Cystic echinococcosis is a zoonotic disease and the second most common foodborne parasitic infection worldwide. The aim of the present study was to investigate genetic variations in G1 and G3 genotypes of Echinococcus granulosus sensu stricto and determine the morphological differences between two genotypes. In total, 119 cystic samples were collected from 48 cattle and 71 sheep in slaughterhouses in four cities in three geographical regions of Turkey regions (Ankara, Central Anatolio region; Ordu, Black Sea region; and Adana, Mersin, Mediterranean region). For molecular characterization of the G1 and G3 genotypes, two gene regions (the complete mt-cox1 gene sequence and partial mt-nad5 gene sequence) were amplified. Haplotype analysis was conducted to determine the nucleotide differences between the complete sequences of the mt-cox1 gene for 47 samples. In addition, morphological parameters in protoscoleces of fertile cysts were measured to determine the relationship between the genotypes and morphometry. According to the obtained genotype and morphometry results, there were no statistically significant differences between the genotypes in terms of the number of hooks, total lengths of large and small hooks, blade lengths of large and small hooks, and widths of small hooks, although there was a statistically significant difference in large hook width (p > 0.05).

牛和绵羊囊性棘球ech虫病分离株的分子和形态特征比较及单倍型分析。

囊性棘球co病是一种人畜共患疾病，是全世界第二大最常见的食源性寄生虫感染。本研究的目的是调查细粒棘球EG1和G3基因型的遗传变异，并确定两种基因型之间的形态差异。在土耳其三个地理区域（中部安纳托里奥地区安卡拉；黑海地区奥杜；地中海地区梅尔辛阿达纳）的四个城市的屠宰场中，总共从48头牛和71只绵羊的粪便中收集了119个囊性样品。为了对G1和G3基因型进行分子表征，扩增了两个基因区域（完整的mt-cox1基因序列和部分mt-nad5基因序列）。进行了单倍型分析，以确定47个样品的mt-cox1基因完整序列之间的核苷酸差异。另外，测量可育囊肿的原壁细胞的形态学参数，以确定基因型与形态学之间的关系。根据获得的基因型和形态学结果，尽管在一定程度上，这些基因型在钩数量，大和小钩的总长度，大和小钩的叶片长度以及小钩的宽度方面没有统计学上的显着差异。大钩宽度有统计学差异（p> 0.05）。
