Cysticercus tenuicollis is the metacestode of canine tapeworm Taenia hydatigena, which has been reported in domestic and wild ruminants and is causing veterinary and economic losses in the meat industry. This study was conducted to determine the sequence variation in the mitochondrial cytochrome c oxidase subunit 1 (coxl) gene in 20 isolates of T. hydatigena metacestodes (cysticercus tenuicollis) collected from northern West Bank in Palestine. Nine haplotypes were detected, with one prevailing (55%). The total haplotype diversity (0.705) and the total nucleotide diversity (0.0045) displayed low genetic diversity among our isolates. Haplotype analysis showed a star-shaped network with a centrally positioned common haplotype. The Tajima's D, and Fu and Li's statistics in cysticercus tenuicollis population of this region showed a negative value, indicating deviations from neutrality and both suggested recent population expansion for the population. The findings of this study would greatly help to implement control and preventive measures for T. hydatigena larvae infection in Palestine.
细颈囊尾蚴是犬绦虫泡状带绦虫的中绦期幼虫，已在家养和野生反刍动物中被报道，并且在肉类行业中造成兽医和经济损失。本研究旨在确定从巴勒斯坦约旦河西岸北部采集的20株泡状带绦虫中绦期幼虫（细颈囊尾蚴）线粒体细胞色素c氧化酶亚基1（cox1）基因的序列变异。检测到9种单倍型，其中一种占主导（55%）。我们分离株中的总单倍型多样性（0.705）和总核苷酸多样性（0.0045）显示出较低的遗传多样性。单倍型分析显示出一个以中央位置的常见单倍型为中心的星形网络。该地区细颈囊尾蚴群体的Tajima's D以及Fu和Li统计值均为负值，表明偏离中性，两者都表明该群体近期出现了种群扩张。本研究结果将极大地有助于在巴勒斯坦实施泡状带绦虫幼虫感染的控制和预防措施。
