The diversity and importance of Echinococcus species in domesticated animals in Saudi Arabia are poorly understood. In this study, 108 singular (hydatid) cysts were collected from goats (n = 25), sheep (n = 56) and camels (n = 27). DNA was extracted from the protoscoleces of individual fertile cysts and used for polymerase chain reaction (PCR) amplification of mitochondrial subunit 1 of the cytochrome c oxidase 1 (cox1) gene. Amplicon sequencing results revealed the presence of Echinococcus granulosus sensustricto (s.s.) (genotypes G1-G3) in 16 of the17 sheep cysts and 2 of the 27 camel cysts.of these samples, 18 (2 camel and 16 sheep) were divided into genotypes G1, G2, and G3.
在沙特阿拉伯,家畜中细粒棘球绦虫种类的多样性和重要性还不太了解。在这项研究中,从山羊(n=25)、绵羊(n=56)和骆驼(n=27)中采集了 108 个单一(包虫)囊肿。从单个有活力的囊肿的原头蚴中提取 DNA,并用于聚合酶链反应(PCR)扩增细胞色素 c 氧化酶 1(cox1)基因的线粒体亚单位 1。扩增子测序结果表明,在 17 个绵羊囊肿中的 16 个和 27 个骆驼囊肿中的 2 个中存在细粒棘球蚴(s.s.)(基因型 G1-G3)。在这些样本中,18 个(2 个骆驼和 16 个绵羊)被分为基因型 G1、G2 和 G3。
