    Abstract:
    Opisthorchis felineus (family Opisthorchiidae) is a parasitic flatworm representing a serious threat to humans in some countries. Opisthorchiasis occurs after consumption of raw or undercooked cyprinid fish infected by the metacercarial stage of the parasite. Due to its small size, detection of the parasite in fish fillet is time-consuming and difficult. Furthermore, isolated metacercariae can be identified to genus but not to species level using morphological features and molecular techniques are necessary. In this work, we describe the development of primers for a diagnostic PCR amplification of a 254-bp fragment of the cytochrome c oxidase I in the mitochondrion of Opisthorchis felineus metacercariae isolated from fish fillet, together with a validation protocol for this method.
