【摘要】：目的调查新疆维吾尔自治区家(牧)犬、啮齿类动物和家畜感染棘球绦虫或棘球蚴现状。方法2012年8月至2013年9月根据新疆维吾尔自治区棘球蚴病流行情况调查方案,选择有多房棘球蚴病流行的阿勒泰山、塔额盆地、伊犁河谷、北部天山和中部天山等5地的26个县(市)366个行政村作为调查点,采集各村家(牧)犬粪,ELISA检测犬粪棘球绦虫抗原情况,用触摸和肉眼观察啮齿动物和屠宰场家畜(绵羊、马、牦牛、黄牛和山羊)的棘球蚴包囊情况。犬粪抗原阳性率和棘球蚴感染率比较均采用卡方检验。结果共采集家(牧)犬粪8 493份,ELISA检测结果显示,粪抗原阳性率为2.63%(223/8 493),其中塔额盆地阳性率为4.69%(74/1 600),高于伊犁河谷(2.52%,66/2 615)、阿勒泰山(2.14%,50/2 341)、中部天山(2.08%,27/1 298)和北部天山(0.94%,6/639)(χ~2=13.65~18.01,P0.05)。家畜棘球蚴病患病检出率为6.18%(1 616/26 170),除牦牛和马未检出棘球蚴包囊外,其余均有检出。其中绵羊患病检出率为6.47%(1 550/23 943),高于黄牛(3.18%,30/943)和山羊(2.89%,36/1 247)(χ~2=25.85~16.54,P0.05)。中部天山家畜患病检出率最高,为18.04%(545/3 021),高于伊犁河谷(6.44%,305/7 312)、北部天山(4.17%,65/2 010)、塔额盆地(3.59%,239/6 652)和阿勒泰山(3.23%,462/7 175)(χ~2=321.46~248.35,P0.05)。棘球蚴寄生在肝、肺、肝+肺和其他脏器的比例为116∶12∶5∶1。共采集并剖检啮齿动物46种25 400只,其中20种374只啮齿动物检出棘球蚴囊,患病检出率为1.47%。除北部天山的啮齿类动物未检出棘球蚴外,伊犁河谷的患病检出率(3.94%,322/8 120)高于中部天山(0.55%,18/3 260)、塔额盆地(0.55%,28/5 076)和阿勒泰山(0.09%,6/6 942)(χ~2=93.50~264.36,P0.05)。结论新疆家(牧)犬粪棘球绦虫抗原阳性率以及啮齿动物和家畜棘球蚴病患病检出率仍较高。
[Abstract]:Objective to investigate the infection status of Echinococcus Echinococcus or Echinococcus in domestic (animal husbandry) dogs, rodents and domestic animals in Xinjiang Uygur Autonomous region. Methods from August 2012 to September 2013, we investigated the prevalence of echinococcosis in Xinjiang Uygur Autonomous region. Select 26 counties (366 administrative villages) in 5 places, such as Altai Mountain, Tawar Basin, Yili River Valley, Northern Tianshan and Central Tianshan, where multilocular echinococcosis is prevalent. Echinococcus canis antigen was detected by Elisa, and rodents and slaughterhouse livestock (sheep, horse, yak) were observed with touch and naked eye. The positive rate of fecal antigen in dogs and the infection rate of echinococcus were compared by chi-square test. Results A total of 8 493 faeces from domestic (grazing) dogs were detected by Elisa. The positive rate of fecal antigen was 2.63 / 223 / 8 493, of which the positive rate in the Tap forehead basin was 4.69 / 74 / 1600, which was higher than that in the Yili Valley 2.52 / 266 / 2615 / 2 615, in Altay 2.14 / 50 / 2341, in the middle Tianshan 2.08 / 27 / 12 298) and in the northern Tianshan 0.94% / 6639 (蠂 213.6518.01 / 01 P 0.05). The incidence rate of echinococcosis in domestic animals was 6.1818 616/26 170, except for the yak and horse that had not been tested for hydatid cyst. The detection rate of sheep was 6.47 (1 550/23 943), which was higher than that of yellow cattle (3.18% 30 / 943) and goat (2.89% 36 / 1 247) (蠂 ~ (2 +) 25. 85% 16. 54% P 0.05). The highest incidence rate was found in domestic animals in the central Tianshan Mountains. It was 18.04545 / 3,021, higher than that in the Yili River Valley 6.4445 / 3057.312m, in the north Tianshan 4.1765 / 2010m, in the forehead basin 3.59239r6652) and in Altaishan 3.232R / 7,1755.The proportion of echinococcus parasitic on the liver, lungs, lungs and other organs was 11612 51.The ratio of 46 species to 25,400 rodents was collected and dissected, and the proportion of echinococci parasitized on the liver, lungs, lungs and other organs was 1161251.The ratio of the parasitic cercariae in the liver, lungs, lungs and other organs was 1161251.46 species of odontoids were collected and examined. Of the 374 rodents of 20 species, hydatid sac was detected, and the detection rate was 1.47.Echinococcus was not detected in rodents of northern Tianshan, except for the rodents in northern Tianshan. The detection rate of the disease in Yili River Valley was 3.94 / 322 / 8.120, which was higher than that in the middle Tianshan (0.55 / 3 260), and in the Tapa Basin (0.55 / 50 / 5076) and in Altaishan (0.09 / 6 / 6942). Conclusion the positive rate of Echinococcus faecalis antigen and the incidence of rhinococcosis in rodents and domestic animals in Xinjiang are still higher than those in the middle Tianshan (3 22 / 8 120) and the incidence of Echinococcus rhinoides in rodents and domestic animals is still higher than that in the middle part of Tianshan Mountain (3 22 / 8 120) and the incidence of Echinococcus rhinoides in rodents and domestic animals is still higher.
