北京及周边地区猛禽血液寄生虫的感染率与多样性

摘要

In 2014 and 2015,the infection rates and lineage diversity of avian blood parasites were surveyed in the raptors in/around Beijing.Based on nest PCR examination,only 7.94％ of the raptors (n =126) were infected.A total of 7 lineages were identified by DNA sequencing of Cyt b and phylogenetic analysis.Comparing to MalAvi database,3 Haemoproteus lineages were newly reported and 2 lineages were first discovered in Strigiformes.%利用分子检测方法对2014-2015年北京及周边地区3目20种126只猛禽血液寄生虫的感染率和多样性进行调查.通过对猛禽血液寄生虫线粒体Cyt b基因的测序和系统发生分析,发现猛禽血液寄生虫的感染率较低(7.94％).通过与MalAvi数据库比对,共鉴定了7个谱系支,其中3个为新发现的血液变形虫属Haemoproteus谱系支,2个为首次在鸮形目Strigiformes中发现的谱系支.
