2018—2022年山东省牛羊布鲁氏菌病监测数据分析

Analysis on Monitoring Data of Bovine and Ovine Brucellosis in Shandong Province from 2018 to 2022

为了解近年来山东省牛羊布鲁氏菌病防控效果,对山东省2018—2022年布鲁氏菌病监测数据进行了时间、空间和群间统计分析。结果显示:2018—2022年山东省牛羊布鲁氏菌病个体阳性率分别为0.25%、0.29%、0.20%、0.18%、0.41%,场群阳性率分别为1.08%、1.01%、0.96%、1.14%、1.52%;奶牛、肉牛、羊的布鲁氏菌病个体阳性率分别为0.17%、0.02%、0.39%,场群阳性率分别为2.03%、1.59%、0.44%,羊的个体阳性率和场群阳性率均显著高于牛(P<0.001);泰安市、枣庄市、淄博市的布鲁氏菌病个体阳性率较高,枣庄市、德州市、淄博市的场群阳性率较高,各市间差异具有统计学意义(P<0.001)。结果说明:山东省牛羊布鲁氏菌病处于低水平流行态势,防控效果较好,但是羊群中尤其是中西部地区仍有布鲁氏菌病散发风险,需要加强风险监测,以确保畜牧业健康发展。

In order to investigate the control effect of bovine and ovine brucellosis in Shandong Province in recent years,the monitoring data collected from 2018 to 2022 in the province were analyzed in terms of time,space and population.The results showed that the individual positive rates of bovine and ovine brucellosis were 0.25%,0.29%,0.20%,0.18%and 0.41%,respectively,and the ones at group/farm level were 1.08%,1.01%,0.96%,1.14%and 1.52%,respectively;the individual positive rates in cows,beef cattle and sheep were 0.17%,0.02%and 0.39%,respectively,and the ones at group/farm level were 2.03%,1.59%and 0.44%,respectively;the two rates were obviously higher in sheep than those in cattle(P<0.001);the individual positive rate of brucellosis was higher in Tai'an,Zaozhuang and Zibo cities,and the one at group/farm level was higher in Zaozhuang,Dezhou and Zibo cities,with a statistically significant difference among cities(P<0.001).In conclusion,bovine and ovine brucellosis in the province was prevalent at a low level,well prevented and controlled,although there was still a risk of sporadic occurrence in sheep population,especially in the central and western regions of the province,which should be further monitored to safeguard healthy development of livestock industry.
