羊源巴贝斯虫未定种甘肃敦煌株的发现
Discovery of an ovine Babesia sp. strain from sheep in Dunhuang City of Gansu Province
摘要
Abstract
Mixture of field-collected blood from 15 sheep in Dunhuang City was injected into a spleenectomized sheep.A large number of Babesia were present in the blood smeared on day 10 post-inoculation.The major morphological forms included paired piriform,single piriform,ring form and oval form.On day 12 post-inoculation,the body temperature and parasitemia of sheep reached 41.1 ℃ and 0.125% respectively and then decending.Genomic DNA was extracted from whole blood sterilely collected from the infected sheep.A 1 700 bp fragment was amplified by PCR using universal primers based on the 18 S rRNA gene.Then the target fragment was cloned and sequenced(GenBank accession number:HQ730762).Multiple sequence alignments were performed with those of other Babesia in GenBank.It shared the highest similarity with Babesia sp.Xinjiang,which was up to 99.8%.The present study discovered another epidemic focus of Babesia sp.Xinjiang in Dunhuang City of Gansu Province.关键词
