| 目的 应用超声诊断普查方式了解新疆巴音布鲁克奎克乌苏达板地区绵羊感染肝囊型包虫病情况。方法 2014年7月在巴音布鲁克奎克乌苏达板地区采用现患筛查方法,以肝包虫病超声声像图征象为诊断标准,现场调查绵羊肝囊型包虫患病情况。以羊齿龄分组,分别计算不同齿龄羊肝囊型包虫病感染率,并分析齿龄与感染率间的相关关系。结果 巴音布鲁克奎克乌苏达板地区放牧绵羊肝囊型包虫病的总感染率为36.9%.其中非钙化型肝囊型包虫病的总感染率为7.3%;钙化型肝囊型包虫的总感染率为29.6%.按绵羊齿龄分组后,①非钙化型肝囊型包虫病感染率1～岁齿龄组为1.2%、2～岁齿龄组为1.4%、3～岁齿龄组为14.0%、4～岁齿龄组为10.0%、5～岁齿龄组为15.6%、>6岁齿龄组为4.2%;②钙化型肝囊型包虫病感染率,各岁齿龄组分别为9.9%、16.2%、31.6%、47.8%、42.2%和41.7%,其中以1～岁齿龄组肝囊型包虫病感染率较低,>3岁齿龄绵羊肝囊型包虫病感染率明显增加;③绵羊肝囊型包虫病感染率和齿龄间存在正相关关系(r=0.372,R2=0.107,F=44.176,P=0.000),即随齿龄增长,肝囊型包虫病的感染率增加。结论 新疆巴音布鲁克奎克乌苏达板地区属肝囊型包虫病的高流行区。绵羊肝囊型包虫病感染从羊只幼龄开始出现,3～4岁齿龄时呈高发状态,幼龄羊应为预防绵羊肝囊型包虫病的重点。 |

| Objective To investigate the prevalence rate of ovine hepatic cystic echinococcosis (HCE) in sheep in Quaker Wusu area of Bayinbuluke of Xinjiang by ultrasonography and provide evidence for the prevention and control of HCE in sheep. Methods The prevalence screening of HCE in sheep was conducted based on ultrasound images in this area in July 2014. The sheep were divided into different groups by dental age to calculate the age specific prevalence rate of HCE and analyzed the correlation between the dental age and the prevalence rate. Results The total prevalence rate of HCE in sheep in this area was 36.9%. The prevalence rates of none-calcified HCE and calcified HCE were 7.3% and 29.6%,respectively. The prevalence rates of none-calcified HCE in different age groups were 1.2%(1-2 years old),1.4%(2-3 years old),14.0%(3-4 years old),10.0% (4-5 years old),15.6%(5-6 years old) and 4.2%(>6 years old) respectively. The prevalence rate of calcified HCE in different age groups were 9.9%(1-2 years old),16.2%(2-3 years old),31.6%(3-4 years old),47.8%(4-5 years old),42.2%(5-6 years old) and 41.7%(>6 years old) respectively. The prevalence rate of HCE in 1-2 years old group was lower than those in other groups,the prevalence rate of HCE in age groups >3 years increased significantly. There was positive correlation between the prevalence rate of HCE and dental age(r=0.372,R2=0.107,F=44.176,P=0.000). Conclusion HCE is highly endemic in Quaker Wusu area. The prevalence rate of HCE is low in sheep with young age and high in sheep aged 3-4 years. It is necessary to conduct early prevention of HCE in sheep in this area. |
