Abstract

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.

韩国10例猪带绦虫感染的内部转录间隔区1 rDNA分析

从2015年10月至2018年8月，从10名大邱和庆北地区居民中获得绦虫原虫，这些患者有生牛肉消费史。他们中的大多数人没有海外旅行的经历。10例孕先兆子均有15 ~ 20个子宫外侧分支。经聚合酶链反应(PCR)扩增和AleI酶切，10例猪带绦虫(Taenia saginata)与亚洲带绦虫(T. asiatica)和猪带绦虫(T. solium)同源。ITS1和细胞色素c氧化酶亚基1 (cox1)序列与柽柳的同源性高于与亚洲柽柳和柽柳的同源性。总的来说，这10例被确定为人类感染。由于带绦虫病是人类重要的寄生虫病之一，有必要在畜牧业中保持卫生条件，以避免公共卫生问题。
