[Cercarial chaetotaxy of a Korean strain of Clonorchis sinensis. Probable presence of this trematode in Africa]

The authors show a close morphological and chaetotaxical similarity between two strains of cercariae from naturally infested snails; the first strain, determinated as Clonorchis sinensis comes from Asia; the second one comes from Africa and its presence in this continent suggests that Clonorchis has been introduced there.
