摘要
本研究于2013年1月至2015年10月采集3个鹤类饲养单位81份丹顶鹤样品、37种245份周边环境的其他鸟类样品,3个单位4种昆虫3 948只进行圈养丹顶鹤血变原虫的流行调查研究。采用瑞-姬氏涂片染色镜检以及套式PCR检测血孢子虫cytb基因、测序分析比对等方法调查各地丹顶鹤血变原虫的流行情况。丹顶鹤样品中共检出血变原虫进化支2种,检出率为19.75%,其他鸟类样品的检出率为0.41%,吸血昆虫样品的检出率为1.05%;扎龙、向海的丹顶鹤和环境吸血昆虫、北京的鹈鹕感染同一个血变原虫进化支,并且该进化支是各类动物中检出率最高的血变原虫进化支。
In the present study,81 samples of red crowned crane, 245 samples of 37 species of environment birds, and 3 948 samples of 4 species of environment blood sucking insects were collected in 3 crane breeding bases, including Beijing zoo, Xianghai National Nature Reserve, and Zhalong National Nature Reserve.To investigate the prevalence of Haemoproteus, the blood smears were stained with Wright-Giemsa and observed under an optical microscope,cytb gene was amplified by nested PCR,sequenced, and analyzed by BLAST.The results showed that 2 Haemoproteus lineages were found in red crowned crane samples with the relevance ratio of 19.75%; the relevance ratio of environment birds was 0.41%, and environment blood sucking insects was 1.05% Further, a same lineage was detected in red crowned crane, blood sucking insects were in Xianghai and Zhalong, and pelican was in Beijing.The Haemoproteus lineage has the highest relevance ratio among all kinds of animals.
