An epidemiologic survey along the several sites of southern coastal areas of Korean peninsula was performed to know the infection status of Parvatrema spp. metacercariae in Tapes philippinarum. The clams were purchased from 13 coastal areas in Kyongsangnam-do and Chollanam-do, in September, 1990. Each of them was digested with pepsin-HCl solution and examined under a stereomicroscope for the recovery of metacercariae. A total of 232 (77.3%) out of 300 examined clams were proved to have 1 to 273 Parvatrema spp. metacercariae (54.7 in average). None of the clams from Samsan-myon Kosong-gun and Dolsan-up. Yochon-gun was infected with metacercariae. However, all of the clams from Yonghyon-myon, Sachon-gun, Dohwa-myon, Kohung-gun, Ahllyang-myon, Changhung-gun and Chiryang-myon. Kangjin gun were infected with average 71, 31, 80 and 42 metacercariae respectively. Of the clams from Kohyon-myon. Namhae-gun. Doam-myon, Kangjin-gun and Kusan-myon, Uichang-gun examined, 97.5%, 95.0% and 90.0% were infected with about 117, 76 and 28 metacercariae. In other 4 surveyed areas. Seolchon-myon, Namhae-gun. Hwayang myon, Yochon-gun, Byollyang-myon, Sungju-gun and Bukpyong-myon. Haenam-gun, 55.0%-80.0% of clams were positive, and their average intensity of infection ranged from 6 to 25 metacercariae. From thse results, it was confirmed that Tapes philippinarum from southern coastal areas of Korea are highly infected by Parvatrema spp. metacercariae.
为了解菲律宾蛤仔中微小膜壳绦虫囊蚴的感染状况，在朝鲜半岛南部沿海的几个地点进行了一项流行病学调查。1990年9月，从庆尚南道和全罗南道的13个沿海地区购买了蛤仔。将每只蛤仔用胃蛋白酶 - 盐酸溶液消化，并在实体显微镜下检查以回收囊蚴。在300只检查的蛤仔中，共有232只（77.3%）被证明含有1至273个微小膜壳绦虫囊蚴（平均54.7个）。固城郡三山里和海南郡突山邑的蛤仔均未感染囊蚴。然而，泗川郡龙玄面、统营郡、巨济郡多花面、高兴郡、咸安郡阿阳面、长兴郡和晋州市池阳面的所有蛤仔均被感染，平均分别有71、31、80和42个囊蚴。在南海郡可玄面、海南郡道岩面、康津郡、固城郡草山面和蔚珍郡的蛤仔中，97.5%、95.0%和90.0%的蛤仔被感染，分别约有117、76和28个囊蚴。在其他4个调查地区，即海南郡雪川面、海南郡、咸阳郡华阳面、海南郡药川面、莞岛郡、咸安郡笔梁面、星州郡和海南郡北坪面，55.0% - 80.0%的蛤仔呈阳性，其平均感染强度为6至25个囊蚴。从这些结果可以确认，韩国南部沿海地区的菲律宾蛤仔受到微小膜壳绦虫囊蚴的高度感染。
