摘要:

  【摘要】  目的 调查塔里木盆地荒漠型黑热病的保存宿主。方法 开展动物与传播媒介及其环境的调查。冬季采集动物样品,用ELISA筛选抗体阳性动物;接种草原兔尾鼠和液体培养基培养分离利什曼原虫;分子生物学方法测定从当地黑热病患者、动物和传播媒介分离出的利什曼原虫特定基因序列。结果 塔里木兔和家犬有抗利什曼原虫抗体;从44只抗体阳性塔里木兔中分离出3株利什曼原虫;塔里木兔、黑热病患者和吴氏白蛉分离出的利什曼原虫测定的NAGT核基因序列相同,与GenBank注册的婴儿利什曼原虫AF205934一致。结论 塔里木兔是塔里木盆地荒漠型黑热病的野生宿主之一。

Abstract:

  【Abstract】 Objective  To survey reservoir hosts of desert-type kala-azar in Tarim Basin. Methods Collect animal samples in winter, and screen the samples which antibody were positive by ELISA. Leishmania was isolated by Lagurus lagurus inoculation and tissue culture. The specific gene sequences of Leishmania infantum isolated from kala?azar patients, Yarkend hare and Phlebotomus wui were amplified by molecular biological technology. Results  There was Leishmania antibodies in Yarkend hare and Canis familiaris, and 3 strains of Leishmania were isolated from 44 of Yarkend hare which antibodies were positive. The NAGT gene sequences amplified from hares (3 strains), patients (1 strain) and vectors (6 strains) were same, according with the sequence of  L.infantum (AF205934)  from GenBank.  Conclusion It suggests that yarkend hare is one of the primal host of desert-type kala-azar in Tarim Basin.
