Abstract

Spirocerca lupi is a parasitic nematode that causes spirocercosis predominantly in domestic dogs. Spirocerca lupi nematode samples were collected from four regions around South Africa and analyzed to compare the genetic diversity among the regions. A total of 56 S. lupi nematodes were obtained by necropsy from domestic dogs and wild black-backed jackals (Canis mesomelas). Sixteen different haplotypes of cox1 were identified some of which are shared between regions as well as with black-backed jackal. The genetic similarity between S. lupi in domestic dogs and black-backed jackals indicates transmission between these canid species and may have potential conservation implications.

摘要

狼旋尾线虫是一种主要感染家犬的寄生线虫，可导致旋尾线虫病。从南非周边四个地区采集了狼旋尾线虫样本，并进行分析以比较各地区之间的遗传多样性。通过对家犬和野生黑背胡狼（Canis mesomelas）进行尸检，共获得了56条狼旋尾线虫。鉴定出了16种不同的细胞色素氧化酶亚基1（cox1）单倍型，其中一些在不同地区以及与黑背胡狼之间共享。家犬体内的狼旋尾线虫与黑背胡狼体内的狼旋尾线虫之间的遗传相似性表明这些犬科物种之间存在传播，并且可能具有潜在的保护意义。
