【摘要】：藍(lán)舌病是由藍(lán)舌病病毒引起的一種傳染病,主要通過庫蠓叮咬反芻動(dòng)物,將其病原傳播流行。世界動(dòng)物衛(wèi)生組織將藍(lán)舌病歸類為A類動(dòng)物疫病,我國將其列為Ⅰ類動(dòng)物傳染病。庫蠓是國際公認(rèn)的藍(lán)舌病傳播媒介。目前,全世界的蠓科有125屬5360余種,只有其中一小部分具有傳播藍(lán)舌病病毒的能力。已知的吸血蠓有4屬1671種,我國已知的吸血蠓有3屬414種。近年來,全球氣候逐漸變暖,昆蟲活動(dòng)季節(jié)延長,使其繁殖時(shí)間延長,導(dǎo)致媒介數(shù)量越來越多。本次流行病學(xué)調(diào)查,自2013年6月-2015年2月,分別從內(nèi)蒙古阿拉善盟、烏海市、巴彥淖爾市、鄂爾多斯市、包頭市、呼和浩特市、烏蘭察布市、赤峰市、錫林郭勒盟、通遼市、興安盟11個(gè)盟市采集羊血清及抗凝血6199份,牛血清及抗凝血796份。其中,檢測出陽性羊2199只,感染率為35.47%；檢測出陽性牛93只,感染率為11.68%,羊的感染率高于牛的感染率。并且分別從動(dòng)物品種、年齡、性別、各方位等因素進(jìn)行比較。利用燈光誘捕法捕捉內(nèi)蒙古阿拉善盟、巴彥淖爾市、鄂爾多斯市、呼和浩特市、赤峰市、錫林郭勒盟、通遼市、興安盟8個(gè)盟市地區(qū)庫蠓共1132只,調(diào)查發(fā)現(xiàn)并鑒定內(nèi)蒙古地區(qū)庫蠓7種,分別為刺螫庫蠓(Culicoides punctatus)、環(huán)斑庫蠓(Culicoides circumscriptus)、蒙古庫蠓(Culicoides mongolensis)、異域庫蠓(Culicoides peregrines)、尖喙庫蠓(Culicoides oxystoma)、東方庫蠓(Culicoides orientalis)、琉球庫蠓(Culicoides actoni),其中刺螫庫蠓(Culicoides punctatus)332只,環(huán)斑庫蠓(Culicoides circumscriptus)276只,蒙古庫蠓(Culicoides mongolensis)231只,為該區(qū)優(yōu)勢種群。
[Abstract]:Bluetongue is an infectious disease caused by bluetongue virus, which is mainly transmitted by biting ruminants by Culicoides. The World Organization of Animal Health classifies bluetongue as a class A animal epidemic. Curicoides is an internationally recognized transmission vector of bluetongue disease. At present, there are more than 125 genera and 5360 species of Ceratopogonidae in the world. Only a small number of them have the ability to transmit bluetongue virus. There are 4 genera 1671 species of blood-sucking midges and 414 species of known blood sucking midges in China. In recent years, the global climate has become warmer and the insect activity season has been prolonged. This epidemiological survey, from June 2013 to February 2015, was conducted from Alashan League, Wuhai City, Bayannur City, Ordos City, Baotou City and Hohhot City, respectively. In Wulanchabu, Chifeng, Xilinguole, Tongliao and XingUNITA 11 league cities, 6199 sheep serum and anticoagulant blood samples were collected, and 796 bovine serum and anticoagulant blood samples were collected. Of these, 2,199 positive sheep were detected, with an infection rate of 35.47 and 93 positive cattle were detected. The infection rate of sheep was 11.68, and the infection rate of sheep was higher than that of cattle. The animal species, age, sex, orientation and other factors were compared. The light trapping method was used to capture Inner Mongolia Alashan League, Bayannur City, Ordos City, etc. There are 1132 Culicoides in Hohhot, Chifeng, Xilingol League, Tongliao City and XingUNITA City, and 7 species of Culicoides have been found and identified in Inner Mongolia. They are Culicoides punctatus, Culicoides circumscriptus, Culicoides mongolenensis, Culicoides peregrinesus, Culicoides oxystomia, Culicoides orientalisus, Culicoides actoniae, respectively. It is the dominant population in this area.
