Using polymerase chain reaction (PCR), a portion of the cytochrome oxidase 1 (446 nucleotide and 148 amino acid) of mitochondrial genome of adult worm of small liver fluke from human in Hiep Hoa district, Bac Giang (CsNgBG) province was amplified. The nucleotide and amino acid of these sequences were comparatively analyzed with the known Clonorchis sinensis. The analysis revealed that the Bac Giang Clonorchis sp (in human) was similar (100% nucleotide and amino acid) to the Nam Dinh Clonorchis sinensis (identification was done); 99.6% (nucleotide) and 100% (amino acid) homology to the C.sinensis of Chinese strain (CsCN-Gen Bank AF 184619) and Korean strain (CsKor-Gen Bank AF 181889). Thus, the Bac Giang Clonorchis sp is identified as Clonorchis sinensis in Opisthorchidae family, Clonorchis genus. Phylogenetic analysis uniquely placed the Bac Giang Clonorchis sinensis to the group of Chinese and Korean Clonorchis sinensis.
