摘  要：
为了解新疆尉犁县库蠓体内携带病毒情况,从该县采集18 000只库蠓,50只为一组研磨后分别接种于BHK-21、C6/36、Vero细胞,盲传5代,一组样品使BHK-21出现CPE,先用5-氟尿核苷药敏试验鉴定为RNA病毒,之后用虫媒RNA病毒引物扩增,鉴定为甲病毒,疑似盖塔病毒,最后用中和试验、免疫电镜观察和盖塔病毒C基因特异性引物PCR等方法鉴定分离毒株为盖塔病毒。本研究首次从新疆库蠓体内分离到盖塔病毒,该毒株与2005年日本分离株相似性高达98%,推测可能是由于引进日本带病种公畜或精液有关,提示在进出口畜牧贸易活动中,应加强盖塔病毒的检疫工作。

摘  要：
In order to learn the situation of parasitic virus in Culicoidesin Yuli County,Xinjiang,a total of 18 000 Culicoides were collected from Yuli County and divided into 360 groups,with 50 Culicoides in each group.Then the Culicoides were ground and inoculated into BHK-21,C6/36 and Vero cells,respectively.After 5 generations of blind passage,one group of Culicoides made CPE arise in BHK-21.Then the isolated strain was firstly identified to be RNA viruses by drug sensitivity test(5-floxuridine).Secondly,the amplified primers were identified by arthropodborne RNA viruses and the result showed that the strain belongs to alphaviruses and is suspected to be Getah viruses.Finally,the isolated strain was determined to be Getah viruses by neutralization test,immunoelectron microscopic observation,PCR amplification of Getah virus Cgene-specific primer and other methods.In this study,Getah viruses were isolated from Xinjiang Culicoides for the first time and the virus strain presents a closest genetic relationship(98%)with the2005 Japanese isolated strain,for which the reason might be the introduction of Japanese breedingsires with the disease or their seminal fluid,suggesting that in the import and export trade activities of animal husbandry,quarantine inspection on Getah virus should be strengthened.
