Abstract:
A region of mitochondrial cytochrome oxidase 1 gene (coxl) for Clonorchis sp samples from the provinces of Thanh Hoa and Nam Dinh, and Opisthorchis sp from human in Phu Yen province, Vietnam was analyzed by PCR. Nucleotide sequence of these coxl fragments was used to compare with Opisthorchis viverrini, strain Khon Ken (Thailand) and Clonorchis sinensis sequences originated from China and Korea. The results revealed that nucleotide sequence of Opisthorchis sp from Vietnam had absolute homology to O. viverrini (Thailand) but different from C. sinensis (from China and Korea). Clonorchis sp from Vietnam was similar with Clonorchis sinensis from China and Korea. Opisthorchis sp isolated in Phu Yen is, thus, molecularly indentified as Opsithorchis viverrini and Clonochis sp in Thanh Hoa and Nam Dinh is Clonorchis sinensis. Two species are different in morphology and molecular level.
