks and the default template parameters of Climex.The analysis revealed that the ecoclimatic indexes of soft ticks in such places as Yunnan,Guizhou,Eastern Sichuan,Chongqing,Southern Shaanxi,Hunan,Hubei,Northeastern Jiangxi,Anhui,Henan,Zhejiang,Jiangsu,Shandong and Hebei were greater than 20;these locations would be the highly suitable,potential habitats for soft ticks in China.Conclusion Some areas in China may be the natural foci of African swine fever,suggesting that the future monitoring and control should be focused on these regions.
