From October 2015 to August 2018, tapeworm proglottids were obtained from 10 patients who were residents of Daegu and Gyeongbuk provinces and had a history of raw beef consumption. Most of them had no overseas travel experience. The gravid proglottids obtained from the 10 cases had 15-20 lateral uterine branches. A part of internal transcribed spacer 1 (ITS1) DNA of the 10 cases, amplified by polymerase chain reaction (PCR) and digested with AleI restriction enzyme, produced the same band pattern of Taenia saginata, which differentiated from T. asiatica and T. solium. Sequences of ITS1 and cytochrome c oxidase subunit 1 (cox1) showed higher homology to T. saginata than to T. asiatica and T. solium. Collectively, these 10 cases were identified as T. saginata human infections. As taeniasis is one of the important parasitic diseases in humans, it is necessary to maintain hygienic conditions during livestock farming to avoid public health concerns.
2015年10月至2018年8月，从大邱和庆尚北道的10名居民患者身上获取了绦虫节片，这些患者均有食用生牛肉的历史。他们大多数没有海外旅行经历。从这10例病例中获取的妊娠节片有15 - 20个子宫侧支。通过聚合酶链反应（PCR）扩增并经AleI限制酶消化的这10例病例的部分内转录间隔区1（ITS1）DNA，产生了与牛带绦虫相同的条带模式，与亚洲带绦虫和猪带绦虫相区别。ITS1和细胞色素c氧化酶亚基1（cox1）的序列显示与牛带绦虫的同源性高于亚洲带绦虫和猪带绦虫。总体而言，这10例病例被鉴定为牛带绦虫人体感染。由于绦虫病是人类重要的寄生虫病之一，在畜牧业养殖过程中保持卫生条件以避免公共卫生问题很有必要。
