Fascioliasis is a common human-animal disease that is reported in most parts of the world. Fascioliasis is also prevalent in different provinces of Iran. Since it has done no study on the excretory/secretory and somatic immunogenic antigens profiles of adult in Iran, the present study was performed on the collected from Mazandaran province. For this purpose, the worm was isolated from the liver of infected sheep, then its excretory/secretory and somatic antigens were prepared from adult worms. The protein of the samples was measured by the Lowry method. Then, somatic and secretory excretions were examined by SDS-PAGE and the protein profile of the two substances was determined. To evaluate the immunogenicity, the somatic and secretory excretions antigens of were injected into white rabbits and after boosting, the blood serum of the rabbits was collected and then Western blotting was performed on them and the results were evaluated. According to the results of Western blotting, 11 somatic antigen bands with a molecular weight of 149, 122, 99, 85, 75, 65, 50, 46, 40, 37, 30 kDa and 12 protein bands of excretory/secretory antigens with molecular weights of 100, 82, 75, 70, 58, 55, 47, 40, 38, 37, 30,25 kDa were observed in adult that immunogenic, which appear to have a protective effect or can be used to prepare a diagnostic kit.
片形吸虫病是一种常见的人畜共患疾病,世界上大多数地区都有报道。片形吸虫病在伊朗的不同省份也很流行。由于伊朗尚未对成虫的排泄/分泌和体抗原免疫原性抗原谱进行研究,因此本研究在马赞达兰省采集的成虫上进行。为此,从感染绵羊的肝脏中分离出 ,然后从成虫中制备其排泄/分泌和体抗原。通过 Lowry 法测量样品中的蛋白质。然后,通过 SDS-PAGE 检查体和分泌排泄物,确定两种物质的蛋白质图谱。为了评估免疫原性,将 的体和分泌排泄抗原注入白兔体内,加强免疫后采集兔血清,然后对其进行 Western blot 分析,并评估结果。根据 Western blot 的结果,在 11 个分子量为 149、122、99、85、75、65、50、46、40、37、30 kDa 的体抗原带和分子量为 100、82、75、70、58、55、47、40、38、37、30、25 kDa 的 12 个分泌/分泌抗原带中观察到免疫原性,这些抗原似乎具有保护作用或可用于制备诊断试剂盒。
