新疆阿勒泰部分地区羊棘球蚴病（包虫病）流行情况调查

为评价新疆阿勒泰地区动物棘球蚴病(包虫病)防控效果，2022年采用ELISA方法，对阿勒泰地区阿勒泰市、福海县、富蕴县的羊群棘球蚴感染情况进行调查。结果显示：2022年共检测羊血清样品1 331份，检出阳性238份，总阳性率为17.9%，其中阿勒泰市、福海县、富蕴县阳性率分别为15.5%、18.6%、19.6%，不同县市间阳性率差异无统计学意义(P=0.255 8,P> 0.05)；第一季度阳性率(22.6%)较高，但同一县市不同季度间阳性率差异均无统计学意义(P> 0.05)；舍饲羊阳性率(9.6%)低于散养羊(23.5%)，差异有统计学意义(P <0.05);5岁以上年龄段阳性率较高(30.6%),1岁以内阳性率最低(6.8%)，同一县市不同年龄段阳性率差异均有统计学意义(P <0.05)。结果表明：本次调查的3个采样县市各季度均存在羊棘球蚴感染，区域和季度流行特征不明显，而饲养方式和年龄是影响感染强度的重要因素，散养羊和高年龄段羊感染相对较严重。结果提示，需加强对农牧民的棘球蚴病防控宣传，减少棘球蚴病对人类的威胁。本调查为进一步做好该地区棘球蚴病综合防控提...

宁夏2015年畜间包虫病流行病学调查

[目的]掌握宁夏部分地区畜间包虫病（棘球蚴病）流行情况,为包虫病的净化和综合防治提供依据。[方法] 2015年6—12月,对宁夏地区家畜和野生动物棘球蚴感染情况、农牧民对包虫病的知晓情况,采取问卷调查、实验室检测、实地走访座谈等方式进行调查。[结果]本次调查共抽查羊脏器2 092份,棘球蚴感染阳性率为3.35%;牛脏器1 749份,阳性率为0;检测羊血清样品2 080份,棘球蚴感染抗体阳性率为40.39%;检测犬粪样品4 620份,棘球绦虫感染阳性率为4.05%。调查3个县（区）的高原鼠兔、黄鼠等300只,均未发现有棘球蚴感染。调查还发现,农牧民对包虫病的知晓率参差不齐。[结论]针对宁夏地区畜间包虫病防治中存在的问题,建议加强犬只管理,积极开展犬的驱虫工作;加强牛羊屠宰管理;对新生母羔羊采用基因工程疫苗进行免疫;加强对农牧民的健康教育;加大政府的防治投入。

为了解宁夏吴忠市畜间包虫病流行范围及防治效果,科学规范指导下一阶段包虫病防治工作,2020年对吴忠市5个县(市、区)采用基本情况调查、实验室抽样检测等方法进行了畜间包虫病流行病学调查。共检测犬粪样品1 861份,犬细粒棘球绦虫感染阳性率为0.75%;抽检羊脏器4 027份,棘球蚴感染率为0.22%,有3个县区检出感染;检测牛脏器1 207份,棘球蚴感染率为0.17%,仅1个县检出感染。3个免疫试点县区中,同心县新生羔羊免疫率较低(36.18%),而羊棘球蚴感染率最高(0.66%)。统计分析显示,犬棘球蚴感染与牛羊感染呈正相关。结果表明,吴忠市畜间包虫病控制效果较好,但仍存在一定的棘球蚴感染,需要继续做好牛羊饲养管理和犬只驱虫,加强包虫病防治宣传,在重点地区大力推广包虫病疫苗免疫,逐步净化包虫病。本调查为该地区包虫病综合防治和净化提供了依据。     

内蒙古边境地区动物棘球绦虫感染状况调查报告

2008-2010年,在内蒙古自治区选择了6个边境旗(县),借助细粒棘球绦虫粪抗原抗体夹心酶联免疫吸附试验,调查了家(牧)犬棘球绦虫感染率;经屠宰场调查,检查了羊、牛棘球蚴感染水平;通过走访当地疾病防控中心,了解人感染包虫痛的基本情况.连续3年的调查结果显示,犬粪便抗原平均阳性率为13.16%,感染严重地区的犬粪便抗原阳性率最高为16.15%,以牧区的阳性率为最高,且越靠近边境地区感染越严重;羊、牛棘球蚴感染率平均为13.66%,感染严重地区的感染率最高为17.90%,平均感染强度达到了1.36个.调查表明,内蒙古边境地区棘球蚴病依然存在,且严重威胁着人类和家畜的健康,应引起重视.     

青海省棘球绦虫感染情况的调查及综合防治效果的检测

为全面掌握甘肃省棘球绦虫感染的流行状况及综合防治后的效果,在全省范围内对犬、牛、羊棘球绦虫感染情况以及防治效果进行了调查。结果表明,甘肃省犬、牛、羊棘球绦虫感染率较高,犬棘球绦虫、泡状带绦虫、多头绦虫、弓首蛔虫的感染率分别为61.76%、20.59%、2.94%和2.94%;牛、羊棘球蚴的感染率分别为47.89%和54.92%;牛、羊血清学阳性率分别平均为48.4%和65.7%。青海省地理环境和牧民生活习俗决定了棘球绦虫的生活史循环链复杂,致使动物的感染率较高,只有采取综合防治的措施才能有效控制。
