目的探究新疆阿拉山口艾比湖湿地蜱的种类、季节消长规律及其分子特征,为阿拉山口艾比湖湿地蜱的分类研究以及蜱传疾病的科学防控提供依据。方法采用布旗法和动物体表搜集法在阿拉山口禾角克边防连、乌兰达布森管护站、艾比湖湿地国家自然保护区石头房子3个采样点,自2014年4-8月连续采集蜱,对采集蜱种进行形态学鉴定,并选取代表蜱种进行线粒体16S r DNA序列扩增与测序分析。结果共采集蜱434只,其中游离蜱392只,寄生蜱42只;经体视显微镜形态学鉴定,采集样本为1科4属(扇头蜱属、璃眼蜱属、革蜱属、血蜱属)7种(亚洲璃眼蜱、边缘革蜱、银盾革蜱、血红扇头蜱、图兰扇头蜱、囊形扇头蜱、短垫血蜱);艾比湖湿地优势蜱种为亚洲璃眼蜱、边缘革蜱;蜱活动高峰集中在5-6月,革蜱属最高峰出现在5月,亚洲璃眼蜱为6月;线粒体16S r DNA PCR测序比对结果显示,边缘革蜱与新疆石河子注册的KF547986同源性在96%-100%,亚洲璃眼蜱与新疆伊犁注册的KF527439同源性在98%-99%,血红扇头蜱与以色列注册的KF219732同源性在93%-94%。结论首次在艾比湖湿地发现图兰扇头蜱和囊形扇头蜱;在国际上首次对短垫血蜱16S r DNA序列进行了分析和报道,该蜱与美国Haemaphysalis cretica同源性最高(91.0%);艾比湖湿地地区边缘革蜱、亚洲璃眼蜱、血红扇头蜱16S r DNA存在多样性,来自不同蜱种遗传分支。
Due to various reasons, the inspection methods often need to be changed, and the detection reagents often need to be replaced. In this study, a comparative experiment was conducted between the ethanol-based and ether-based determination methods for oil content in imported wool. The determination results obtained from the two methods were treated as abscissa and ordinate respectively,and their linear relationship was analyzed. According to the linear regression analysis, the conversion equation of determination result between the two methods was obtained. In addition, the repeatability admissible error and reproducibility admissible error were established through analyzing the comparative experimental results by scientific software. This study will bring new ideas for further researches in this field, and provide reference for solving the similar problems in actual inspection work.
