Ten soldiers of the Korean Army were found to have F. seoulensis ova in their faeces. These men were treated with praziquantel and the worms passed after purging were successfully collected in one case: 59 F. seoulensis, 68 Metagonimus and 2 Stellantchasmus falcatus were collected. 2 men were also infected with Clonorchis sinensis. All the cases of fibricoliasis had eaten raw or undercooked snake meat or frogs during survival training. All were egg-negative 2-6 months after treatment.
