Popis: We conducted an epidemiological survey to determine the status of heterophyid fluke infections among people residing along the Boseong River, Gokseong-gun, South Korea (= Korea) from October 2011 to February 2012. Fecal specimens were collected from 115 (male 51, female 64) people and examined for intestinal helminth eggs using the Kato-Katz thick smear technique. The eggs of Metagonimus yokogawai together with other Metagonimus spp. were detected in 28 (24.3%) cases. Eleven egg positive people were treated with 10 mg/kg praziquantel followed by MgSO 4 purging in order to recover the adult flukes. Whole consecutive diarrheic stools were collected individually 4–5 times. Adult flukes recovered were 66,499 specimens (6045.4/positive case) of M. yokogawai , 343 (38.1) of Metagonimus miyatai , 3293 (299.4) of Metagonimus takahashii , 81 (20.3) of Heterophyes nocens , 6 (3.0) of Heterophyopsis continua , and 1 (1.0) of Stictodora fuscata . The results indicated that the surveyed area is a highly endemic area of metagonimiasis (three Metagonimus species) with low-grade mixed infections of 3 other heterophyid flukes. The infected people experienced variable degrees of gastrointestinal discomfort and indigestion. They consumed raw freshwater and brackish water fish, including sweetfish and mullets. It is strongly recommended that people residing in the survey area avoid eating raw fish to prevent M. yokogawai and other heterophyid infections.
